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 :(

You shouldn't need to see hidden files or system files. I only use "Show extensions". I've never downloaded an archive with hidden files, and even if I did I'd just turn on Hidden files for as long as it takes to fix that situation. The window statusbar says stuff like (3 files and 1 hidden) so you can tell anyway.

I'd much rather see a nice clean drive root than see ~$SystemRecycleBin or pagefile.sys or whatever.
