Hello!!
I actually solve a part of the problem.
Two included project files were suffering with conflicts concering file path - when renaming the two vi's I was able to build an application again, no error about full memory.
I would rather like to fix the conflict than to rename the vi's since the vis are referred to in serveral places, in addition, even if I delete the two project files and include them again from the correct file path, they still are marked with 'conflict'.
When I try to solve the the conflict by picking the file path which I would like to use, I am not able to, because when choosing "save" I get a NEW error : "LabVIEW: Memory is full. Labview save error code 10:default data space"
The strange thing is that I am able to:
1) save single vi after making changes
2) save the whole project
I have read the document you included in the reply and if you have other comments in addition I would be very glad!!!
Best regards,
A
