Hidden files (all of them) on my computer don't show although I choose "Show hidden files and folders" and "Hide protected operating system files" in Tools -> Folder options.
When I come back to Tools -> Folder options -> It's still in "Do not show hidden files and folders". I don't know why.
I had scanned for viruses and spywares but I didn't find anything.
Thanks for reading. Please help me.

Welcome to PCHF khongten!

Are you using an administrator account when you make the change? If not try using an admin account and report back what happens.

Yes, I'm using administrator account but It still doesn't show my hidden file.

Hi khongten, once you've selected those 2 options, select 'Apply to all folders'

close the window, and reopen it.

It doesn't work.

Maybe the folder has no hidden files.
If you remember the folder/file name, you can try typing it into the address bar.
Try doing a search and checking the box "search hidden files and folders"
