Opening a COBOL 
                     			 or a PL/I 
                        			 project in 
                     			 Enterprise Developer modifies the 
                     			 .cobolProj 
                     			 and 
                        				.pliProj 
                        			 files. Once modified the 
                     			 .cobolProj 
                     			 and 
                        				.pliProj 
                        			 files 
                     			 are no longer backward compatible with older versions of 
                     			 Enterprise Developer. This prevents you from opening the same projects in earlier versions of 
                     			 Enterprise Developer. 
                     			 
                     Note: Micro Focus recommend that you backup your 
                        				.cobolProj 
                        				and 
                           				  .pliProj 
                           				 
                        				files before opening projects created in earlier versions of 
                        				Enterprise Developer.
