DIFFICULTY FINDING A HIDDEN CLEANER THAT WILL WORK WITH YOSEMITE

I used to own an older Mac, a 2010 Mac to be exact with the disc drive in the side of the computer.  I downloaded HIDDEN CLEANER to get rid of junk files that showed up when I transferred music to my Sansa Clip +.  This Hidden Cleaner worked very well.  I now have a new 2015  Mac with Yosemite Operating System, and the old Hidden Cleaner will not work.  Can anyone recommend something that will work with my new Yosemite Operating System.  I have put over 1000 songs into this and would like to add about 500 more however, I am stuck.

Please help.  Anyone. 

I was only aware of Hidden Cleaner and KopyMac, the latter of which I believe disappeared a bunch of years back . . . .

For automated tools, I was only aware of Hidden Cleaner and KopyMac, the latter of which I believe disappeared a bunch of years back . . . .   Hopefully, some Mac folks will have other suggestions.
