Enterprise Developer is pre-configured to associate certain file extensions as specific COBOL file types. For example, the following extensions
               are recognized as COBOL programs - 
               		.cbl, 
               		.cob, 
               		.eco, 
               		.pco or 
               		.sqb; 
               		.cpy and 
               		.cbl are recognized as copybooks. 
               	 
            
 
            	 
            To add file associations for other file extensions: 
               	 
            
 
            	 
             
               		
               - In the IDE, click 
                  		  Window > Preferences. 
                  		
               
- Choose 
                  		  General > Content Types. 
                  		
               
- In the 
                  		  Content type pane, expand 
                  		  Text and click 
                  		  Micro Focus Project Types. 
                  		
               
- Click on any of the types prefixed 
                  		  COBOL in the list to see which file extensions are associated with that particular type. 
                  		
               
- To associate a new extension with any particular type, click 
                  		  Add, and then specify the 
                  		  Content type.
