Yep, there's a truncate procedure in Delphi. One of
the old Pascal file-handling procedures. It doesn't look at though setting the
size of a Filestream is going to do anything.

Subject: [DUG] truncate a disk file
I'm fairly sure it's not possible but I thought I
would ask to be sure. Is there any way to truncate a file on disk
without re-writing it to a new file and deleting the old one? Say I have
a 40 meg file and I want to remove the last 128 bytes from the file. If
it's not possible, it seems rediculous that Microsoft did not provide a way to
do it. Logically, it should be possible by splitting the
directory entry into 2, and deleting the 2nd entry. Or maybe some
manipulation of the file allocation table.
Cheers,
Ross.
