I recently set up MX Linux on my USB and now I want to make a specific folder (my Windows user folder) read-only. Initially, I had changed the permissions to allow writing, but now I need to revert that for backup purposes. What's the best way to do this, particularly using Linux commands? Just to clarify, I don't need this anymore, but I'm curious about the method.

If it’s a Linux filesystem, change the folder's owner and permissions to root, then grant your user read access. This way, you can safely back up your files without altering anything. Definitely check out how Linux permissions work since understanding this concept will help you manage files better in the future.
You can use the `chmod` command to modify the permissions on that folder. Just open your terminal and type in `chmod -w` for the folder to remove write permissions. If you need it to apply to everything inside the folder as well, use `chmod -R -w`. This will make the folder effectively read-only!
You can access your Windows partition directly from Linux and copy the files over if that’s what you need for your backup. Just make sure you're doing this while your system's mounted correctly so you don't run into permission issues.
Another approach is to adjust the mode bits for the folder using `chmod`. It’s a bit more advanced but definitely worth learning. Be careful with permissions, and maybe check your current permissions with `ls -l` before you change anything for a reference. Also, you can mount the file system in read-only mode if you're looking to ensure nothing gets altered.
