No it dose not delete all your files. It deletes the registry error files, and you internet catch files. That's it, its a trusted and pretty good program to use.
No, the Disk Defragmenter does not delete any files. The defragmenter rearranges the existing files on the hard drive so they are contiguous, rather than scattered around your hard drive in multiple pieces. The software that deletes temoporary files and what not is called Disk Cleanup.
No, it is not good.
No, rebooting does not delete your files.
Contiguous: Immediately adjacent. For example, contiguous sectors on a disk are sectors that come one after the other. Frequently, a file stored on disk can become fragmented, which means that it is stored on non-contiguous sectors. taken from http://www.webopedia.com/TERM/C/contiguous.HTML So one could assume that the difference is that contiguous files are files that are stored immediately adjacent from one another (together) and non-contiguous files are not stored adjacently hence are separated or scattered. Hope this was of some help.
No
If you run Install then Repair it shouldn't delete files in "My Documents" (at least it didn't when I did it recently). If you run Install then Install it will delete the files.
go to search all files; type mmview* delete both files there are 2 of them, that should do it. If they go into your recycling bin delete them. But they may not show up there, and that is good
no is there a software to delete it
You can delete it all, they are temporary files.
Most of the time, yes but i strongly recommend that you use a PC cleaning program to delete teporary files. you can find tons of free cleaning programs online. I use ccleaner, but any program that can delete tempoirary files is good.
