>foxuser.dbf and .fpt what does it do?
FOXUSER is the vfp resource table, which keeps track of changes made to the Visual FoxPro environment. When you work a lot, it gets big and sometimes can give strange things.
From the Help:
***
The resource file is a Visual FoxPro table that contains information on system and user-defined resources such as keyboard macros, preferences, system window locations and sizes, diary entries, and so on.
