Reordering files using NSFileManager on iPhone

Question

I have a question on the NSFileManager.

I store a collection of images in the Documents directory in an iPhone app.

basically they are stored as img0001.jpg, img0002.jpg,...img0010.jpg.

I am using a table view to show a list of these images ( I loop through the directory and put them in an NSArray to show in the table.), but I would like to allow the user to re-order these. I wanted to rename the image based of where they moved it in the UITableView.

So if they move img0008.jpg to row 5, it would become img0005.jpg, and everything underneath it will be renamed to 6,7,8 etc...

I was curious if anyone else had a need to do this? If so, how did you attack it? I think it is something that is very possible, I am just hitting a wall at the moment.

If I solve this before someone replies, I will make sure that I post my solution.

Thanks

You can always create an array of the files and order them in the array, then display the re-ordered array of the directory contents.
