  4. Worked perfectly and easy to follow.

    I have multiple drives and my OS/Apps drive is an SSD. The outlook OST’s constant connection to my remotely hosted exchange server made my computer stutter. By putting it back on a SATA 7200 drive, we’re back in business!

    Thank you!

  19. Hi
    I have Windows XP and tried:
    control panel >> Mail >> Data Files >> (select mailbox) settings >> Advanced >> offline folder File settings
    the file field appears disabled. I cannot change the path.

    What am I missing here?

  20. Really help full, thanks!!!

  21. Will NOT work with hotmail.ost files, at least those that involve the Outlook Connector, which is the only way to get IMAP with Hotmail (Live Mail just uses a different form of Connector – neither will work!)

  22. Thanks. Exactly what I was looking for to solve my PC memory issue.

  23. Thanks. It did the job!!!

  24. There is another way to solve this problem (and for other applications that install on your C: drive without giving you any other option) ESPECIALLY useful for SSD owners, and that is with SYMBOLIC LINKS.


    Let’s say you have an program called XYZ that has installed itself and all its data on your C: drive at


    and that folder is filling your SSD fast. To move it to your D: drive without upsetting anything, do the following:-

    1) First stop the program or service that is running that XYZ app.
    2) Move the C:/ProgramData/XYZ to your other drive (e.g. D:/C-ProgramData/XYZ)
    3) Run CMD as Administrator (Google if you don’t know how).
    4) At the command prompt, enter MKLINK /D “C:/ProgramData/XYZ” “D”/C-ProgramData/XYZ” and hit enter.

    MKLINK will create a kind of ‘shortcut’ folder with the name XYZ in the C:/ProgramData folder that points to the new location on your D: drive. Now, whatever program looks for a file in that folder on your C: drive, will be automatically rerouted to the folder on your D: drive.

    I run Windows 8 Professional and found that my Search service was creating a massive file (30GB+) on my 120GB SSD. I stopped the Search service, moved the folder, ran the MKLINK as above, and now that folder is on my D: drive where there’s heaps of room.

    I did the same for my Outlook folder, which contains an otherwise-unmovable Hotmail OST file – and all works well with my SSD now having over 40GB free once more!

    If this helps you, pay it forward!
