Extracted Winrar files do not show on HD

ok so i downloaded an ost off BT, but when i extract it to any particular folder it does not show on explorer, but takes space. after extraction i also hear a chime.

the wierd thing is, even if i cant extract it, i can double click the file and play it in media player. wtf?

the ost comes in two volumes. one includes wierd moonspeak and one doesnt (it is all in one RAR) the one without moonspeak extracts fine. :((

the one with the moonspeak is the one with all the good parts!
its the mai hime ost :(

As a sanity, security, and decency measure, show hidden files and folders, show all files (as opposed to hide system files) and do not hide extensions should be be the first thing you do after installing Windows.

As a sanity, security and decency measure, the guy at Microsoft who decided these options should be set that way by default or they should even exist should be put out of his misery.
