WinRAR 7.20 Beta accelerates solid archive deletion and large ZIP handling

WinRAR 7.20 Beta introduces major performance improvements when deleting files in solid RAR archives, reducing recompression and copying unaffected blocks directly. The update also refines SFX variables, path exclusion, and fixes issues with ZIP archiving and password handling during archive conversion. Advanced options for generating archive names by weekday or month, and revised command-line switches for solid archives, have been added.
