Introduction to DS-Filestore

DS-Filestore is the service providing students, staff and groups with access to centrally backed-up file servers. A personal filespace quota of up to 3GB is included with all Desktop Services accounts.

Personal filespaces

Access your filespace from any computer connected to the CUDN network (including MCS computers) or from a computer outside the University network using the UIS VPN service.

By default, your filespace can't be seen by other users, although you have the option to share files.

Your filespace is centrally backed-up and you can also use it to publish personal web pages.

Group filespaces

UIS also provides facilities for group filespaces, most commonly used by University Societies. Limits and access rules for group filespaces are different.

Quotas and usage

Each user, other than temporary accounts, is given a filespace limit of 3GB. This is an upper limit; there is not enough space for every user to keep their full entitlement on the fileserver permanently.

If you run out of filespace, you will not be able to create any new files. You should delete all unwanted files; if you think you have a real need for more space, then you can apply for an increase.


The central backup service is designed to recover from major system failures. It is not always possible for UIS to recover individual user files deleted in error.

If you are using DS-Filestore to store the primary copies of your files, you are responsible for ensuring you have kept backup copies elsewhere.


Filenames can be up to 255 characters and should not include the following characters (some are permitted on a Macintosh but it is safer to avoid them):

: * " / \ <> ? |

If you are writing web pages we recommend filenames should only contain lower-case letters (a-z), digits (0-9), and the punctuation characters . , - and _ (full stop, comma, hyphen, underscore). Spaces should be avoided.

Managing your filespace

How to check your filespace usage

From an MCS computer:

Windows: Click the FileSpace icon in the taskbar.

Linux: Select Applications > Utilities > Quota.

Mac: Select Applications > Utilities > PWF Account Management.

The only way to check your quota usage remotely is to login to MCS Linux using ssh or slogin.

Deleting files

Unwanted files should be deleted promptly, but do not remove files unless you are sure what they are. Some files are created in your filespace by particular application programs and should be left there.

  • Do not save files inside the Windows, or Appscfg.MCS folder.
  • Do not delete any file whose name starts with a full stop.
  • Mac users should not touch the Library folder.
