You can overwrite files you have uploaded simply by uploading them again. Be sure to to click the box next to “File already exists. Overwrite?” Of course that won’t work if you typoed the name when you first uploaded it. Just make a list of all the files you need deleted when you’re finished, and submit an LTAC ticket. Please list the full URL to each file on its own line. They don’t need to be clickable links, and they don’t have to have the “http://” at the beginning. I just need them each on their own line.
