But file is for sure here... It looks like some old IDE bug, it was many times before with other projects.
Maybe related to the fact that B4XPages project was ZIPped by "Export As ZIP" menu and edited next separately ?

SOLVED: the path was ""C:\!\bigfile\B4J\bigfile.b4j".

"!" is forbidden, as i remember, removing helped.
