Dear Friends, My Exchange server 2003 ver : 6.5.7638.1 Drive C almost full, (file PIF its about 30Gb / always increased), Now Free space : just 1 Gb (always decreased) What should I do to keep my System drive ? Actually, PIF file makes my Drive full, I dont know what it use for.. BR's Sendy

The PIF file type is primarily associated with Windows. A Program Information File dates back to the early versions of Windows. So dont delete this. How ever the most surprising thing here is the size of the file, which is way to much. Can you put the same query on size on windows forum on http://social.technet.microsoft.com/Forums/en/category/windowsserver/Now you need to look at other side where you are running out of disk space on exchange. Do you have any other drive or some slots free on server to put in some drive? ANy thing else that you can delete from the server in order to gain some space? How big is the log file directory?Raj

Dear Raj, Actually, I dont have any free space on this server. So, can i move to external disk? (for back up) What happen if i cut and move to my external disk? exchange system will be down? user not able sending and receiving email anymore? please give me explanation. Thank you very much Sendy

Sendy,Never recommended to move to a USB drive. You need to think on getting some extra drives on the server.When you say external drive, are you takig about SAN or a USB drive. SAN is fine and you will not have any issues but never a USb drive. Raj

Dear Raj, I mean External drive (external harddisk with USB port), I have external harddisk with 320GB free space. is there any issue, like system down or something if i move PIF file? because C drive almost full. Thanks Sendy
