What Is C Drive for on Windows 10 or 11 Computer

Modern hard disk drives have large storage capacity; you can divide them into any number of partitions C, D, E, F, etc.

Most users use C Drive to store Windows operating systems and different applications. The functions of D Drives vary from computer to computer.

C Drive is an essential part of your computer known as a hard disk drive. It is responsible for storing your computer's operating system, applications, and all files you download from the internet.

Everything you install on your computer is stored in C Drive. Even when you turn on your computer, it sends a signal for booting to C Drive.

Why Do You Backup C Drive to OneDrive

Users used to back up the C drive to an external hard disk. But nowadays, it is preferred to back up C Drive to OneDrive.

OneDrive is a cloud storage service by Microsoft to store and sync your valuable information anywhere, anytime. It is a fantastic way to protect your valuable assets from cyber-attacks and any loss due to hardware damage.

Backing up C Drive to OneDrive has many advantages:

  • One drive is a cloud storage service that will back up your data without plugging in an external hard drive.
  • It is safe to use. Don't worry about hardware failure or crash.
  • Easily accessible, you can sync folders and files anywhere in a few seconds.
  • In contrast to external hard disk drives, it is more affordable.

Can You Put an Entire C Drive on OneDrive for Backup and Sync

You cannot. OneDrive is only for backing up or syncing files and folders associated with your user account. You need to look up more information about the OneDrive backup limits. But with EaseUS Todo Backup, you can choose everything on your computer to back up.

Before starting the Backup of your C Drive to OneDrive, you must know that OneDrive is exclusively for storing important files and folders.

OneDrive personal cloud storage is 5GB. When you set up OneDrive, it automatically syncs all your files, including documents and photos, to the OneDrive cloud.

If you don't want to sync all files, you can sync specific files and folders, such as your important documents, pictures, and system files.

Make sure that storage space is enough for all the files you want to backup. Chill out! If it's not enough for your system's files, you can grab a Microsoft Office 365 bundle.

Microsoft Office 365 bundle has a storage capacity of 1TB. If it's too much for you, then you can grab storage of 100GB for $2 per month.
