Try a PACK first

>>>I got this error "Not enough memory for file map" when I tried to add a field to table structure. I got like 4 giga of memory. And I think the 3 memo fields in the table has something to do with the error. the FPT file seems somewhat having some corrupted data.
>>>There are like 50 different tables in the Database. Only one table is giving me the error.
>>>
>>>I can't add field to or delete field from the the table. I tried PACK , it ran without problem. But I am still getting the error when trying to
>>>add a field to the table. The table has 51 fields, record length: 484
>>>Is there any way to clean up the fpt file ?

>>One thing you could try:
>>
>>1. Backup all your database and table files (including CDX, FPT etc.)
>>
>>2. Copy all the data from the suspect table to a temporary one in the same database: COPY TO TempTable DATABASE MyDatabase ALL WITH PRODUCTION
>>
>>3. See if you can successfully modify the structure of TempTable. If you can:
>>
>>- Check that TempTable seems to have all the data
>>- Make sure you have a good backup!
>>- ZAP your original table
>>- USE the original table, and APPEND FROM TempTable
>>- Test to see if the issue with the original table is fixed
>>- If so, remove the TempTable from your database

>Hi Al, thanks for your reply. I just tried your method but I got the same error during the excution of the COPY TO command. It ended up getting a incomplete copy of the original table.
