Open the b4a file with a text editor and check its content.

I open the b4a file using notepad and tried rename the files to .txt but unfortunately both File.b4a and File.b4a.meta show empty spaces.

My layout files are not corrupted. I lost Main activity module and a Login activity module.
It's alright, may be I just need 1-2 hour to build them back. I should have made a backup.
