Convert ar to txz

What is the difference between .ar and .txz?

Description: AR is a Unix archive file that is purposely used to develop and update static library files for creating .deb packages. Currently, its been replaced by .tar archive file for everything except static libraries.; The TXZ file format is a combination of TAR archiving and XZ compression. It is used to pack multiple files into a single archive (TAR) and then compress it using XZ compression to reduce the file size. The TAR aspect allows for the collection of various files and directories into a single file, preserving their structure and attributes. The XZ compression, known for its high compression ratio, further compresses this archive, making the resulting TXZ file more efficient for storage or transmission.
