Removing one file type from a sub-directory
Via the command line
To delete one file type from the entire hard drive, or from one subdirectory: sudo find / -name “.DS_Store” -depth -exec rm {} ; The first / can be replaced with the full folder path.
.DS_Store can be replaced with any filename, or wild card, *.jpg for instance

These two commands are used to check disk usage
