Version 5.50 beta 3
1. Added support for Unix extended timestamp extra field
(0x5455 extra field tag) in ZIP archives. Such timestamps are used
by InfoZip to store UTC file time additionally to standard
ZIP local time. Now WinRAR reads and sets such timestamps
2. "Run", "Open in associated application", "Show archive contents"
items are added to right click menu in WinRAR file list.
So you can right click SFX archive or archive file with non-archive
extension like .docx and choose if you wish to browse its contents,
to run or open it.
These items are present only in the file management mode
and are not available inside of archives.
3. "File types to open as archives first" option is moved from
"Settings/Archives" to "Settings/Compression". Now it works only
outside of archives to avoid conflicts with "Settings/Viewer/
Unpack everything for" option.
Default folders for archives and extracted files are moved
from "Settings/Compression" to "Settings/Paths" dialog page.
4. Bugs fixed:
a) some files in TAR archives could be unpacked with full paths
even if "Extract relative paths" option was enabled.
