    Great tips as usual, especially about what files to backup. The tip about the Application Data folder is really helpful. I don’t know why MSFT hides it.

    I read the “What Files Should You Backup on Your Windows PC?” and have a question. What if you put your files in a shared folder? Should somthing happen to your computer, other computers can access your files, correct? Meaning they can still be put back on a computer?

    ahhh, you’re a Deftones fan! very nice!

    @Adamboy7:

    If you’re accessing shared files, they’re still physically located on one computer. If the drive holding those files crashes, they will not be available to any of the computers accessing the files remotely. You can access these files if “Offline Files” is enabled on your computer, but the sharing system relies on you being able to access the hard drive physically hosting the shared files.
