While developing my open-source project Journaley, I ran into a situation where I wanted to detect a specific folder inside the App Folder of Dropbox root directory. This was not a trivial task, because the App Folder name differs depending on the Dropbox user's language setting. So, I manually switched between different language settings and checked the name of the App Folder created by Dropbox in each language. The table below is the summary of what I found, which I keep here for future reference.
