I moved this thread to the
Other PC Databases forum, as they are more likely to be from a 'desktop' database, and not files from a database
server.
.db is also the file extension for Borland Paradox databases. Wotsit.org has a link to the various Paradox formats listed
http://www.wotsit.org/list.asp?fc=6.
Keep in mind that .db is a common extension for custom applications as well.
If you open one of the db files with a hex editor like
HexEdit or winhex, it may give you an indication of the database type. Try this and post a screen snapshot of the results... (Be careful to not make any changes though.)
Per the above spec info, if the file is a paradox data file, the first two bytes (offset 0000) are an integer which will contain the record length for the records in this table, the integer at offset 0002 is the header size (usually 2048,) and the byte at offset 0004 will be 0 or 2. 0 means that the file is an indexed .DB file, 2 means that the .DB file is unindexed. (A value of 1, or 3 through 8 mean that the file is an index file, with a file extension of .PX, .Xnn, .Ynn, .Xnn, .XGn, .YGn, or XGn respectively. (where n is a number 0 through 9)
Excel can import a good many different formats via ODBC. The office installation disks have the option of including quite a few ODBC drivers (including, I believe, paradox) during the install or repair of the installation, as does Visual Studio 6. (I believe the same is true of dotNet versions of visual studio.) You might also check the Borland web site.
