It’s very hard to access hidden folders, such as the .obsidian folder on an iOS or iPadOS device, so far i have only found one paid third party app that’s able to do it.
Proposed solution
Expose the .obsidian folder in some way.
Either by making it possible to unhide it or preferably by being able to open and edit files, such as snippets, inside .obsidian through Obsidian itself.
Current workaround
Use a computer or paid third party app to access and edit the files in .obsidian
Even long-standing FR with 140+ comments like this one list as a workaround copying around the hidden config folder - which faceplants into this problem on mobile.
Surprisingly, this issue runs deep: even plugins that deal with “hidden” folders are consistently listed as unsupported on mobile, which sounds like even the Obsidian APIs are neutered on purpose. Example: GitHub - codeonquer/obsidian-sync-config-folder-to-common-folder
At some point I feared that maybe it’s the mobile OS itself that stops Obsidian from touching hidden folders; but that’s not it, because people successfully use various 3rd-party apps to deal with Obsidian’s own folders. E.g., Taio, iSH, a-Shell.
Since you linked to my old thread (2023), I will give a small update and say I really think you are on to something. At no point did I realize you could only sync a single configuration folder until you revived this 2021 thread in 2025. I eventually gave up on Obsidian Sync mainly because of the configuration sync issues and starting using Syncthing to sync between my phone and desktop, and it became instantly obvious how to sync and use both the .obsidian and .obsidian-mobile folders and it just worked, with no ambiguity as how to move plugin settings from one side to the other. Then I thought, well I guess I could have done that with Obsidian Sync too, why didn’t I think of that then? Then I saw this thread which and realized it still wouldn’t have worked to have the two folders. No one in my thread pointed that out to me either. I should have emailed support at some point, but for whatever reason I didn’t.
