IZarc is a proprietary file archiver developed by programmer Ivan Zahariev for Microsoft Windows. It is closed source freeware for file compression with a portable version on the application’s web site. The common compression and archive formats utilized by this application are zip, gzip, tar.gz, bzip2, 7z,iso, jar, rar, and other files with less common formats. A distinguishing feature of IZarc compared with similar tools is its ability to convert archive formats into different formats, and conversion between standard and self-extracting archives. It can be integrated seamlessly with Windows Explorer, which means the application can be used without opening its interface. IZarc can convert CD images, perform disk spanning from and to multiple diskettes or other removable media, merge or create multi-volume sets, create self-extracting archives, and repair broken archives. It also performs reconversion of self-extracting .EXE files to standard archives (UnSFX). It contains a virus scan feature to protect files and uses Rijndael - AES (256-bits) encryption for the encryption of files.
