    I have a MS Project 2010 with approximately 500 tasks file size 22MB. We added 5 additional tasks, the file grew to 40MB. Can someone tell me the root cause of this problem.

    Hi ,

    Project has never done a good job of clearing up after changes and file bloat is quite common.  Try a simple Save As… to see if that works. If not, there may be some corruption – you could try the suggestions in FAQ Item: 43. Handling project file corruption and/or bloat. FAQs, companion products and other useful Project information can be seen at this web address: http://project.mvps.org/faqs.htm

    Hope this helps – please let us know how you get on 🙂

    Mike;

    Thanks for your  tip; Tried Save as, and it dropped the file size from 40MB to 4 MB. But for a 500 task plan 4 MB is still fairly large.

     

    Your thoughts!!

    Glad it worked – try it again.  The size of a project file depends on many other things than just the number of tasks,  For instance, you could have a 5 task project with 100 resources assigned.  Or you could have one resurce with manually entered Work that varies day by day for months.

    Appreciate the tip.  For the good of the order, I have had the same experience with Project 2007.  The file is about 300 or so tasks with about 20 resources.  It grew over time to over 4 MB.  The save as technique worked in that it reduced it to just over a MB.

    I found users attaching large amounts of text and even graphics in the Notes section – may want to check for that as well.

    Tried first option mentioned here and helped: https://answers.microsoft.com/en-us/msoffice/forum/msoffice_project-mso_other/project-large-file-size/e0c585a7-bcc8-4eda-b25b-7b7f073b9e16

    But not sure when we do a Save As, it will clear off any required information and safe to use the new file without any risk of losing information

    I have had the same problem this morning did a save as and he file shot from 10MB to 20MB. I took all the colour out of the plan and it reduced back down to 9MB. Still rather large though but was surprised that colour to text would add such an increase the file size.
