Managing Your NetID (account) Quota	Printer Friendly
Computing Services Information Document	UNIX

My Quota Defined

Every user account has a quota, or limit, on the amount of disk space that can be used for file storage. The disk space allocated to each person's file storage includes email as well as any other files saved to your network home directory (aka H drive) such as personal web files, SFTP files, documents and pictures saved in the public labs, and more. Some of the files stored in your network home directory are important system files that must be there in order for your email to function or for you to make use of certain university computing resources (i.e., lab systems).

Camden Computing Services has created an online program that allows you to check your quota from a web browser.

Warning messages are delivered to your Camden email account (netID@camden.rutgers.edu) whenever your remaining disk space drops to 100 MB. If your disk space drops below 50 MB another warning message is sent

If you exceed your quota, you have effectively run out of network disk space. Until you delete files or email messages from your account, you will not be able to save any more files to your home directory. You'll also be unable to receive new email messages while you are over quota. Anyone who attempts to send you email while you are over quota will receive a warning that their message was undeliverable due to your lack of disk space.

More importantly, when you exceed your quota, you will not be able to login to Web Mail or access your email or use other services.

If this happens, you will need to visit the HELP Desk on the main floor of Robeson Library. You may also call the HELP Desk at (856) 225-6274 or email HELP at help@camden.rutgers.edu via any other email account.

Any account holder may request more disk space. Depending upon the system, additional allocation may be as simple as justifying the academic need for it, or there may be charges incurred for the requested space. Students must print, complete (fully) and return the PDF form to the HELP Desk. You may also leave your completed form with Camden Computing Services' Administrative Assistant, Mary Sturdivant (BSB 126).

Faculty and staff with a dedicated UCS/IT support staff should contact same for their needs. Faculty and Staff who do not have a dedicated UCS/IT support staff may print out and complete the paper-based form or use the convenient online form.

Check My Quota

There are a number of ways to maintain your quota. The first and foremost is through awareness. An online tool is available to help you monitor your account usage (find "Check your NetID (account) Quota" at the respective link below):

• Students - http://clam.rutgers.edu/account_tools.php
• Faculty/Staff - http://crab.rutgers.edu/account_tools.php

NOTE: Although directly accessible on some lab systems as a "Home" directory or H: drive, each user account is actually stored on a network file server.

Delete Email

The way that email affects your quota will depend not only on how much email you receive, but also how you configure your email program to save/store other emails (sent, drafts, etc.). If you save a copy of sent emails and also store them on the server, then you may need to erase some old emails form this area, and/or not store them on the server, and/or not save copies automatically at all. More information on configuring your email program and the ramifications of some configurations can be found via the following link:

http://computing.camden.rutgers.edu/email/configure.php

One important factor in email management is spam. Rutgers uses spam filtering technology to tag and manage spam; however, you have the option of controlling how it may affect your account quota. More information on spam filtering for the Camden campus is available at the Spam Filtering page.
If your spam filter is set to place all messages marked as spam into the Spam-Messages folder, any email over 30 days old is deleted automatically; however, if you receive a lot of spam, it can still affect your quota for that 30 days, and you may wish to delete spam emails sooner. See the Spam Filtering page for more information (specifically the "Spam folder:" section).

Using Web Mail as an example, it is important to make sure to purge any deleted messages. When you delete a message in Web Mail, it is not removed from your account, but simply "marked" as deleted. Before logging out of Web Mail, make sure to click the "Purge Deleted" link (upper-right, above your list of messages). You can get a better idea of whether you are hoarding any deleted emails by making sure that you see a "Hide Deleted" link to the left of the "Purge Deleted" link. If you see a "Show Deleted" link, click it to show your deleted messages (which will also change the link back to "Hide Deleted").
It is also important to keep an eye on how much mail is being stored in any other folders you may have (i.e., Spam-Messages). You can access these by clicking the "Folders" icon/button in Web Mail, and then clicking on a folder name (link) to open it.

Clear Browser Cache

The following instructions assume that you are in one of the public labs on campus...

The cache is a place where web browsers (IE, Safari, Firefox, Chrome) store images and other files from previously-viewed web sites. These files are stored in an effort to make pages load faster on subsequent visits, and sometimes to make them available "offline" as well. Unfortunately, this also uses valuable space counted towards your quota.

Clearing the browser cache is accomplished differently depending on which browser you are using and whether on Windows, MacOS, or Linux:

• Firefox on Windows:
  1. Launch Firefox.
  2. Go to the "Tools" menu and select "Options..."
  3. Click the "Privacy" icon/button at the top of the window that opens.
  4. Click the "Cache" tab (far right).
  5. Click the "Clear Cache Now" button.
  6. Quit Firefox.
• Internet Explorer on Windows
1. Launch Internet Explorer.
2. Go to the Tools" menu and select "Internet Options..."
3. Click on the "General" tab.
4. Click the "Delete Files..." button.
5. Check the "Delete all offline content" box.
6. Click "OK" button.
7. Click the "OK" button to close the internet options window.
8. Quit Internet Explorer.

Return to top

• Firefox on MacOS:
  1. Launch Firefox.
  2. Go to the "Firefox" menu and select "Preferences..."
  3. Click the "Privacy" icon/button at the top of the window that opens.
  4. Click the "Cache" tab (far right).
  5. Click the "Clear Cache Now" button.
  6. Quit Firefox.
• Firefox on Linux:
  1. Launch Firefox.
  2. Go to the "Edit" menu and select "Preferences..."
  3. In the left column, expand the "Advanced" entry by clicking the "+" to the left.
  4. Click on "Network" under "Advanced."
  5. Click the "Clear Now" button for Offline Storage.
  6. Click "OK" button to close the preferences window.
  7. Quit Firefox.

Note: If you use more than one browser and/or more than one type of system (Windows, MacOS or Linux), you should delete the cache on each browser on each system, since they each store their cache in different places.

Delete Files (Windows)

Windows users can manage their H:\ drive from anywhere (campus, home or otherwise), by using a product called WebDrive, which is available for FREE to all university students, faculty and staff. More information on WebDrive can be found via the following link:

http://computing.camden.rutgers.edu/windows/webdrive/webdrive.php

The following instructions assume that you are in one of the public labs on campus...

1. Open My Computer (on the desktop or via the START menu).
2. Open the H:\ drive and find the file(s) or folder(s) that you wish to delete.
3. Click once to highlight the file or folder that you want to delete.
4. Use the "Delete" key on the keyboard (or the "File" menu's "Delete" option) and click "Yes," if prompted, to confirm deletion.
   DO NOT DELETE ANY FILES THAT BEGIN WITH A DOT (.) IN THEIR NAME.
   These "dot files" are special system files that are required for proper use of your account and other university computing resources.

NOTE: Your H:\ drive is the same as your "home" directory on Mac or Linux lab systems.

Delete Files (Linux)

The following instructions assume that you are in one of the public labs on campus...

1. Right-click on your desktop background to bring up a "Workspace Menu."
2. In the menu that appears, left-click on the "Files" submenu and then click the "File Manager" option.
3. In the window that appears, find the file(s) or folder(s) that you wish to delete.
4. Right-click the file or folder that you want to delete.
5. In the menu that appears, choose "Put in Trash."
6. Go to the bar at the bottom of the screen (aka, the "Front Panel") and click the arrow above the trash can icon (usually on the far right).
7. In the menu that appears, select "Empty Trash Can" and click "OK," if prompted, to confirm deletion.

NOTE: Your "home" directory is the same as your H:\ drive on Windows lab systems or your "home" directory on Mac lab systems.

Delete Files (Anywhere via SSH)

The following instructions can be used from any system (home, office, or one of the public labs on campus), as long as you have the ability to use ssh to access your account.

Connect to your account using ssh:

• Students connect to clamshell.rutgers.edu, using their NetID (all lowercase) and password.
• Faculty/staff connect to crabshell.rutgers.edu, using their NetID (all lowercase) and password.

At the Linux shell prompt (clamshell:~> or crabshell:~>), you can "rm" to remove/delete files or "cd" to change directories, as well as "ls" to list files.

In order to delete a folder, or more than one file at a time within a folder, type "rm -r <foldername>" (without quotes, and where <foldername> is the name of the directory you wish to delete or which holds multiple files that you wish to delete). The system will ask if you would like to "examine files in directory <foldername> (yes/no)?" Type "yes" or "y" (without the quotes) and press the "Enter" (or "Return") key to delete the file. It will repeat this confirmation process for each file in the folder, ending with the folder itself.
NOTE: Make sure that you are not "inside" the folder to be deleted (you can confirm your current location by using the "pwd" command). Also, if any files are not deleted, and left inside the folder, then deleting the folder will fail.

Here are some other Linux Commands to identify disk usage:

• df -k - shows how much disk space is left on the entire disk.
• du -k - shows the disk usage of the current directory and all of its subdirectories (and files).
• du -sk - shows the total disk usage of current directory and all subdirectories.
• ls -l - lists all files and the space used by same.
• quota -v - shows your current quota information (the "blocks" column is how much space you are using, while the "quota" and/or "limit" column shows your available maximum).
