I hope their loss was not an unknown bug in DFB.

So do I.

Not that it's any consolation, but I've never had anything like this reported before.

I'm guessing you haven't been saving an occasional backup to minimize the loss? There are many reasons data can be lost.

Anyway, hopefully, the database still exists. Firstly, don't run DFB anymore until we see if we can find the files.

There are only 3 data files used by DFB in normal operation:
DfbConfig.cfg This plain text file contains the settings used by DFB such as window position and location of media files.

DfbSongData.dat This is the main database file. It contains all the songs.

DfbSongData.bak An auto backup of the main database file. Unfortunately, being an automatic system, a bug in DFB is likely to effect this file as well as the main DB file.

All the files are stored in a folder called DigitalFakeBook in Application Data under your user account.
In Windows XP that is normally something like:
C:Documents and SettingsJohnApplication DataDigitalFakeBook

In Windows 7 it should be under something like:
C:UsersJohnApplication DataDigitalFakeBook

The reason I can't be absolutely sure where the DFB data folder is located is because DFB asks Windows for the <AppData> location.

If you are running it in portable mode the data files will be in the same folder as DigitalFakeBook.exe

If you cant find the data folder, then please let me know which version of Windows you are running and if you are using the portable version or not.

If you can see the main database file and the backup, check the sizes. If the backup is much larger than the main data file you may be able to get most or all of your songs back.

Important: Firstly, copy all the files to another location as a backup in case this next step doesn't work.
Next, delete DfbSongData.dat and rename DfbSongData.bak to DfbSongData.dat

Now, run DFB and a new auto backup will be created.

If you have found the files and they are both about the same size and too small, then unless you have saved a backup i'm afraid the songs are gone. :( The database file normally averages about 1K per song.
