tlzma The .tlzma extension is an indication that file is archived as well as compressed. Generally, these are data files that have been archived by the TAR Archiver using the LZMA algorithm for compression. These files are smaller in size and can be decompressed faster in comparison to the other popularly used compression formats like GZIP and BZIP.
rar The .rar filename extension is a popular and partially open archive file format associated with the compression and decompression tool WinRAR. The format was developed by Eugene Roshal with its initial release in 1993. It, like many other archive formats, acts as the compressed data container for one or several files. The archive format can maintain the directory structure of the compressed archive even when unpacked to a directory. The RAR file format supports multi volume file compression where an archive is saved as a sequence of several files of a given size.
