I installed Paretologic to clean up my PC of unwanted junk files. When I clicked on clean it went to my external hard drive and erased my music collection. It completely wiped out approximately 15, 000 songs and albums that took me years to compile. Some songs on that hard drive were hard to find and were very rare. Additionally, my computer no longer reads my external hard drive as added hardware. Buying and using this product could cost you more than you are willing to spend. At $.99 a song to download off the Internet this was an expensive mistake. I would also add that this company is next to impossible to contact by phone. read full review »
