File Deletion

Sometimes, files just don't want to go. They cling on to dear life. Generally, you would use the following command to delete files: 

erase [filename]

However, sometimes Cisco IOS will spit back an error if it doesn't want to delete said file, for whatever reason. If you run into an issue, use the following command: 

delete [filename]

If that doesn't work, usually with the "Is a directory" error, use the following command to force the deletion: 

delete /force /recursive [filename]
