Notes about the XEN 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 XEN file type is primarily associated with 'Xenu's Link Sleuth' by Tilman Hausherr. Xenu's Link Sleuth checks Web sites for broken links. Link verification is done on normal links, images, frames, plug-ins, backgrounds, local image maps, style sheets, scripts and java applets. It displays a continuously updated list of URLs which you can sort by different criteria. A report can be produced at any time.
