Maximum allowed disk space

First thing, how much disk space do you have anyway? Here is a general rule of thumb:

    • When a CAE account is created, it is given a base allotment of 10 GB.

    • College of Engineering undergrads and grad students are given additional 15 GB (25 GB total).
    • CoE faculty/staff get an additional 40 GB to the base allotment (50 GB total).

  • Other factors that affect allotment include special course requirements and purchased disk space.

Checking current vs. maximum disk usage

Although there are a few ways to check your disk space from Windows and Linux machines, CAE suggests checking from your CAE account page.

This is the easiest way, just access this link from any computer:

Emptying Trash

One useful tool is Windows Trash Analysis, great for clearing clutter. Unless your trashed files (Recycle Bin in Windows) are emptied, they still count against your disk quota.

To find large files in your file space, please refer to KB article [Link for document 17845 is unavailable at this time]

Checking Disk Quota and Usage

There are a few ways to check available and used disk quota. Detailed information can be found in here

Reducing disk quota

There are several ways to delete your unnecessary files from your files space:

1) log in to CAE Windows machines and delete all the files that you won't need. 

2) go to and log in using your CAE log in and password and delete files from there.

Note: if you are trying to access this page outside the campus, you need to be connected to VPN first.

3) use Linux machines to open up Terminal, and remove files using "rm file_name" command.

After deleting files, make sure that Recycle Bin is also emptied. Please allow system to update and reflect the changes, it will take about 30 mins. Re-check disk space usage.

If that doesn't clear up enough space, you can move files to DoIT's Box service.

Alternatively, you can trying moving some of the files to a flash drive or other storage media.

Reducing disk quota after grace period passed

There is a 7 day grace period given to access your files safely and get the account under disk quota. Moving files is restricted after this period passed. If your filespace is grossly over quota, you will not be able to move files at all. The grace period will not apply. You must delete files until your account is below quota. 

First thing you can do is empty the Recycle Bin and see if it brings the account under the quota, if it is delete files as outlined in above instructions.

If not, there are couple options to chose from:

1) use Linux machines to empty the trashcan in the Gui, or open up Terminal, and remove files using "rm file_name" command.

2)  if using windows file explorer, highlight the files you wish to delete, and press Shift+Delete which will lead to "permanent" deletion of files

If you still have problems with deleting files and going under the quota, contact CAE Help Desk.

When you are in a CAE Windows lab, your files can be found on your I drive. In CAE Linux labs, this same space will be your default home directory.

These instructions help you access your files from computers outside CAE labs. 
**Note you can only reach your network drive from any UW-Madison campus wireless network, or the Engineering or WiscVPN. Details on how to connect to the Engineering VPN here: Installing and Connecting to VPN. If you have not yet activated your Engineering VPN, please follow the instructions here: Activating VPN Access**

How to map your CAE home directory


  1. Open "File Explorer" (Folder Icon in taskbar, otherwise under start menu)
file explorer
2. Right Click "This PC" on the sidebar and click "Map network drive"
After right clicking "This PC" click "Map network drive" in the context menu
3. In "Drive:" enter any available letter
4. In "Folder:" enter \\\[login_name_first_initial]\[login_name].  (For example, for the account johndoe, the path is \\\j\johndoe.) 
    Please check the "Connect using different credentials" box to make sure you can sign in with your CAE credentials.  If you only want to have to do this once, choose the checkbox "Reconnect at sign-in."
Visual of example above in step 4.
5. When prompted for your login name and password, be sure to use your CAE login, with the ENGR domain specified before. It should look like: ENGR\johndoe
Image displaying what the username should look like. See step 5
6. Click "Finish."

Mac OS

  1. From Finder, press Command+K
  2. Enter the path to your directory: smb://[login_name_first_initial]/[login_name] (For example, for the account johndoe, the path is \\\j\johndoe.) 
  3. Click "Connect"
  4. Enter your CAE login and password, with the ENGR domain specified, e.g. ENGR\johndoe, and click "OK"
  5. The drive is now mounted, however it will disappear when you reboot. To enable persistence do the following:
  6. Go to System Preferences from the Apple menu
  7. Click on "Accounts" then "Login Items"
  8. Click the + button to add another login item
  9. Locate the CAE drive you just added, and select "Add"
  10. Exit out of system preferences



The addresses of CAE smb shares are smb:// for CAE Groupspace and smb://<FirstLetterOfCAEUsername>/<CAEUsername> for CAE Filespace. You also need the domain to be ENGR and you will use your CAE credentials

Option 1: File manager

In your desktop file browser (eg. Thunar, Dolphin), use the navigation bar and enter in smb://<servername>/<sharename>.

Depending on which distribution of Linux you are using, you may need to click on "Other Locations" and use the "Connect to Server" field instead of just entering the address into the navigation bar. Example screenshots of both Debian and Ubuntu are included below.


     Debian Server Address


     Ubuntu Server Address

You should get a prompt asking for your credentials. Be sure to specify the Domain as ENGR and sign in with your CAE credentials.  You can choose how long the password will be saved, but we would recommend selecting Forget Password Immediately, as shown in the Debian image below.  Depending on your distribution of Linux, you may need to specify you are connecting as an Authorized User, instead of an Anonymous one.


    Debian Login Info


     Ubuntu Login Info

Option 2: Command line

The following command will mount the filesystem in a sub-directory of /run/user/${UID}/gvfs:

$ gio mount smb://<servername>/<sharename>

Make sure the domain is ENGR, and to use your CAE credentials. You can then symlink that somewhere more convenient ie: $ ln -s /run/user/${UID}/gvfs ~/gvfs. Note that gio mount is not persistent and must be run each time the computer is rebooted.

NOTE: You may need to install packages for the commands to be available, including libfuse3 and gvfs-fuse (for Debian/Ubuntu based machines).

Here is an example of creating a mount:

$ gio mount smb://

You can see how much disk space you have available, and view a detailed analysis of the files in your Unix/Windows home directory, on the CAE My Account page under "Disk Space".

Recovering in Windows

File Recovery in Windows:

The CAE uses a Windows utility called "Previous Versions" which is used for file recovery in case of accidental loss or deletion. To restore from these stored files, follow these directions:

  1. Select the folder where the file used to be. Right-click and select "Properties."


  2. Click on the tab labeled "Previous Versions"

    Previous Versions

From here, there are 2 ways to restores your files:

Option 1: Here, click on the date you want to recover from, and click on "Open."


Then, you can find the specific file you want to restore, right click on it, and click "Undo Delete"

Undo Delete

Option 2: Restore all files from a specific date. Click on the date you want to restore and click "Restore." Another window will pop up asking for confirmation that you want to restore the previous version.


Recovering in Linux

Your CAE files, including your home directory, does periodic "check pointing" and makes snapshots. These are kind of like backups, but don't have version control. They can be found in the .ckpt hidden directory in your home directory.

Steps to restore a file.

  1. Change to your .ckpt directory. The command is cd ~/.ckpt
  2. List out directories using the ls -la command
    Example output of the ls command
  3. Change to the most recent with the desired files. 
    Changeing directory and listing out files in a checkpoint
  4. Copy that file to your home directory. Example command: cp .bashrc ~/.bashrc

Creating a Group Filespace

CAE now offers the option to create your own group filespace on our servers. Students, faculty, and staff with active CAE accounts are eligible to create groupspaces. To check your groupspace quota, and to see all of the groupspaces you already belong to, follow this link.

1.  To create a group filespace, you must first create a group that will have access to the filespace. If you already have the desired group created, you can skip this step. You can create a group by following these instructions.

2.  Once your group is created, go back to the groupspace page.

3.  Click on "Create New Groupspace".

4.  You will then need to enter: A groupspace name, a quota, a directory name (the name of the root folder), and the group to have access. Make sure to enter a quota that is less than the MAX amount remaining.

5.  Click "Submit". It may take our system 5-10 minutes to refresh.

6. You will now need to log out, then log back in for Windows to recognize the new groupspace (Windows only).

Note: Once your groupspace is active, you can access it from the Groups drive. You can map this network drive by following these instructions.

Editing and Deleting Group Filespaces

1. To edit or delete a group filespace, navigate to the groupspace page.

2. You will see a list of all of the groups you are a member of. For groups that you have administrative rights to, you will see links to "Edit" "Change Owner" and "Delete" in the Actions column on the right side of the screen.

3. Click the appropriate link. The "Edit" link will allow you to increase or decrease the allocated quota for the groupspace.  "Change Owner" will allow you to transfer ownership to another user in the group. "Delete" will allow you to delete the groupspace entirely.

4. You will now need to log out, then log back in for Windows to recognize the changes to the groupspace (Windows only).

Note: If you need to modify the group that has access to a given groupspace, please see these instructions: Changing Ownership of a Group and Adding members to a Group
