Why is my E drive automatically filling up?

The E drive is a recovery drive that lets you store files needed during an emergency recovery, like when your system is unstable. It is a partition on the main hard drive, with less space than the local C: drive.

  • File storage – If you store files in a recovery E drive or a backup program uses it to store files, it gets full quickly, which can cause problems when you want to use the system recovery function.
  • OS threshold – Windows has drawn a 200MB threshold line for optimal performance; it takes automatic actions to maintain minimum performance capabilities below this. For example, if it goes below 80MB, you’ll get a strong warning message as the system tries to free up drive space.
  • Presence of malware – For computers exposed to malware, you can expect different erratic behavior. Automatic filling of the E drive is an example, and users will have to do a PC scan with a reliable antivirus.

To resolve the E drive low disc space warning, there are some fixes you can perform to get some free space back.

One of them is first to find out how much space is in your operating system and what data or apps are taking up space, then decide what to remove or delete.
