...we have a number of clients in the video industry who post video clips that are typically labeled with #...... We tested some uploads such as File #37.mov or File #37.png. The files passed successfully if the "#" was removed. Unfortunately, we cannot guarantee what a client will do. Can anyone recommend a solution other than telling them to mark it out prior to upload?
