Troubleshooting Disk Space Issues on Windows 11: When ‘Other’ Takes Up Unexpected Storage
Many Windows users encounter perplexing storage discrepancies on their drives, especially when the available space doesn’t align with the files they recognize. This article explores a common scenario: a secondary drive showing significant space allocated to an unrecognized “Other” category, despite having minimal visible files. We’ll examine potential causes and practical solutions to regain control over your drive space.
Scenario Overview
A Windows 11 user recently observed that their 375GB secondary drive (designated as drive E:) reports only about 20GB free. The drive primarily hosts a large game installation, ARK: Survival Evolved, consuming approximately 140GB. However, detailed drive properties reveal around 202GB labeled as “Other,” with no apparent folders or files visible when attempting to explore this space.
Key Details
- Operating System: Windows 11
- Drive Type: Internal secondary storage
- Primary Concern: Discrepancy between visible game files and the “Other” storage occupying most of the disk space.
Understanding the “Other” Storage Category
In Windows, the “Other” category in disk properties often encompasses:
- Temporary files and cache: System or application cache that isn’t visible via File Explorer.
- Hidden files or system files: Files marked as hidden or system-protected, not visible by default.
- Residual or orphaned files: Files left behind after uninstallation or incomplete deletions.
- Drive corruption or filesystem issues: Corrupted file structures that misreport space.
When users attempt to explore this storage space via Properties → Details, the system may be unable to display specific files or folders, indicating potential corruption, system reserved space, or other underlying issues.
Step-by-Step Troubleshooting
1. Use Disk Cleanup and Storage Settings
Start with built-in tools:
- Disk Cleanup: Search for “Disk Cleanup” in the Start menu, select the drive, and clear temporary files, system cache, and previous Windows installations if applicable.
- Storage Settings: Navigate to
Settings>System>Storage. Enable “Storage Sense” and review what kinds of files are consuming space.
2. Investigate Hidden and System Files
Ensure file explorer settings reveal all files:
- Open File Explorer.
- Go to the View tab.
-
Check Hidden items.
