Ok, so I have a program that stores some content in some database files locally. Does anyone know of tell-tale giveaways with regards to what DB such files would be for? ie. mySQL, Borland, Access, etc..

I have no problem going through them with a hex editor to look for details as well as looking for any library files that may indicate which DB format.

Suggestions welcome.

What OS your app runs on would be helpful

It's program running in Windows. Forgot to write that the first time around, sorry.

What does magic have to say about them? (aka the file command under Linux)

I couldn't find any magic number file that specfied any database files. That said, it might be something else altogether that there is a magic number entry for.

Hmm... There were:

.DAT (pretty generic sounding)
.IDX (along with this one)
.BLB (blob for binary data?)
.dod (the biggest files of all, leading me to think all the good stuff was in these)

I'd swear there were at least two others when I checked on Friday, but those appear to be it.

Could have been lock files. Did you have the application open at the time?

Those .DAT/.IDX extensions are a bit too generic. Could you upload a hex dump of the first (say) 1Kb of each of those files?

I found out what DB is being used. Funnily enough, they credit the DB company in their About window. Doh!

It's DBISAM which I'd never heard of before. Though I still don't know if they're doing something "different" with the larger files. Seems like the data is being purposefully obfuscated.

IIRC, I think you can read DBISAM files with MySQL. Worth a shot.

The program using these database files wouldn't by any chance be DVDProfiler, would it?

It's actually for a program for ordering car parts that lacks any type of export feature. Posted for a friend who uses it at his shop. The next version is apparently moving to SQLite - which would likely solve the access problems on its own. But my friend has also been requesting some export format which may also come in an update. I think he's happy for now.
