I am using an application where the programmer changed dbf files (DBase IV) to .fmm files. If you change the extension to dbf I can open it in Access or excel. I can associate .fmm to excel and access but cannot import external data from the files.
I do not change the extension every time i want to manipulate the data as this can cause data corruption on saving. I would rather create a a data source or make it appear on the list of DBase files.
