[Sean Lee] "Ahh, you nailed it! It's my work flow. I've been backing up the cards and working off of a hard drive, keeping the file structure intact when I should just be importing them"
Yea, that doesn't mean that you shouldn't back that folder up to an external drive once imported so that you have an off-line backup but there is no reason to keep two copies on your editing hard drive.
[Sean Lee] "I was worried that if anyone else did the editing with a different program that they would need the file structure, but I guess not since the files get neatly put into a folder."
Well... if that's a concern, you might want to backup the cards file structure to the external drive so that you could copy it back out and give it to someone else to edit. The people most affected by this would be Final Cut Pro editors because FCP doesn't do well with native formats and likes to ingest everything from the cards and convert them to it's own proprietary ProRes422 format.
