Disk Quota

Disk Quota Allocation 

Each Mosaic account has an associated disk quota of 10GB. This includes all the files within your W:\, H;\ and U:\ drives. You can check your available quota by right-clicking on the Mosaic Health Monitor in the system tray of Windows.

Once you have used at least 90% of your disk quota, you will be presented with a warning every time you log in. See the section below on the Disk Quota Manager to help lower your quota. Once you are over quota, you will not be allowed to log in to Mosaic and must visit the Help Desk in order to lower your disk usage. This form is used to request an increase in your disk quota allocation.

All files on your Mosaic account must be stored on the W:\ or U:\ drive. These are the only places that your quota encompasses. Files stored outside the W:\ or U:\ drive, such as the C:\ drive, will not be synced with your account and you will lose them.

Please read our Policy on Additional User Disk Quota

Disk Quota Manager

The Disk Quota Manager provides a graphical interface (in Windows) to your Mosaic network storage showing you your disk usage in relation to your allocated disk quota. When you get a warning from Mosaic saying that your disk quota is low, open this tool to see where space can be freed up. This tool will also search different locations, finding your largest files for each location. From the search results window you can choose to either move files to an external drive, or delete files from your Mosaic account. You can use this guide to help you get started with the Disk Quota Manager.


  • If you are given additional quota, that quota will automatically expire at a predetermined time. (Your data will not be lost.)  If at that time you still need the additional quota, you have to re-submit a new quota request form.
  • Students will need a faculty or staff member to sponsor their extra disk quota.
  • There is no special form for an extension of previously allotted quota.  All types of quota requests are handled using the same request form.
