B4J Question Latest file in folder

[TomDuncan]

Hi I have a program which generates images every 30 seconds.
What I need is a way to find in that folder the latest image.

Look for jFilewatcher!

If it's your program that is creating the files, the most efficient way would be to store the last filename.

Otherwise you could use File.ListFiles to get all the files in the directory, then check the last modified date of each file.

Or this library https://www.b4x.com/android/forum/threads/jfilewatcher-watch-system-file-events.56613/
