WinRAR – What’s new in the latest version
1. WinRAR and command line RAR use RAR 5.0 archive format by default.
You can change it to RAR 4.x compatible format with “RAR4” option
in archiving dialog or -ma4 command line switch.
If you prefer RAR 4.x format by default, use “Create default…”
button on “Compression” page of WinRAR settings and set “RAR4”
in the displayed dialog.
This change affects only new clean installs. If you already saved
RAR format in the default compression profile in previous versions,
WinRAR respects stored settings.
2. Use “Set master password” button in “Organize passwords” dialog
to encrypt saved password records and protect them from unauthorized
If saved passwords are protected with master password, you need to
enter the master password and press “OK” in password prompt to access
them. If entered password does not match the master password,
it is treated as a usual password for archive operations.
Once entered, the master password is valid until WinRAR is closed.
Close WinRAR and open it again after specifying the master password
if you wish to see how protection works. Enter a valid and then
empty master password to remove encryption from previously protected
This WinRAR version uses a new data format for password organizer,
so passwords stored in “Organize passwords” dialog are not readable
by older versions. It does not affect archive encryption formats
and encrypted archives are compatible with previous WinRAR version.
Organizer data is converted to a new format only when you save it
and not immediately after installing WinRAR.
