I lost my work space, how can I get it back?

Somehow I lost my work space, so I cannot select any files I had made before.

Here is only Explorer: User

Can anyone help me?

Hi @a27fcc3fd9e943a7,

Thanks for contacting us and welcome to the Community!

Sorry about this issue. Did you delete something? There should be a catkin_ws folder listed, unless it was removed after launching the course.

In any case, just come back and launch the course after staying off the system for 20 minutes or more. Then let us know if you cannot find your previous files. We’ll try to recover a previous version of the files for you.
