The system cannot find the file specified.

Fix - Go to the top of B4XMainPage and delete this line:

#CustomBuildAction: folders ready, %WINDIR%\System32\Robocopy.exe,"..\..\Shared Files" "..\Files"

Why it happens?

It happens with B4XPages projects, when the developer uses File - Export as zip to create the zip file instead of clicking on:

'Ctrl + click to export as zip: ide://run?File=%B4X%\Zipper.jar&Args=Project.zip

The Zipper tool is more sophisticated and it preserves the B4XPages project structure.
