I am also having the same issue. I delete a drawing and the number of drawings I have goes down by one, but the drawing I selected didn't disappear. Plus it is very tedious to delete a mass amount of drawings. The program has started to run slow since I hit over 100. About a month and a half ago.

Sorry to hear about the issue. 600 is many plans. However, I am delighted to know that the app has been so useful to you!
I think the easiest way to copy the plans would be to plug the iPad / iPhone into a computer, go to iTunes > Select your iPad > Click Apps > Scroll down to File Sharing, and find Floorplans. I've attached a screenshot. Once you locate the files, you can just drag them to your desktop, or a folder.
Also for such a large number of files, I'm sure there are ways we can avoid the lag. I'll raise this with the devs, and see if there's a solution we can implement in a future update.
