I have created a gallery that shows a Document Library, the first thing that shows up is the all the Folders that have been created. I can select the folder and see all the files. My issue is how to navigate back to that first view with all the folders show. Also, I would like for the gallery to reset to that first view when the file is saved or closed.

I have tried Navigation(gallery4) and it did not work, and the Back() function but it just took me the first screen of the app.

Hi @lbolin ,

Can you please share how the process works in your app where user select a folder and then the files are shown? Do you use a collection for this? Any screenshots would be most helpful.

@BCBuizer
Ok so I found this tutorial (Power Apps Navigating Folders & Subfolders In A SharePoint Document Library (matthewdevaney.com) and I have the basic functionality, but my gallery is too small. Is there a way to replicate this on a back button icon I have on there or something like that.
Before i select the folder name
After I select the file name. I select the Car Files and it goes back the folder View.

I am just wanting if you select the back button to go back in the directory.

Hi @lbolin ,

The below formula should do the trick:

Set( varFolderPathCurrent, Concat( With( {_FilePath: Split(varFolderPathCurrent, "/").Value}, FirstN( _FilePath, CountRows(_FilePath)-1 ) ), Value, "/" ) )

The way this works is that is takes the current path from the variable, splits it, removes the last part and then concatenates the result back to a string which is saved to the variable.
