About Quotas
There are several quotas that may be associated with your BU Login, incuding print quota, mail quota and ACS disk quota. Your quotas are assigned according to academic status.
You can determine how much of each quota you are currently using by going to the MyACS site at www.bu.edu/computing/myacs.
For more information about quotas, checking quotas, and fixing any quota problems, please visit the PCSC's quota page.
ACS Disk quota
The rest of this page is specifically about ACS disk quota, which is the space available for storing files on ACS.
You can view your disk quota usage with the MyACS tool as above, or by logging in to ACS and typing the command quota at the system prompt. In the following example, Fred's files are using 2672K of disk space.

The disk_clean program
If you are find that you are approaching your disk quota, you can run the program "disk_clean" to help you find files which are likely candidates for deletion. The disk_clean program does not delete files, it simply looks through your directories for files which are usually considered temporary or old. Examples include core files (large pictures of memory which you will never need unless you plan to debug programs), editor backup files (e.g., Emacs saves the old version of any file edited under the name "filename~"), old versions of files used by news readers and mail, and intermediate files created by programs such as TeX and LaTeX.
Deleting files with the rm command
The UNIX command to delete a file is rm <filename> (substitute the actual name of the file and remove the brackets). If you need help, please talk to someone at the Consulting Services Help Desk.
If you need to increase your quota
If you find you are unable to store your work within your disk quota, you will need to fill out a form requesting additional disk space. Students must obtain the approval and signature of their faculty advisor or the course professor on this form.
For more information
For more information, you might like to see the "quota" man pages -- just type man quota when you are logged into ACS.
