Crc32 Software


CRC32 Static Library

CRC32 Static Library for Microsoft VC++ was produced to make your CRC checking operations quick & easy to implement seamlessly without the need for an external DLL The CRC is a "digital fingerprint" of a file, With CRC32 you can "melt down" a huge 20 MB (or even much bigger) file to have a small, handy reference to it, a single 32-bit number like 7d9c42fb (hexadecimal notation) which would unambiguously reflect the entire contents of this huge

Duplicate Finder

Remove true duplicate files, save disk space and run system very smoothly. Duplicate Finder matches byte by byte or CRC32 to give you most accurate result. Faster and more reliable than other duplicate file finders. Providing the user the ability to delete true duplicate files from their system or move it to a separate folder. Free download.

RSP Checksum OCX

This ActiveX OCX can compute very fast the checksum of strings or files using Adler32 , CRC32 , MD5 , SHA-1 and SHA-256 , the code is optimized for new AMD and Intel processors running very fast in the win32 environment


Uses the CRC32 algorithm to identify duplicate files on your system. You can then review the list of duplicates and decide whether or not to delete them. DupeNuker keeps a database of every file it examines, so new files can be checked quickly. New files do not have to be checked against every other file on your system, but only to the CRC32 "fingerprints" in the database, which is very quick.

CRC32 COM Component

The com component will quickly generate a CRC32 checksum in hex or numeric. It also can computer CRC sum of a text string in hex or numeric as the official polynomial used by CRC-32 in PKZip, WinZip and Ethernet.

Command Line SFV Checker

Generate or check the CRC32 of the files list present on the given '.SFV' file. It is very useful in case you must execute a fast CRC32 check of a set of files and you don't have the Windows graphic interface (for example if you administrat e a remote PC using a telnet shell). To obtain software help, you must execute t he command 'Enfis_SFV.exe -h' at Ms-Dos prompt.


DupeWatcher is a profile based powerful duplicate file finder for Windows. It can detect duplicate files irrespective of file names using CRC32 or MD5 content match algorithms. It can also detect duplicate files based on file name, size, create or modified date. It has option to exclude System, Read-only, Hidden files and zero byte files from duplicate search. A powerful filter helps to include or exclude specific file groups or file types.


I created this tool because I wanted to find a way to search my HDD for duplicate file names (designed first for MP3s). I then added the ability to check CRC32 so if the file is name completely different but the CRC is the same then it can detect those also. There are four modes to verify duplication.


ActueFinder is a handy utility that finds duplicate files on your computer. You can then eliminate or move the files to an archive directory, thereby recovering a lot of disk space taken by these unnecessary copies.
