Thanks for your reply.
Cause the particularity of PST file. If divide the pst file in outlook, the
file size of the old pst file is same as before dividing except compress
manually.
So the file size may not be the actual size.

the Win32 API's or whatever is the best way to get overall size of a PST

How can I get current pst file size in outlook? Is there a parameter in
objInfoStore can get the size directly, not by FSO ?
Thanks.
