Let's clarify something here: how exactly did you create the "documents" gallery folder you're referring to? If you created this folder using the Gallery app, then that's what I was referring to in my previous post--folders created within the Gallery app may not necessarily be physical directories on your internal storage or SD card. They're organizational constructs that are used only within the Gallery app. I think (but am not 100% sure) that the Samsung Gallery apps do this kind of thing.
However, if you created a physical directory called "documents" on the SD card using a file manager app, that's a different case.
How are you accessing the forum on your phone? Using the desktop or mobile web page on a browser, or the Android Central app, or the Android Central Forums (from Tapatalk) app?
Thanks for the clarification questions. Hopefully my answers will help me resolve this issue.
I created a "documents" folder (lower case "d") via the file manager on my phone. I used lower case "d" because the Gallery app comes with a default "Documents" folder with upper case "d". I transferred everything over and don't have a problem seeing the new "documents" folder and its contents in the gallery, with an SD Card icon (telling me that it is indeed stored on my SD Card. I have no issues with opening that folder and viewing the contents either (which tells me that the files are indeed there and viewable).
I plug my phone into the computer, open up the appropriate directory, can see all my other folders on either the internal storage and SD Card, but the one exception is the newly created "documents" (the new lower case d one).
I do not access the forum on my phone. It will open, I can read the first page and then it jams and I have to clear all my tabs, restart my phone and open up any tabs I closed (on both the default Samsung browser or Chrome). But that's an entirely different issue. I am using the forum now on my PC.
Hopefully that info helps answer your questions.
Thanks in advance B. Diddy.
