Iside compares files and folders by computing their hash code (MD5,SHA1,...). Right click on a file, select Copy and by right clicking on another file you will discover if they are equal. Includes file comparison, hash displaying tool plus a complete folder comparison tool. The hash functions allow to determine if two files are different even if their size is the same. Ideal tool for configuration managers, programmers, deployers.
Zlib is a free general-purpose data-compression library. Integrity checks performed with the CRC-32 or the ADLER 32 checksums. In-memory operations use the zlib compressed data format (RFC 1950). Deflate (RFC 1951) is used for its compression algorithm. Typical compression ratios are between 2:1 and 5:1. The gzip format, RFC 1952, is supported for compressing files on a file system. Lacks support for PKZip 4.5, BZip2, and Deflate64.
