They seem to be associated with Memo fields but Memo fields are contained in .FPT files, I thought. Is it some kind of backup? Can I delete them without damaging the current data?
Also, where can I go to answer such questions in the future?
Yes, TBK files are backup copies of the FPT file and are created when you make a structure modification to the main DBF (which makes a BAK file). As long as you are comfortable with the structure change you can delete both the BAK and TBK files.
Yup. As Robert said, it's the table's memo file's backup.
Can I delete them without damaging the current data?
Yup. As SGLong said, if you're secure with the structure, delete'em. FWIW, if you ever encounter a problem when attempting to modify the structure of a table, you can delete the .dbf & .fpt and rename the .bak as .dbf and .tbk as .fpt. Bare in mind this only applies to structure, not data.
where can I go to answer such questions in the future?
or to your MSDN disks if you are a MSDN library subscriber. The MSDN is a greatly under-used tool. For example, if you had done a search for TBK and FOXPRO, you would have found your answer in a matter of seconds.
Also, the VFP help file is a esential first-stop reference for VFP syntax and other VFP related issues. Jon Hawkins

Sorry for not answering your other questions; I was in a rush to post so I could beat out SGLong and Jonscott8. :-D
If, in the VFP command window, you would type: help tbk you'd find a list of the file extensions.
Remember that you can type help keyword or phrase in the command window for a help search on that word or phrase, and you can highlight a keyword in code and press F1 for the same effect.
