It is pretty standard for your Windows computer to run out of space. After all, we only have so much drive space to store our important data and files. We must clean up our drives regularly to make more space for more files. 

There are two ways to increase storage space, especially in the C Drive. The first is to run clean-up tools to delete whatever is not required. Second, add more storage. While doing the former is easy, the second will take a lot of effort. You will have to move the OS to a new drive and make sure the C Drive on the new drive has enough space. 

Additionally, when formatting the older drive, you will need to ensure no chance to recover data from it. You will need to wipe the drive using professional software to wipe the entire driver and remove all the data. Ensure you have a backup of the drive you plan to wipe so any essential data is not lost forever.
