FEADIE (File Extension Association for Download in IE)
There is Opera which can download any file from web and maybe other tools & regedit that can edit file association but I havent found anything fast, easy, and free to do that. Hope it helps someone.
FEADIE helps when Internet Explorer keeps telling "Error: This file cannot be viewed on the device". Setting this file extension in FEADIE should solve this error message.
In case you want to download some file and it is displayed as text, go to "\Windows\Profiles\guest\Temporary Internet Files\Content.IE5" and find the file by its filename. (This problem often relates CAB files because many web servers are missing Content-Type for this extension.)
