Hide / Unhide a file is not working so well

Question

I used this to hide the file:

File.SetAttributes(path, File.GetAttributes(path) | FileAttributes.Hidden);

But when I wanted to unhide that file, the file just got deleted, but in the code I didn't get any error, so the file is still there.

File.SetAttributes(path, File.GetAttributes(path) | ~FileAttributes.Hidden);

To disable a single bit you need to use `& ~`, not `| ~`. Look for examples in the linked question. If something doesn't work for you, please, update your question with necessary details. — default locale, Apr 28 '17 at 12:18

MSDN:

var attributes = File.GetAttributes(fi);
if ((attributes & FileAttributes.Hidden) == FileAttributes.Hidden)
{
    attributes &= ~FileAttributes.Hidden;
    File.SetAttributes(fi, attributes);
}

You can make a simple check with

bool b = File.Exists(String path)
