Several users have recently complained about an issue regarding their storage not adding up in Windows 11. To some, it feels like the system’s storage on their hard drive suddenly vanished.

If your Windows storage usage settings is misreporting files by a huge amount, take your time to explore this article to troubleshoot the issue.

Why doesn’t storage space add up?

There is almost no straightforward cause for this. However, you may have hidden files and directories that contain system files unaccounted for in the calculation. Other probable causes are:

  • Too many tiny files stored on disk – Small files take up more space on the disk than the initial size. They occupy the initial size and take a chunk in the file system to save names and properties. Hence, these may be unaccounted for.
  • Unaccounted files in Recycle bin – If you have too many deleted files, they are stored in the Recycle bin. Hence, they are hidden and may cause a disparity in storage space.
  • Content indexing takes up space – Allowing files on the drive to have contents indexed in addition to file properties may create an unaccounted space on your device.
  • Enabled System Restore points When enabled, it creates new files regularly whenever updates are installed, and this consumes a large chunk of storage space, which may be unaccounted for. This may also cause Windows to be slow after Windows Restore.

Although the causes are not only limited to these, let’s explore the possible ways to troubleshoot the problem.
