The file cannot be opened because it is currently in use by another application

Users may get the following warning when trying to open a file:

File ‘C:\CYPE Ingenieros\Projects\program\file.extension’ cannot be opened because it is currently in use by another application.

The file may already have been opened by another session of the same application you are running at that time. When in doubt, close all sessions of all CYPE programs, re-run only one session of the program you need to work with and try to open the file again.
