Saved MPP project files save smaller than the original file - TIA

[Chris]

Have a situation where several users modify a common file on the network
called Engineering Schedule.mpp using Project version 2000 (9.0.2000.0224).
Everything was fine until one day, after making additions to the file, they
saved it and saw that the saved file was 219 KB smaller than the original
(the file size had decreased from 783 KB to 564 KB). Subsequent
modifications/additions to the reduced file result in a smaller file when
saved.
To troubleshoot, I installed Project Standard 2003 (11.0.2003.0816.15), but
my experience was the same whether I saved the file to the network drive or
to the local hard drive.
Is this a problem, or is project merely changing the compression and/or
deleting excess commands before the file is saved?

Usually it goes the other way (search this newsgroup for "file bloat"), but
this is a good thing and shouldn't affect your file contents. I don't know
the exact mechanism, but there is extra binary information stored in the
file for certain reasons and it appears this has cleared it out.

Hi Chris,

Welcome to this Microsoft Project newsgroup

This could be quite normal depending on how and when you save your projects.
If you suspect a corrupt file, you could try the suggestions in FAQ Item:
43. File Bloat? - Might be Corruption.

FAQs, companion products and other useful Project information can be seen at

Hope this helps - please let us know how you get on
