i just downloaded the latest updated version of ccleaner from filehippo.com, i installed in my com and as usual checked all the options i tried error fixing, usualy if the error fixer shows lots of error i go for another error check which usauly comes with new i/o errors, usualy am confident with ccleaner i dont back up. but i think the new version has some bug to be fixed in the error fixing catog. cause many of my desktop items converted to .ink not able to rectify. is there really a bug or its due to my stupidity. pls some one answer.if possible give solutions
