Question 1. What Is "Low Disk Space" Warning in Windows

Windows created the low disk space warning to alert computer users when their hard drive is running low on available disk space.

To free space on this drive by deleting old or unnecessary files, click here."

Question 2. Does Low Disk Space Affect Computer Performance

200 MB is the threshold line which takes the most response to Windows optimal performance. Once your disk falls below this threshold, your system automatically takes actions to maintain minimum performance capabilities.

1. When Disk Space Falls Under 80 MB

Windows delivers a stronger warning message, and then it starts to free up drive space by deleting previous System Restore points. This reduces the number of restore points you can select from to restore your computer if the hard drive is impaired or corrupted.

2. When Your Drive Falls Under 50 MB

  • When this occurs, an urgent warning message is delivered every four minutes, until the user takes actions to free up disk space.
  • If you ignore this warning, then Windows will purge the ALL System Restore points, and suspend the System Restore function.
  • System Restore will not be reactivated until 200MB of disk space becomes available on the system drive
