Convert taz to xpi

What is the difference between .taz and .xpi?

Description: A TAZ file is essentially a compressed archive created using the Unix-based Tar archiving utility, with compression applied through the compress program. The "tar" part of the filename stands for "tape archive," reflecting the utility's origins in backing up data to tape drives, while the "z" indicates that the archive has been compressed using the Lempel-Ziv (LZ) algorithm to reduce its size.; Efficient XML Interchange (EXI) is a binary XML format for exchange of data on a computer network. It was developed by the W3C's Efficient Extensible Interchange Working Group and is one of the most prominent efforts to encode XML documents in a binary data format, rather than plain text. Using EXI format reduces the verbosity of XML documents as well as the cost of parsing. Improvements in the performance of writing (generating) content depends on the speed of the medium being written to, the methods and quality of actual implementations.
