Furthermore, the space used by the page file (usually managed automatically) is negligible on modern drives. Saving 4GB or 8GB of space on a 1TB SSD is rarely worth the risk of system instability.
After restarting, the old pagefile.sys will be gone (or moved). Windows will use the new location or run without a pagefile.
Generally, . Here’s why:
| Action | Possible? | Recommended? | Consequences | |--------|-----------|---------------|----------------| | Delete pagefile.sys while in Windows | No | ❌ | File is locked; can't delete. | | Force-delete via recovery media | Yes | ❌❌ | Windows recreates it or crashes. | | Disable paging file entirely | Yes | ⚠️ Only for advanced users with >16GB RAM | Risk of out-of-memory crashes; some apps may fail. | | Move to another drive | Yes | ✅ Good | Frees space on system drive; no performance loss. | | Reduce its size | Yes | ✅ Good if you have spare RAM | Less virtual memory available; still safer than disabling. |
When your computer runs out of available RAM because you have too many programs or large files open, Windows moves less-frequently used data from the RAM to the pagefile.sys on your drive. This frees up your fast physical RAM for the active tasks you are currently working on. When you switch back to the older task, Windows "swaps" that data back into the RAM. Can I Delete Pagefile.sys?
