An archiver is a program for packing one or more files into a single archive file for easy transfer and storage of data.
Windows 10 has built-in functionality for archiving files, but it does not support some types of archives and generally has few features. Therefore, the need for a third-party archiver in Windows is and always has been.
Among the archivers, one can single out the 7-Zip program, which is very functional, convenient and free.
