WinRAR è un un'utilità di archiviazione che supporta completamente archivi RAR e ZIP ed è in grado di decomprimere gli archivi CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, 7Z, Z. Crea archivi di dimensioni più ridotte rispetto alla concorrenza, risparmiando spazio su disco e costi di trasmissione.
WinRAR offre un'interfaccia grafica interattiva utilizzabile con mouse e menu così come un'interfaccia da riga di comando. WinRAR è più facile da usare rispetto a molti altri programmi di archiviazione grazie a una speciale procedura guidata integrata che permette l'accesso immediato alle funzioni di base di archiviazione attraverso una semplice procedura di domande e risposte.
WinRAR consente di crittografare gli archivi con AES (Advanced Encryption Standard) con una chiave a 128 bit. Supporta i file e gli archivi fino a 8.589 miliardi di gigabyte di dimensione. Offre inoltre la possibilità di creare archivi autoestraenti e multivolume. Con il record di recupero e i volumi di ripristino è possibile ricostruire anche gli archivi danneggiati fisicamente.
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.
Use "Set master password" button in "Organize passwords" dialog to encrypt saved password records and protect them from unauthorized access.
Prompt proposing to set the master password is displayed when storing a password in compression profile. You can enter the master password to encrypt password data stored in Registry and protect it from unauthorized access. You will need to enter the master password in password prompt dialog to access such compression profile after that.
By default, WinRAR uses AES-256 in CTR mode to encrypt ZIP archives. While AES-256 is significantly more secure than ZIP 2.0 legacy encryption algorithm, it can be incompatible with some older unzip software. If compatibility with such tools is required, you can enable "ZIP legacy encryption" option in the password dialog or use -mezl switch in the command line mode.
Added extraction support for .LZ archives created by Lzip compressor.
Modern TAR tools can store high precision file times, lengthy file names and large file sizes in special PAX extended headers inside of TAR archive. Now WinRAR supports such PAX headers and uses them when extracting TAR archives.
New "Store modification time" option on "Time" page of archiving dialog can be used to prohibit storing the file modification time in RAR 5.x archives. Former "High precision modification time" option is replaced by "High precision time format".
New "Full paths in title bar" option in "Settings/General" dialog. If enabled, the full path of currently opened folder or archive is displayed in WinRAR title bar.
New "Settings/Archives" page provides "File types to open as archives first" group of options. Here you can define how Enter or double click on a file with non-archive extension and archive contents should be processed in WinRAR file list. Examples of such files are .docx or self-extracting .exe archives. You can instruct WinRAR to open such files as archives, to run them, to handle them similarly or differently inside and outside of archives, to never run specified file types even if they do not include any archived contents.
New "Copy full names to clipboard" command in "File" menu places full names of selected files to clipboard.
LZ and ZIPX are added to list of associations in Settings/Integration dialog.
LZ and ZIPX extensions are added to default list of formats for -ms switch ("Specify file types to store") invoked without parameters.
You can specify 'f' charset value in -sc switch to use UTF-8 encoding.
RAR "lt" and "vt" commands display file times with nanosecond precision. Such precision is used in RAR5 archives created by RAR/Unix 5.50 and newer. Archives created by WinRAR have 100ns file time precision.
Only '+', '-' and '1' precision modifiers are supported in -ts switch now. Use '+' to store the file time with maximum precision, '-' to omit the file time and '1' to store it with 1 second precision. Intermediate precision modes previously defined with '2' and '3' modifiers are not available in RAR 5.0 archive format and ignored by -ts switch.
If a wrong password is entered when unpacking an encrypted file in RAR5 archive, WinRAR proposes to enter a valid password for same file again instead of aborting extraction.
File path information is displayed if mouse pointer is placed over a name of archiving file in the operation progress window.
Name of currently active compression profile is displayed in the archiving dialog above "Profiles..." button.
If "Find" command is invoked from inside of archive subfolder, "File names to find" will include the path to this subfolder. So "Find" will search only starting from this subfolder.
WinRAR failed to unpack files in ZIP archives compressed with XZ algorithm and encrypted with AES.
If "Windows progress bars" option in WinRAR settings was turned off and "Put each file to separate archive" archiving mode was used, "gold" part of total progress bar did not display the compressed data ratio correctly.
SFX archive extraction progress was incorrect in case of multivolume SFX archive with total volume size exceeding 4 GB.
If archived folder name included trailing spaces, if user selected and extracted some folders in non-root archive folder and if "Allow potentially incompatible names" extraction option was turned off, WinRAR could lose one or more leading characters in extracted folder name.
If only creation or only last access file time was stored in RAR5 archive with 1 second precision, such as with -ma5 -tsm- -tsa1 switches, this stored time was ignored when extracting.
