Caution for Long File Names
Most backup tools, including Windows Explorer have a hidden flaw. They can scramble the "short file names" for your files. It doesn't matter at all for your data (documents, financial records, pictures, email, etc.), but if it scrambles the short file names for any system or program files that you try to restore, they just won't work. Windows will find the wrong file when it goes looking. This is not a big deal for most users, because they rarely back up system or program files.

A short file name will be different from the corresponding long file name if the file name is too long to fit the dimensions of the "8.3 format" -- 8 characters for the name and 3 characters for the extension (thanks Bill Gates). Otherwise, they're the same.

Suppose your original files were: [program file1.dll, program file2.dll, program file3.dll] Notice that the file names are longer than 8 characters. The short names might be (in the same order) [progra~1.dll, progra~2.dll, progra~3.dll]. If you restore them the long file names will be just the same as before, but the short file names can get scrambled. They might come out in this order [progra~1.dll, progra~3.dll, progra~2.dll]. For example, 2 has been swapped with 3 for the third file.

The "Backup" program that comes with Windows 98, and "Windows Backup" (NTbackup) that comes with Windows XP do not have this long file name problem.
