Opening a COBOL 
                  		  project in 
                  		  Visual COBOL modifies the 
                  		  .cobolProj 
                  		  file. Once modified the 
                  		  .cobolProj 
                  		  file 
                  		   is no longer backward compatible with older versions of 
                  		  Visual COBOL. This prevents you from opening the same projects in earlier versions of 
                  		  Visual COBOL. 
                  		  
                  Note: Micro Focus recommend that you backup your 
                     			 .cobolProj 
                     			  
                     			 file before opening projects created in earlier versions of 
                     			 Visual COBOL.
