>How can I find out about the total size of a table (.dbf and .fpt)? I've tried it with the fsize() function, but this givs me only the size of the dbf file. Whats about the fpt file?

FSIZE() returns the size of a file only if SET COMPATIBLE is ON. And it works fine for any file. Try:

set comp on
?fsize("dbfname.dbf")
?fsize("dbfname.fpt")
set comp off
