I have been testing the current D703 file system. I was able to create and dump over 35k files in the images folder and it is still working, although I must admit things have slowed down a lot when creating the image files. so if there is a 32k file limit, it has been surpassed and things are still chugging along. But only a demo site for testing is being used, so no load on it and the files have only been small, under 300k, most 50k, and no 2Mb photos like some members will see more want to upload :-)
The a/b/c etc subfolder system sounds like a good option, to keep a max of 9999 ID folders in each subfolder, if I have understood it right.
