Backup Copies

GF_ProjectVX code includes a backup feature of the previous version of the project on which you are working.When you explicitly save the project, GF_ProjectVX code saves the current version (before save) of the project in the PreviousVersions folder stored at the same location of the project folder; You can set the upper limit of the backup files to be kept on your PC. By default this is 10, set to 0 if you want to disable this feature (see Paragraph 3.6 for more details).If GF_ProjectVX code is not able to open a project, if it gets corrupted for example, an error mes- sage is shown telling the user that the project cannot be anymore opened and asking if GF_ProjectVX code should open the last saved previous version.
