默认的桌面和用户文件都是C盘，每次重装系统要备份，为了方便可以把它设置到其他盘符，一种方式是通过一些软件功能，如360有一个C盘搬家，也可以修改注册表文件：
Windows Registry Editor Version 5.00 [HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerUser Shell Folders] "Desktop"="E:\Documents\Desktop" "Favorites"="E:\Documents\Favorites" "My Music"="E:\Documents\Music" "My Pictures"="E:\Documents\Pictures" "My Video"="E:\Documents\Video" "NetHood"="E:\Documents\NetHood" "Personal"="E:\Documents\Personal" "Startup"="E:\Documents\Startup" "Start Menu"="E:\Documents\Start Menu" "Templates"="E:\Documents\Templates" "PrintHood"="E:\Documents\PrintHood" [HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerShell Folders] "My Video"="E:\Documents\Video" "My Pictures"="E:\Documents\Pictures" "Desktop"="E:\Documents\Desktop" "NetHood"="E:\Documents\NetHood" "Favorites"="E:\Documents\Favorites" "Start Menu"="E:\Documents\Startup" "My Music"="E:\Documents\Music" "PrintHood"="E:\Documents\PrintHood" "Startup"="E:\Documents\Startup" "Personal"="E:\Documents\Personal" "Templates"="E:\Documents\Templates"
