NirCmd is a small command-line utility that allows you to perform various system tasks easily. If your C drive is full, you can use NirCmd to free up space by deleting unnecessary files, clearing temporary files, or managing system resources.
Here are some ways you can use NirCmd if C drive is Full:
1. Delete Specific Large Files or Folders
You can delete specific files or folders you no longer need, for example:
nircmd deletefile "C:\Path\to\file\or\folder\*"
Note: Be very careful with delete commands to avoid deleting important system files.
2. Automate Cleanup Tasks
You can create scripts that run cleanup commands automatically to free space regularly.
3. Clear Recycle Bin
Emptying the Recycle Bin can free significant space:
nircmd emptybin
