I'm returning to iOS after several years of Windows, and hoping to find a file manager for iPad Mini that can do this: Let me rename a jpg / jpeg file in Dropbox Let me create a duplicate copy of the image file in Dropbox with a new name Let me open the file with a photo editor app (of my choice) I tried TapMedia's File Manager app, but it inexplicably converts jpeg files to png format without warning. I need to retain the jpg/jpeg file format. Dropbox app itself has some file management abilities, but it does not seem able to let you rename or make a second copy (with new name) of a file. Any suggestions? Thank you.
