There is a difference between B4A and B4J with File.ListFiles(File.DirAssets). This code works in B4A but not in B4J: For Each FileName As String In File.ListFiles(File.DirAssets) This code works in B4J but not in B4A: For Each FileName As String In File.ListFiles("../files/") For cross-platform p

I'm using the DirAssets folder to store text files which are used in my App. If I look in the files explorer there are 21 of these files. If I look in the files tab of the B4A IDE there are also 21 files. I have synchronised the Files tab, and used clean files and clean project. 'Get files

link: As I understand it File.ListFiles should work in File.DirAssets but File.Exists doesn't. Witness the Intellisense in the IDE.

The folder probably doesn't exist. File.ListFiles returns an uninitialized list if the folder is not accessible. Dim lstFile As List=File.ListFiles(File.Combine(File.DirInternal, "Pldata")) Log(lstFile) If lstFile.IsInitialized Then lstFile.Sort(True) End If

link: then use file.Listfiles That´s the command in B4X to list files from a folder.

link: Is there a way to use File.ListFiles to read a directory sorted by file size or would I have to read the directory and look up and then sort by size?
link: Yep. That's pretty much (almost line per line) of what I came up with. I was just wondering if there was a way built into Android or B4x. Thanks.

It will not work. See File.ListFiles documentation: https://www.b4x./?query=file.listfiles It returns a read-only list. If you need to modify it: Dim list1 As list1 list1.Initialize list1.AddAll(File.ListFiles(...))

File.ListFiles returns an array. You are adding the complete array as a single element. Dim lifi As List = File.ListFiles(...) 'or if you want to have a modifiable list (which I'm pretty sure isn't the case here): Dim lifi As List lifi.Initialize lifi.AddAll(File.ListFiles(...))

My app compiled with B4A 12.80, and running on a Samsung Tablet with Android 13, is supposed to list folders and files in a selected folder, but is only showing the folders.
