I just downloaded CCleaner and have so many corrupt files. IF I chose Wipe Free Space, will that actually delete any files in my reg or other valuable files? I have been writing a book for over 8 years and lost the backup file. I used Recuva and tried to recover the files, however, they are now corrupt. I cannot find my book and want to clean up all of the Free Space, however, a bit nervous about doing that. I do not want to create more problems on my computer. Any suggestions? Thank you ~
