Home Directory

Your home directory is a directory for your exclusive use where you may store your files. It is the Z drive under Windows and is the directory you are taken to when you log into Linux. All of the files in your home directory are backed up to tape every other night.  There is a limit to the amount of space that you have on your Z drive:

  • Undergraduates have 2 GB available
  • Graduates have 6 GB available
  • Researchers have 10 GB available

Password Changes

You can change your password from any machine on the ENGR network. Instructions can be found on the Security Page

Should you forget the password to your ENGR account, you must go to the systems office in Bourns Hall A344 with Photo ID to reset your password.

Going over quota

If you go over your quota, many problems with your account may occur. Such problems include:

  • Your profile will no longer update.  For example, if you delete a file on your desktop and it reappears when you log in again.
  • You are unable to receive mail.

Delete data from your Z drive to prevent this from happening.  Scroll down to check your current home directory quota.  Note: if you are not forwarding your mail to another email address, mail will also be included in your quota.  Delete unwanted mail in this case to reduce your quota.

Checking your Quota

Log in to,, or and execute the quota -u command. Click here to view the web tutorial on "How to connect to our computational Servers."

Saving space

Deleting files on your Z drive will free up space, however there are some files that you should NOT delete under any circumstances.  Deleting these files or folders will cause serious problems for your account!  They are listed below:

  • .bashrc
  • .profile
  • .forward
  • .procmailrc
  • Maildir/
  • ~snapshot/
