You can create folders on the drive to organize your images. However, if you upload an image with a name that is already used by another image on the drive, D360 automatically adds an index number in parenthesis to the name of the newly uploaded image, even if the other image is in another folder!

Example:

Images

+- Folder A

+- Image.png (file that is already there)

\- Folder B

+- Image(1).png (new image uploaded with Image.png is renamed!)

This is ridiculous and makes the folder hierarchy pointless. Especially, as you can freely move images around the folders, because the images are distinguished by a UUID and on the filename.
