WinRAR 4.01 Free Download

A very powerful archiver and archive manager for home or office use

The WinRAR application was developed to be a powerful compression tool with many integrated additional functions to help you organize your compressed archives.

WinRAR puts you ahead of the crowd when it comes to compression. By consistently creating smaller archives, WinRAR is often faster than the competition. This will save you disc space, transmission costs AND valuable working time as well.

WinRAR supports all popular compression formats (RAR, ZIP, CAB, ARJ, LZH, ACE, TAR, GZip, UUE, ISO, BZIP2, Z and 7-Zip).

WinRAR is ideal for multimedia files. WinRAR automatically recognizes and selects the best compression method. The special compression algorithm compresses multimedia files, executables and object libraries particularly well.

WinRAR allows you to split archives into separate volumes easily, making it possible to save them on several disks for example.

WinRAR is also ideal, if you are sending data through the web. Its 128 bit password encryption and its authenticated signature technology will give you the peace of mind you have been looking for.
Here are some key features of "WinRAR":

· WinRAR introduces an original compression algorithm. It provides high compression ratios on executable files, object libraries, large text files, etc.

· WinRAR offers an optional compression algorithm highly optimized for multimedia data.

· WinRAR supports files and archives up to 9,223,372,036,854,775,807 bytes in size, about 9000PB. The number of archived files is unlimited for all practical purposes.

· WinRAR provides complete support for RAR and ZIP 2.0 archives and is able to unpack CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, Z, 7Z archives.

· WinRAR supports NTFS file security and data streams.

· WinRAR offers both a classic interactive Windows interface and the command line interface.

· WinRAR provides functionality for creating a 'solid' archive, which can raise the compression ratio by 10% - 50% over more common methods, particularly when packing large numbers of small files.

· WinRAR offers the ability to create and change SFX archives using default and external SFX modules.

· WinRAR offers the ability to create a multi-volume archive as SFX.

· WinRAR offers a number of service functions, such as setting a password, adding archive and file comments. Even physically damaged archives may be repaired and an archive may be locked to prevent further changes.

· The number of files, which can be added to an archive, depends upon the amount of available memory and the length of file names. Roughly 128 bytes of memory are required per archived file for RAR archive. For example, it can take about 128 MB to compress one million of files. WinRAR has been tested to handle over one million of files.
· The size of a RAR archive, as well as the size of any single file within a RAR archive, is limited to 8,589,934,591 GB (9,223,372,036,854,775,807 bytes). Note that to create archives larger than 4 GB, you need to use NTFS, as older file systems do not support such large files.
· The size of a ZIP archive, as well as the size of any single file within a ZIP archive, is limited to 2 GB.
· In general RAR archive format is much better optimized for heavy tasks involving huge number of files and gigabytes of disk space.
· 40 days trial
What's New in This Release: [ read full changelog ]

· Added support for file sizes stored in binary format in TAR archives. Some TAR archives use the binary size format instead of octal for files larger than 8 GB.

Bugs fixed:
· "Repair" command failed to properly reconstruct structure of RAR archives, which contained at least one file with packed size exceeding 4 GB. This bug did not affect the recovery record based repair. It happened only if recovery record was not found and WinRAR performed reconstruction of archive structure;
· even if "Do not extract paths" option in "Advanced" part of
· extraction dialog was set as the default, WinRAR still unpacked
· file paths if called from Explorer context menu;
· after entering a wrong password for encrypted ZIP archive, sometimes WinRAR ignored subsequent attempts to enter a valid password;
· "Wizard" command did not allow to create self-extracting and multivolume archives, when compressing a single folder or a file without extension;
· "Import settings from file" command did not restore multili...
