When you get E drive low disc space notifications on your computer, which usually appear periodically in desktop view or while trying to open your recovery drive, it could be that the drive is full and you can’t store any more files on it.

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 available space than the local C: drive.

If you store files in 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.

This is why you shouldn’t store files in there, except those related to a system recovery.

Windows has drawn a 200MB threshold line for optimal performance, so when your system falls below this, it takes automatic actions to maintain minimum performance capabilities.

If it goes below 80MB, then you’ll get a strong warning message as the system tries to free up drive space by deleting restore points.

But if it goes below 50MB, it self-preserves and this is when you get urgent warning messages saying E drive low disc space delivered almost every four minutes until you free up some disk space.

In order 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 to first 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.
