Absolutely. Just use a plain old memo field. I do it all the time.

REPLACE MemoField with FILETOSTR('C:\DevPath\FileName.pdf')

STRTOFILE(MemoField, ADDBS(GETENV('Temp')) + 'FileName')

... code here ...

ERASE ADDBS(GETENV('Temp')) + 'FileName'

I store the actual filename in another field in the same table where the memo field is along with file size, etc. so I can check the file once I recreate it.
