Going from FP to Access??? Shudder!!!!
Why step down in performance and capability?
If anything, I'd put the data into one of the SQL Server's (MS SQL - Express or Full, MySQL, etc.)
And if I had to migrate the application to something, I'd migrate it up to VFP9. 2nd choice for the application would be into one of the .NET languages
Regardless, there are 3rd party tools out there to help.
One is dbConvert ( dbconvert.com )
As Tamar advised you above, the file types that you will need to look for are:
* DBF files (Data Table files)
* and their file-name associated FPT (Memo field files)
* and IDX/CDX (Index files)
For old Foxpro (not Visual Foxpro), you will not have a Database container (DBC,DBT,DBX) files to hold the Data Tables.
Good Luck,
