The .xar extension file is created by versions of Microsoft Excel launched in 2007 and all versions launched after that. This is done when the computer crashes or shuts down unexpectedly following a power failure or due to any unforeseen sequence of events. A .xar extension file is an auto-saved version of the file that the user is working on. It helps the user to recover the work done without it being lost. Thus it saves time and effort in having to do the work all over again. Other associations of the .xar extension file format include files created using the Xara Xtreme Drawing Application developed MAGIX and the Extensible Archive Format Files used on UNIX Platforms as well as by Mac Operating System for routine software installation and browser extensions.
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.

Excel automatically saves the file that is being worked by the user at every 10 minute intervals in a .xar extension format. The .xar extension file would be randomly named so it would be best to sort the files in the folder with the Date Modified option and look out for the latest .xar extension file on the list. The Extensible Archive Format that uses a .xar extension is basically used on UNIX platform. It contains either a single or multiple files with or without compression. It consists of a header index based on XML technology that enables an easy search of the contents of the archive.
The RAR archive format supports compression, file spanning, and error recovery. Compression is carried out using a prediction by partial matching algorithm and the lossless compression algorithm LZSS. The RAR file format has a range in file size from as low as 20 bytes to 8 exbibytes less 1. It also supports AES encryption at 256bits as well as the CRC32 checksum and BLAKE2 file hash algortihms.
