How to resolve: files which are visible in Terminal, but invisible in the Finder? In Yosemite v10.10.3, I am trying to reinstall Skype, as it does not sign-in at all, following this link. In order to do so, I need to move some files and folders to trash as to totally uninstall Skype first. However, I cannot see these files and folders in the Finder, although they are visible in the Terminal !!

I've also tried the following two commands:

:...&amp; defaults write com.apple.finder AppleShowAllFiles YES
:...&amp; killall Finder


The result is that I see many hidden files among which I cannot find the files and folders I am looking for.

Please help me with any of them: Skype sign-in problem or Finder Invisibility !!
Be sure you aren't looking in the root library, but your user library. Skype in Application Support and com.skype.plist are not invisible by default. Try changing the ~/Library/Application Support with /Users/&lt;username&gt;/Library/ Application Support, with  being your Username without the &lt;>. 

I find it easy to "Go to" with Shift+Command+G while there is Finder selected, and in the path type /Users/&lt;username&gt;/Library/Application Support/ and click Go. Then look for Skype. To find the plist, do the same, but with Preferences.

Also note that in terminal, the path to Application support would have a backslash (/Application\ Support), instead of only a Space
