X-7Zip is a portable version of the popular 7-Zip, a file archiver featuring a high compression ratio to extract or create compressed files in multiple formats.

It has a straightforward and easy to navigate interface. The main toolbar contains its most used features, and several menus allow you to dig deeper within. For example, the extract button lets you quickly browse for or accept the default destination directory for your file, while the View menu contains a Folder History, and the Favorites menu allows you to save up to ten folders. It also integrates with the Windows Explorer menus, displaying archive files as folders and providing a toolbar with drag-and-drop functions. You can also alternate between a single or dual-pane view.

7-Zip features a high compression ratio in the 7z format with LZMA compression. It supports the packing and unpacking of 7z, XZ, BZIP2, GZIP, TAR, ZIP, and WIM. And it can also unpack 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.
