The .rel format is associated with the Nintendo Wii, a video game console first released in 2006. Nintendo Wii software uses these files as relocatable modules.
A REL file can contain executable code and related data loaded by a Wii program at runtime. Its role is similar to that of a DLL (dynamic-link library) in Microsoft Windows, although it is a different format for a different platform.
REL files are intended for Wii software rather than general-purpose desktop use. The format remains tied to software developed for the Nintendo Wii.
A .rel file is normally used as part of a game or another program for the Nintendo Wii and is not meant to be opened directly by users.
A Wii REL module cannot normally be converted to a document, image, or another general-purpose file format. It is a compiled program module rather than an interchange file.
There is no ordinary conversion process for an existing REL file.
