Worldox

Most File Systems have unique ways for doing things, but also many things in common. On a Macintosh you might have some extended attributes, or that pesky hidden .DS_Store file no one really knows why it’s there. On Windows you may find a hidden thumbs.db file throwing off your file count. Hidden files are everywhere. Many have a real purpose, and that purpose may be insignificant or important in finding or giving context to other files.

While processing a collection from a USB drive the other day, I came across a few files I hadn’t seen before. They were hidden files nestled in with a few folders of PDF’s. They have a unique name, so I figured it would be easy to find some documentation on them on the web. Turns out, there is very little.

-rwx------@ 1 tyler  staff    235 Aug 22 00:04 XNAME.CRS
-rwx------@ 1 tyler  staff    235 Aug 22 00:04 XNAME.LIB

The files were only a couple years old, so I figured there had to be some modern software which created them. A look inside the files with a hex editor didn’t provide much information.

I was about to give up since there wasn’t much data and since they were hidden files, I assumed they were probably just some cached files with little value. But wanting to learn more I did some more digging and at first thought they might have something to do with DropBox, as a user said they just showed up one day, but later found they probably were created by some Document Management software known as Worldox. I found a support page claiming these two files are part of a database.

XNAME.LIB	Contains document numbers (DOS names), extended names, and file security information.
XNAME.CRS	Contains custom profile field and version control information.

There is a key term in the definition of XNAME.LIB, “extended names”. I was curious what that meant and found Worldox has been around awhile. The World Software Corporation has been around since 1988 and Worldox was released in 1993, but before that it specialized in an interesting DOS software package called “Extend-A-Name” or “Extend-A-File”. The name gives away its purpose, it literally extends the name of the limited 8 Characters you could use in DOS. I can remember trying to decide on a filename that would accurately describe my file so I knew what it was later on. 8 characters is not enough to explain the content of a file, especially if you have hundreds or thousands of file to manage.

Extend-a-file was software which bonded with another piece of software like WordPerfect and loaded itself in memory. Then when you went to create a file or locate a file within WordPerfect, Extend-a-File would take over and allow you to create a file with a traditional 8 Character name, but also a name much longer.

This extended name allowed you to describe the files content with much more detail. Making it also very easy to find previous documents.

Pretty slick, this software really would make a big difference to managing a large amount of files in the old DOS days. Ok, it adds extended names, but where is this information stored? That is where the XNAME files come into play.

This XNAME.LIB was generated by a running copy of XNPLUS circa 1990, bonded with a copy of DisplayWrite 4. It adds much more information within the “Library”.

So it seems this method of storing the extended filenames and other metadata started in the Extend-a-File software and has been brought along and used in modern versions of the Worldox Document Management software. Much of its purpose to extend an 8 character filename to around 60 character is no longer needed as most systems now allow for filenames with at least 256 characters. I imagine there is more the software can add to these files, but found that the samples I have really don’t have any information in them at all. The Worldox software seems to be marketed toward law firms and others who have a lot of documents to manage, but I have been unable to find a way to play with the software to see what can be embedded within the XNAME.LIB files.

There is also some discussion out there about wether to backup these two hidden files and what might happen if they are lost. Regardless, you may want to think twice before tossing them as I almost did. They could contain valuable information needed to give context.

I am not sure it is possible to have a good signature for identification of these files. The samples I have and others I found online, here, here, here, and here, just don’t have much data within them. In fact they are all exactly 235 bytes. The only consistent byte within them and the samples I generated from XNPLUS is “4C” at offset 150, but everything else seems arbitrary. Here is a sample I generated from XNPLUS if you want to take a closer look.

A2R / MOOF / WOZ

There seems to be a never ending growing list of disk image formats. Many have features which are specific to the media and format. If you have ever imaged an older Macintosh floppy you know they are special. If you add in copy-protection which many early Apple II floppies have, and you need special drives, hardware, and a special format to store the floppy data.

When imaging special media, especially with unique media, it is best practice to image the floppies at the magnetic flux level.

Floppy disks contain magnetic fluctuations which are measured and recorded using specialized equipment. A popular method is using a Kryoflux board, floppy drive, and software. The software communicates with a custom controller board connected to a floppy drive through USB. If you are interested in the different controller boards, a good list has been compiled here.

A Kryoflux, fluxengine, greaseweazle, all can image specialized disks like a Macintosh 800k floppy, but the best controller board for them is an Applesauce setup. They are specifically designed to for the task. With that task, comes a few specialty formats.

A file format which can store flux data is a bit different than a regular disk image format. The flux data contains all the low-level recordings which can then be interpreted into disk images much like the original floppy. In the case of an Applesauce flux image, it can contain all the small nuances of the original floppy, this includes recording any copy protection or other creative methods used by software vendors throughout the years. The format used for storing this flux data is the A2R format.

A2R is in its third iteration. Let’s take a look at the basics of the format.

The A2R format uses a chunk system to store the various pieces to the format. Earlier versions used a STRM Chunk to store all the raw flux data. Version 3 changed to a RWCP Chunk to store all the raw flux data. Applesauce uses a 2-pass imaging process, doing a rapid imaging to determine where on the media surface track data exists and then a second pass that captures longer durations for processing and error correction.

Once the full raw flux data has been captured that data can be interpreted as a disk image. The Applesauce software is able to make a regular disk image, a Disk Copy 4.2 file, which are well known and identify in PRONOM as fmt/625, but can also create a couple of special disk image formats which allow for special nuances on an original disk.

The WOZ Disk Image format is an offshoot of the Applesauce project. Capturing highly accurate bit data is of no use if you don’t have a container to hold the data. The WOZ format was designed to be able to contain every possible Apple ][ disk structure and layout. It can be so accurate that even copy protected software can’t tell that it isn’t an original disk.

The WOZ format has become very popular in the Apple II community and is ideal for emulating all the old games and software titles popular in the early 1980’s. You may have guessed where the name comes from. The internet archive has a large collection of WOZ disks in their WOZ-a-Day collection. The file format of a WOZ disk image is also a chunk based format similar to the A2R format, it has two versions. Let’s take a look.

Unlike a common disk image, a WOZ image contains more than the bits on the disk, it contains a mapping of all the tracks and the associated data, this is how it can even contain copy-protection usually only possible with a physical disk. The ‘TMAP’ chunk contains a track map and the ‘TRKS’ chunk contains all the data.

What the WOZ is for the Apple II, MOOF was made for the Macintosh. You may wonder what is with the funny name, but there is a long history around “Clarus the Dogcow”. I’m sure this factoid will help you impress your friends or win at trivia night. Again, the purpose of the special format for Macintosh disks is to allow for emulating disks, even with copy protection. You can also find quite the collection of old Macintosh software in the MOOF format on the Internet Archive, even emulate your favorite game, such as Dark Castle, which I played for hours as a kid. Also a chunk based format, let’s take a look at the header.

All three formats created for imaging and emulating Apple and Macintosh software are well documented and open. They are also well suited for preservation as they can contain extensive metadata in the INFO chunk which gives provenance information on the source of the files. The Applesauce software even has a camera to photograph the disk itself for archiving. All of this makes these formats great for preservation and emulation. Take a look at my proposal for a signature on my Github.

Binder

Posted on by Thor Leave a comment

Microsoft is never in short supply of file formats. They have made many changes over the years. Introduced lots of products, some lasting longer than others. The list is quite long.

One such software was called Office Binder. Introduced with Office 95, it was a companion application to combine a number of OLE objects together in one “Binder”. Meant to be the digital version of an Office Binder one often uses for presentations or proposals.

You could add sections and include Word documents, Images, Powerpoint, Excel spreadsheets, basically any OLE object. Of course a Binder file itself was an OLE compound object. They had the extension OBD, and templates used OBT. The PRONOM registry has PUID’s for the different Binder versions, but there are some issues.

PUIDFormat NameFormat VersionExtension

Turns out only one of the PRONOM PUID’s has an actual signature, the others are placeholders. So when I run Siegfried on an Office Binder 95 file, it comes back as fmt/240 which points to an Office Binder 97-2000 file. It’s a simple signature, looking for an internal file named “Binder”, which is inherent of all the Binder file types.

    <ContainerSignature Id="5500" ContainerType="OLE2">
      <Description>Microsoft Office Binder File for Windows 97-2000</Description>

        <File>
          <Path>Binder</Path>
        </File>
      </Files>
    </ContainerSignature>

Taking a look inside the Office 95 Binder file, we can see the “Binder” file.

The bytes within a “Binder” file has some patterns, but nothing decipherable.

Microsoft Office Binder was only included in three versions of Office. Office 95, 97, and 2000. Let’s look at the other two versions.

It looks like version 97 and 2000 have an extra file. The “HdrFtr” file seems to reference a Header and Footer, which according to documentation was a feature added in Office 97.

What’s new in Office Binder 97

Office Binder makes it possible for you to group all your documents, workbooks, and presentations for a project in one place. To get started with Office Binder 97, add a new or existing document to your binder. Use the new Office 97 features while you work in a binder……. Print headers and footers for a binder

We can use the “HdrFtr” file within the container to differentiate between the 95 version and 97-2000 formats. Perhaps, a closer look at the DocumentSummaryInformation file in the future, might help with a more precise identification later. There doesn’t seem to be anything to distinguish an OBD file from a OBT template file, so those PUID’s may not be needed. The other format related to the Binder software has the OBZ extension. It is called a Wizard template file in some documentation, but I have been unable to find any type of “Wizard” functionality in the Office Binder Apps to generate a file. The OBZ format seems to have something to do with macros in Visual Basic. Luckily there are a few examples available on Office install disc‘s.

Sure enough, the OBZ file has a Visual Basic macro (VBA_Project). Unfortunately, it appears to be nested in an additional folder within the container, with a variable number number which is likely to change from file to file. That fact will make identification in PRONOM much more difficult, as the signatures are not designed for variable names. Possibly something we can investigate later.

Microsoft Binder was only released in Office 95, 97, and 2000, but was supported in Office XP and 2003 through an UNBIND.EXE application which would simply separate all the different objects back out to the individual files.

The Microsoft Office Binder is not included in Office 2003. However, if a Binder file created in a previous version of Office contains information you want to access, you can use the Unbind tool to pull out the information and save it in the formats of the appropriate programs. In order to do this procedure, the Unbind tool must be installed.

    As always, you can look at some sample files and my proposal for updated signatures on my GitHub page.

    UFO

    Posted on by Thor Leave a comment

    Researching file formats isn’t for everyone. Others may find it boring or even odd. Trying to explain to others the nuances of a binary format versus a container format would bring many tears. Their reactions sometimes are similar to hearing someone explain their belief in aliens. Passionate, but a bit on the crazy side.

    So with aliens and containers on my mind, let’s take a look at a format with the extension UFO. It is not an unidentified flying object or a UAP, it may as well be an unidentified file object, but in this case it is a “Ulead File for Objects” format. It is the exclusive file format for use with the PhotoImpact software from Ulead Systems, a Taiwanese developer known for many popular software programs. First released in 1996 with version 3, the PhotoImpact software was marketed as “a fully object-based tool, which pioneered a number of important innovations“.

    The reason it was a considered a full object-based tool was the UFO format is based on the, at the time, popular OLE Compound File Storage object format developed by Microsoft. So by using some OLE tools we can take a closer look at some of these Unidentified File Objects……..

    Well, it is a OLE file, but is unrecognized/unidentified by the oletools software. It also appears to be missing the root entry and CLSID you commonly find in OLE files. Since this is an OLE container we can also just use 7zip to peek inside as well.

    In this sample file, we have a bunch of directories and objects, but none of what we expect to see in an OLE file, such as a “SummaryInformation” or “DocumentSummaryInformation” like we would see in a Word DOC file. By not having the standard contents of the container, it makes these files very specific to PhotoImpact software.

    Here is another UFO file from the last version of the software PhotoImpact X3 when it was owned by Corel, but phased out in 2009. This is the basic file structure with no objects added to the file. We can be fairly confident these are the base files in most every other UFO file. It doesn’t have any of the “OS” folders which contain the objects, so I think the LtfHeader file might be our best bet for a signature. Let’s take a look at the Hex values for a few of them.

    Making a signature using the first 8 bytes of the LtfHeader file appears to have worked for all the 3,400+ sample files I have collected. Problem is it also worked for another extension found in the some of the later versions of PhotoImpact.

    When you have successfully finished your template, make sure to save it in the Ulead File For Photo Project format (*.UFP). This allows you to open and use your template in the Photo Projects dialog box. In the Template tab, click Open Project and browse for the created file.

    They appear to be a template version for the format so we should be fine just adding the extension to the same signature.

    Well, this Unidentified File Object is no longer unidentifiable. Was it sent by aliens? Possibly, but at least we know where these UFO’s came from, PhotoImpact. Take a look at the samples and proposed signature in my GitHub.

    Also be sure to join us at this years iPres conference and attend our workshop on container signatures in PRONOM!
