Problem:

The Net Express project file (.APP) is several MBytes large.

Is there a possibility to get it smaller?

Resolution:

The Project file (.APP)  is formatted as an ISAM IDXFORMAT"8"-file.

Therefore, the Net Express ISAM-rebuild command-line can be used:

REBUILD.EXE  INFILE.APP, OUTFILE.APP

to delete unused records from the APP-file within.
