Can I safely delete folder $GetCurrent in Windows 10?
Sim.
What Is $GetCurrent?
The $GetCurrent directory is created during the upgrade process. It contains log files about that last Windows upgrade process and may also contain the installation files for that update. On our system, the $GetCurrent folder took up 3.38 gigabytes after upgrading to the Creators Update. This is because the folder contains leftover Windows Update installation files.
Assuming you don’t need to review the log files stored here and you’ve finished installing the latest Windows Update, this folder is safe to remove. In theory, Windows should automatically delete these files itself after 30 days at most. In practice, we noticed that this folder was still lying around more than a month after upgrading to the Creators Update, so we had to delete it ourselves.
No entanto, ao contrário do que se pensa, o utilitário interno de limpeza de disco não o elimina:
The Windows Disk Cleanup tool doesn’t automatically delete these folders. However, it does delete the $WINDOWS.~BT and ~WINDOWS.~WS folders you may also see in your C: drive.
To get rid of these folders, you can just delete them the old fashioned way. Select the folders in File Explorer, right-click them, and select “Delete”. File Explorer will prompt you to provide administrator permission to delete them, and you can then empty your Recycle Bin to free up the space they take on your device.
Deleting these folders won’t cause any problems if you don’t need to review the log files they contain and if you aren’t in the middle of installing a new update to Windows. Even if Windows does need the files to install an update, it will just download them again.
