About this tag
Disk space management on Windows involves understanding where storage goes and how to reclaim it safely. Common culprits include Volume Shadow Copy Service snapshots, which can be trimmed via VSS commands, and hidden files like CapabilityAccessManager.db-wal, which a Windows 11 update addressed. Tools such as NTFS compression and compact.exe help free space without deleting files, while utilities like Fluent Cleaner offer one-click cleanup. Reserved Storage, though disabling it frees space, is best reset via DISM and re-enabled for update safety. Even third-party apps like NVIDIA App can consume significant space. Always back up before making changes, and verify what you delete to avoid losing personal data.

    Free Up Windows Disk Space: Safely Analyze and Clean WinSxS With DISM

    Few things stress you out like a "Low disk space" warning on a 256GB laptop. On many Windows PCs, one of the biggest folders on the C: drive is C:\Windows\WinSxS. It looks too important to touch, and in a sense it is. Windows does include a supported command to shrink it, though, and a new...

    Windows 11 & 10: Stop C: Drive Filling Up by Changing App, Download and Storage Locations

    When your C: drive bar turns red, the usual response is to start deleting things. That works for a while. MakeUseOf's Pankil Shah took a different approach. He had a small C: drive next to a much larger second drive, and he says he spent weeks moving data off C: every time the bar went red...

    Windows 11 Compact OS: Safely Free Disk Space With Compression

    XDA has a new story claiming Windows hides a compression mode that "Microsoft never mentions," and that it freed 38 GB on a C: drive. The feature is real, it's built in, and it can recover a lot of space. The "never mentions" part is generous to the drama, though. Microsoft has documented...

    Windows 11 Point-in-Time Restore Rolls Back Local Files

    A WSL 2 distribution can appear comfortably empty from inside Linux while still occupying a much larger amount of storage on the Windows drive. That is not necessarily a fault in Linux, Windows, or File Explorer. It is a consequence of the virtual disk format WSL 2 uses—and of the difference...

    Windows 11 CompactOS: Save GBs, Not Guaranteed Zero Slowdown

    Windows 11’s compact.exe /CompactOS:always command can reclaim several gigabytes from the operating system’s footprint, but the claim that it comes with no performance cost is stronger than Microsoft’s documentation supports.

    Windows VSS Cleanup Frees Space by Deleting Restore Points

    MakeUseOf’s report that a single Windows command recovered about 11 GB on a nearly full C: drive is technically sound, but its headline leaves out the important part: the space was reclaimed by discarding recovery snapshots. No personal documents, photos, installed applications, or...
