I think only the Europe versions will, but backup all your important files anyway.
Also, if you are using the Europe version remember to backup a web browser.
No. All of your previous files can be found in the C drive in a folder called "windows.old".
BEFORE you re-install Windows - it's absolutely vitalthat you copy ALL your personal files to disk (or other storage media). Re-installing Windows will wipe your hard-drive of all its data before the program re-installs all the necessary bits that it needs ! If you didn't back-up your files before you do the re-install - you have lost everything !
All windows files can play on a Mac if you run boot camp (which is bascially installing windows on your mac) if you want to run windows files on a native AMc operating system you must have the program installed for the mac version. For example, if you have Micrsoft Word for Mac then you can view files like .doc or .docx on your mac. Same with .wmp, you need window's media player installed on your mac. Hope this helps.
All the files under C:\Windows, which is what contains the OS.
Updating iTunes overwrites all previous versions but music, apps and other data doesn't get changed.
This is possible. You could backup all your important files, install windows 7 then restore all your files. You won't be able to migrate applications when you are downgrading

No, it is not safe to remove the I386 Files from your windows XP Computer. Because with out those files your computer would not be able to function proporly. It needs those files to run Windows XP.
You need to change your Windows Defaults. This option is found in the Control Panel. You can choose which program to open files with by default. It sounds to me like all your files have a Windows Media Player Default setting on.
All types of files that can be read and copied.

The Recycle Bin. Windows keeps a special folder, for each disk, for the deleted files; if you open the "Recycle Bin", Windows will show you the deleted files for all connected drives.Note that Windows keeps only a certain number of MB of files for each drive; once that is passed, the oldest deleted files are eliminated permanently, when additional files are deleted.
