MB-Medium (2).rar

RAR is a proprietary archive file format that supports data compression, error correction and file spanning.[3] It was developed in 1993 by Russian software engineer Eugene Roshal and the software is licensed by win.rar GmbH.[3] The name RAR stands for Roshal Archive.

The filename extensions used by RAR are .rar for the data volume set and .rev for the recovery volume set. Previous versions of RAR split large archives into several smaller files, creating a "multi-volume archive". Numbers were used in the file extensions of the smaller files to keep them in the proper sequence. The first file used the extension .rar, then .r00 for the second, and then .r01, .r02, etc.

The media type for rar files, registered at IANA in 2016, is application/vnd.rar (see -types/application/vnd.rar). The mime-type value, application/x-rar-compressed, was used before that and is still commonly used even though it is marked as deprecated in the document above.

While the former matching is correct, for the latter IANA reports here -types/application/vnd.rar that for rar application/x-rar-compressed is a deprecated alias name and instead application/vnd.rar is the official one.So, right Media Types from IANA in 2020 are:

.rar (self-extracting archive files created with the WinRAR archiver), .jar (Java archive files), and .obj (compiled source code, 3D object, or sequence files) files are not considered to be executable file types. To block these files, you can use mail flow rules that look for files with these extensions as described earlier in this article, or you can configure an antimalware policy that blocks these file types (the common attachment types filter).
