  • Press the Windows key + S on your keyboard and type "Disk Cleanup" in the search box. Select the Disk Cleanup app from the search results.

  • Once the scan is complete, the Disk Cleanup window will open. Check the boxes next to the files that you want to delete. Windows will provide a brief description of each file type, so you can make an informed decision about what to delete.
  • Click on the "OK" button to confirm your selections.
  • A message will appear asking if you're sure you want to permanently delete the selected files. Click on "Delete Files" to proceed.

Windows will delete the files and free up space on your hard drive. This may take a few minutes depending on the number and size of the files that you selected.

#2 Remove system restore points

Windows periodically back up the system and these backup files will use some disk space. All backup files, excluding the most recent restore point, can be deleted. Don't worry, it's safe to delete the old restore points since even if the system malfunctions, you can still restore the computer to the most recent functional state.delete restore points

#3 Move program files from c to D or another drive

Moving program files from the C: drive to the D: drive can be a bit tricky, as simply dragging and dropping the files may not work, as the programs may be dependent on other files and settings stored on the C: drive.program files

Here are the general steps you can follow to move program files from C: to D:

  • Create a new folder on the D: drive where you will move the program files.
  • Uninstall the program(s) you want to move from the C: drive. This will remove the program's files and settings from the C: drive, but leave any shared files and settings intact.
  • During the uninstallation process, you may be given the option to choose a new installation path. If so, select the folder you created on the D: drive.
  • If you are not given the option to choose a new installation path during the uninstallation process, you will need to reinstall the program(s) on the D: drive. Be sure to select the folder you created on the D: drive as the installation path.

Once the program(s) are installed on the D: drive, you can delete any leftover files on the C: drive.

It's important to note that not all programs can be moved to a different drive, as some may have dependencies on the system drive. In addition, moving programs in this manner can be risky and may cause unexpected issues, so it's always a good idea to back up your data before attempting to move anything.

  • Hidden files
  • Corrupted disk or file system
