Folder is no longer in this location? But Folder Still There

Question

I have Windows 7 and PrE 9. I was working on a folder/project on an external drive and had no problem accessing the avi or other folders in the drive. Once I was satisfied I no longer needed the project (about 14 GB) I deleted the project. I got a pop up window saying the folder was no longer in this location. What the heck? I was just working on it. I checked the folder again, everything was still there and functional. I then tried to cut and paste the folder to my main drive to see if I could delet it from there.
It started out as a normal transfer of files and then gave the message that the folder being transferred was no longer in that location. Ok. I rechecked the Project folder and it was still there but....All of the folders inside were gone except a Stop Capture folder of Zero bites. It still says the folder isn't there lol. Even though it says Zero bites I would like to get rid of this folder and the stop capture folder inside. I had two other projects right next to the one still there and they deleted fine.
Is this a Windows 7 thing and have you guys had this happen? I have one other folder on my desktop from a couple years back with the same scenario. Says its not there so I can't delete it. I just labeled it "can't get rid of this folder" and gave up but it still bugs me. Now I have another one.
Thanks

ATR,
I should have labeled this post "Could Not Find This item" or Item Not Found
Problem solved. I downloaded 7-zip version 9.22 beta from sourceforge (for whatever reason- just seemed good) There are other places to download from. Choose your favorite.
Here is a screenshot of my problem folder so that if others run into this problem 7zip may work for them.
I had a tussle with 7zip and it did not work to begin with, but the problems turned out to be really simple. My nephew is a computer wiz and came over to use the DOS procedure that people are using on the internet to delete the folder. At first he couldn't get it to work. Then we discovered there were 3 folders, one inside the stop motion capture, the stop motion capture, and the outer project folder. The folders had to be deleted from the innermost first, one at a time, to the outer folder. Hallelujah. This folder is gone after 2 years of staring at me.
If you have this message like I did the first thing to do is go into the main folder to the innermost items and delete as many as will delete normally thru windows. Keep deleting the inner folders til you get to the first one that won't delete. Then see how many folders inside the main folder remain.
So let's try 7zip again. I am a newbie so I thought others might like how my nephew and I did it.
In the main window there will be a short list on the left starting with computer and accessable drives. Double click on computer (or whichever location your trouble folder is in). A bigger list of stuff will show up. Mine was in the desktop so I double click on that. I look at that list fo find my trouble folder. Double click on that. Each time you double click will go to the next internal folder. Then when you get to the innermost folder rename it ( we just used the word del). Up higher on the screen is the red delete X click on that. the folder will be gone. To get to the next folder use the green "up one level" arrow just to the left of the url bar. The next folder will show up, rename and press X to delete. When you have reached the outer folder which you thought was your problem folder it will dissapear from your desktop ( or wherever it was located). In my case I had to delete 3 folders. My other problem folder was in my external drive so I just went through the same procedure after double clicking on the drive letter which was in the list in the starting window. Exit 7-zip when done.
You don't have to close 7-zip to delete the folders as I listed in my previous posts. These were just info I got from a couple of websites. Not complete by any means. They presume you know what you are doing with computers.
The only reason I started this discussion was because both of these folders were made with PrE7 and PrE9. I have never had this problem with anything else. Must be some kind of filing error between PrE and windows.
Hope this helps. The DOS procedure was lengthy and was way above my head but 7-zip only took a few minutes.
