Body
There are two main locations for how to access and save files from WSL:
CAEN Home Directory
To access your CAEN home directory, you will need to log in with your UMICH password when prompted in the pop-up window:

You will then be able to work with your personal Linux files and data after running the WSL Terminal as user (will not work for root):

To access the default location where Linux files are stored in your CAEN home directory, use the following command, where uniqname is replaced with your U-M uniqname:
cd /home/uniqname
If you wish to also access the Windows files stored in your CAEN home directory, you can change locations using:
cd /mnt/n/windat.v2
If you didn't type your password correctly or there is some other issue with your access to your home directory, you can click the "Reboot & Remount" shortcut and log in again:

C: Drive
Note: Files stored locally on the computer's C: drive are completely temporary, and not saved to the network. If you wish to save or store files for future use, using your CAEN home directory (/home/uniqname for example) is recommended.
The computer’s C: drive is automatically mounted to the path /mnt/c, and temporary space is available to individuals in /mnt/c/Users/uniqname, where uniqname is your personal U-M uniqname.
To access your temporary space for working with files, use:
cd /mnt/c/Users/uniqname
