If the associated application is present on your system, you should reinstall it, in order to restore the file type. When an extension or file type is red-flagged because the associated program is missing, the problem may be that you moved the program to a new location. In that case, you can reinstall the program or use PC Magazine 's utility COA32 to notify the system of the application's new location. If, however, you've removed the application from your system, you should delete the file type. Select it, click the Advanced page, and click the Remove type button.
Freedom backs up the file type's data and then deletes it.
Some extensions are registered with the system but have no associated file type. In some cases, such an entry serves to define a browser-style content type for the extension. In other cases, a particular application may be storing program-specific information with the extension. If the extension has no associated data at all, however, it's just wasting space in your registry and Freedom flags it with a yellow icon. An extension that has no associated information except a spurious New menu item will also be flagged.
