Why We Need Partition C Drive

The C drive is where Windows is stored, and you can also keep your files on the local disk; however, you'll be cluttering it. Instead, you can partition your Windows 7 C drive and create additional C drives for each purpose. Such as Local Disk D for storing media files, Local Disk E to store your work files, and so on.

This way, you keep everything organized and also prevent yourself from accidentally deleting an OS file that can corrupt your Windows OS. Also, those aren't the only reasons you should partition your C drive. Here are a few more reasons why you should partition your C drive:

  • Install another OS
  • To set a different file system than Local Disk C
  • Easy Backup Creation
  • Higher Data Safety
