Student Storage Allocations

  • When using the CAEN Lab Software Environment (CLSE), files saved to the Desktop or Documents folders are stored in your Windows Home Directory, which can be accessed directly via the N: network drive.
  • The CLSE also saves many environment and application settings to your Windows Home Directory.
  • Regular snapshots are taken to enable easy file recovery.


Students receive a 50 GB Windows Home Directory when they are granted a full CAEN Account to support their use of the CAEN Lab Software Environment (CLSE). Files saved in student Windows Home Directories are available in the same location on all CAEN lab computers. Program settings that are saved on one CAEN lab computer will also be available on all other CAEN lab computers.

Even though other storage options are available to students (such as Google Drive, Box, and portable storage devices) the CAEN Windows Home Directory provides an easy to use and consistent way to save and access files on CAEN lab computers. Student storage allocations provide space for students to perform work in their courses and maintain course content from term to term. Students can take advantage of the larger Google Drive and Box storage by copying older or less-frequently used files from their CAEN Windows Home Directory to those services.

Many environment and application settings you change will follow you from one CAEN Windows computer to another, enabling you to work quickly and efficiently with a consistent user environment. Roaming Profiles are reset at the beginning of each Fall term, in conjunction with the release of the new CLSE.

Student storage allocations cannot be increased.

Roaming Profiles

In the CLSE for Windows, when you change settings in many software applications, those settings will remain set when you use a different computer. The technology that enables this is called a Roaming Profile.

All computers running the CLSE for Windows use Roaming Profiles instead of locally-stored user profiles. Roaming Profiles allow users to begin working quickly because they are not required to reset their environment each time they log in. Your Roaming Profile stores the files in your Windows Desktop and Documents folders, as well as many of your application settings.

Do not delete the windat.V2 or profiles folders; these are essential for the Roaming Profile.

The windat.V2 Folder

A folder named “windat.V2” resides in every Windows Home Directory. Several important folders are redirected to the windat.V2 folder, including the Desktop and Documents folders. Files saved to your Desktop or Documents folders count against your quota, because they are stored in your Windows Home Directory. If you go over your quota, you may have trouble using the CLSE for Windows.

Do not delete the windat.V2 folder.

The profiles Folder

When you first log into CLSE for Windows, your profile is created in a folder called “profiles” in your Windows Home Directory. When you log out, the profile is saved in this folder. The following folders make up your profile:

  • AppData – Application data and settings
  • profile.V2 – Windows environment settings; contains hidden files: ntuser.pol, ntuser.ini, and ntuser.dat
  • Start Menu – Customizations to the Start menu

Do not delete the profiles folder.
