GRACE uses the Glue AFS cell for most filesystem needs. The actual path to a class account from any Glue machine is the following:
/afs/glue.umd.edu/class/[semester_year]/[college]/[course_number]/[section_number]/Within this directory, the following folders exist:
| Folder | Student Permissions | Instructor Permissions | Purpose |
| .db/ | none | none | information needed by Glue staff |
| public | read | read/write | area for instructor postngs |
| instructor | none | read/write | instructor's personal space |
| backup | read | read | holds a one-day old copy of all folders and subfolders in this directory |
| student/[login_name] | read/write | read | individual student space |
| submit/[login_name] | insert only | read | where the submit script places files |
