Is hibernation consuming storage?
Hibernation saves your session to disk using a file called hiberfil.sys. On systems with 16GB+ RAM, this can be 16GB or larger.
Is hibernation consuming storage? explained
On Windows, is hibernation consuming storage? happens because of how the system manages files, caches, updates, and application data. Many components silently grow without automatic cleanup, leading to unexpected storage consumption.
- Application data in AppData
- Cloud sync folders
- Windows Update cache and remnants
- Browser caches and downloads
- Hidden system folders
- Game launcher caches

How ClearKun solves it
Instead of showing confusing columns, ClearKun explains every file and folder in plain language. Here is what a typical analysis looks like:
What you can safely remove
- Temporary cache files
- Old downloads
- Browser cache
These files are always safe to remove and will be recreated when needed.
- Application-specific caches
- Old log files
Verify the application is not actively using these files before removing.
- Currently open documents
- Active game save files
Removing these may cause data loss or application errors.
- System32 folder contents
- WinSxS folder contents
- Pagefile.sys
- Hiberfil.sys
These are critical Windows system files. Deleting them will break Windows.
