Yeah, I just checked that out and replied to SB :) So to correct the last paragraph in my post its

(a) .and. !(b)

:)

>More specifically to what Sergey said, when you increase the size of an existing memo record, the *entire* memo field is written again to the memo file, in another location (at the end of the file, I think). The memo record that was already there is still in the file, wasting space.

>>In addition, old memo data is not removed from the memo field when it is replaced with new data. The old data is still in the FPT file too. So a PACK MEMO does two things (a) remove all the old data and (b) rejoin each memo fields seperate pieces. But still, how this all ends up on the HDD is up to the OS and state of the HDD.
