Hi @JFrench ,
Do you want to retrieve data based on the file storage structure of the library(Just like in SharePoint)?
Do you want to auto-populate the textinput control based on the user's selection in Gallery?
If so,please try this solution:
1\My library is picc
2\Add a Gallery and set it's items property to
If(CountRows(TheLog)=0,Filter(picc,CountRows(Split('Folder path',"/"))=2),Filter(picc,'Folder path'=Last(TheLog).Value)) /*TheLog is my custom collection*/
3\Set the left arrow's OnSelelct property to:
If(ThisItem.IsFolder,Collect(TheLog,ThisItem.'Folder path'&ThisItem.'File name with extension'&"/"))

4\Add a button and set it's OnSelelct property to
Clear(TheLog)
Text
"Return to the root directory"

5\Set the textinput control's Default property to
GalleryName.Selected.'Link to item'
Best Regards,
Bof
