Notes about the EDX file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The EDX file type is primarily associated with 'Editor' by Serenity Software. Editor copyedits and proofreads writers' texts at the level of words and phrases. EDX files are private, encrypted database files for use by the Editor application. Serenity Software has been publishing software since 1990.
