7-Zip.org - 1.1 MB ( Open Source)
7-Zip allows for free to compress, decompress and encrypt any file or folder having a high compression ratio.
7-Zip is an archiving tool such as WinZip or IZArc , that can be choose to use because it is free.
The application can compress your files and folders so that they use less space on the hard disk. It is particularly able to compress a file with a high compression ratio, in order to obtain smaller files, easier to store or send. Its handling is very simple and does not require significant hardware resources.
The program is able to create archives in 7z format, TAR, gzip, bzip2 and zip. It supports reading formats like ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, HFS, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, squashfs, UDF, VHD, WIM, XAR and Z but for archive creation, it is limited to 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM.
7-Zip also allows to encrypt the documents, but also can create archives that can be unpacked without using the software.
It allows to create self-extracting files for easy retrieval for users who are sending the files.
The software have an encryption option too, requesting a password to encrypt a file. Only Zip and 7z formats support encryption. The encryption algorithm used is based on AES-256 to a certain robustness attempts to brute force attack encryption.
The speed for single-thread LZMA/LZMA2 decoding was increased by 30% in x64 version and by 3% in x86 version.
7-Zip now can use multi-threading for 7z/LZMA2 decoding, if there are multiple independent data chunks in LZMA2 stream.
7-Zip now can use multi-threading for xz decoding, if there are multiple blocks in xz stream.
The speed for LZMA/LZMA2 compressing was increased by 8% for fastest/fast compression levels and by 3% for normal/maximum compression levels.
7-Zip now shows Properties (Info) window and CRC/SHA results window as "list view" window instead of "message box" window.
Some improvements in zip, hfs and dmg code.
Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode in Windows 10 because of some BUG with "Large Pages" in Windows 10. Now 7-Zip doesn't use "Large Pages" on Windows 10 up to revision 1709 (16299).
The vulnerability in RAR unpacking code was fixed.
Some bugs were fixed.
