Several unfamiliar files in common directors that can only be seen via the command line.

While browsing directories using the command line, I found many weirdly named files with common extensions. You cannot see these files in the file explorer even if you check "View Hidden Files".

These files repeat in many common locations, e.g. User/username, Documents, Downloads, etc.

Has anyone else seen these or similar files that don’t show in file explorer?

Here are some of the files I found.
