WinRAR is a powerful archive manager. It can backup your data and reduce the size of email attachments, decompress RAR, ZIP and other files downloaded from Internet and create new archives in RAR and ZIP file format.
WinRAR - What's new in the latest version
Version 4.10 beta 4
1. Improved detection of UTF-8 encoding in file names in ZIP archives.
WinRAR attempts to recognize Unicode names, even when UTF-8 flag
is not present in ZIP archive headers.
2. Bugs fixed:
a) If switch -t was set in RAR environment variable, WinRAR "View"
command failed to open archived files;
b) ""Autodetect" string" option in "Define volume sizes" dialog
did not work;
c) If "Split to volumes, size" in default compression profile was
set to "Autodetect", "Delete" and "Add comment" commands refused
to modify ZIP archives.
