There are 4 special network areas for file storage, backup, or sharing. Users with FACS network accounts running Windows will see these as the M, P, Q, and T drives.
The Home Directory or M drive is for personal file storage, is backed up to tape daily, and has a quota of 1000 Megabytes (1 Gigabyte).

The P drive is useful for working on files that are associated with your department, is backed up to tape daily, and each departmental area has a 10 Gigabyte quota. Your P drive will not show the Departmental folders, but rather the contents of files and folder in your Department. If you need to have folders created in your P drive for collaboration purposes, ask your Office Manager or send a request to helpdesk@fcs.uga.edu

The Extension server is seen as the Q drive, available to Cooperative Extension personnel and is backed up daily.

The Temporary storage area is seen as the T drive, is not backed up to tape, and has a quota of 10 Gigabytes. Also, the contents of the T: drive are deleted every Sunday night.

It may help to remember the drives if you think of HoMe, DePartmental, and Temporary.
For the Q: drive, you'll have to create your own mnemonic.
