* Make the task of copying large files between machines easy.
* Split large movie clips into manageable chunks so they can be emailed or ftp to friends.
* Each collection of split parts includes a special rejoin executable that automatically joins all the parts together again.
* Choose whether to Zip files when they are split to make the whole parts even smaller!
* Each ZipAndSplit part is CRC ( cyclic redundancy checked ).

Visual MD5 is a freeware for you to get MD5 checksum of a file. It's a Windows GUI application, which is easy to use and free to distribute!

EF CheckSum Manager is a program designed for the integrity examination of files on the standard formats SFV, MD5 and SHA1. They can verify existing checksums or create new checksum for your important data. The EF CheckSum Manager is easy to use and much fast, supports the recursive processing of file structures, works up to whole drives.

Docklight Scripting is an extended edition of Docklight RS232 Terminal / RS232 Monitor. It features an easy-to-use script language, plus a built-in editor to create and run automated test jobs. A Docklight script allows you to execute all basic Docklight functions (sending predefined data sequences, detecting specific sequences within the incoming data stream, ...) and embed them in your own test code.

CRC32 COM Component is for ASP, .NET, Cold Fusion, VB, VC++ and other languages.

The com component will quickly generate a CRC32 checksum from files or a text string in hex or numeric as the official polynomial used by CRC-32 in PKZip, WinZip and Ethernet.

CRC .NET control is the checksum library for .NET developers.The library, especially written on .NET framework, provides exact and fast calculations of checksums. The library has an easy to use interface, fast and reliable infrastructure and provides calculation of CRC32, CRC16 and CRC8 polynomial checksums, like used in the Ethernet, WinZip and so on. Also, custom polynoms are supported.

AnyReader: Effectively copy corrupt data from any type of disks or faulty connections when standard copy methods fail. AnyReader supports resumed downloads from a remote PC if the connection was broken during the copy process (especially useful for Wi-Fi).

Comprehensive SFV and MD5 checksum utility for Windows. The handy and fast utility for protecting the integrity of files. It will allow you to verify the accuracy of your data after you burn a CD or transfer a files over a network. Adding an little checksum file to your data files will allow in further easily to verify their integrity at any time. Uses checksum files fully compatible with popular md5sum utility for MD5 and SFV for CRC32.

Utility for protecting the integrity and verifying the accuracy of data files using checksum (message digest, hash) calculation algorithms like CRC32, MD5, SHA-1 and more. Its will allow to easily and quickly verify integrity of files downloaded from Internet, transferred over a network and/or burned onto CD/DVD. Uses the XML-based and Unicode-enabled checksum file format and also supports the SFV, MD5SUM and other checksum files formats.

[ASP] A program that allows backup and restore of files that span multiple floppy disks. It is not dependent upon the version of the DOS or Windows(tm) operating system. The floppy disks can already contain other files. The language of prompts and messages can be changed. The backup/restore process uses cyclic redundancy checks (CRC) to assure exact file integrity.

Directory printer, Print a directory tree of an entire disk or a single directory. Prints DLL,EXE version info. Prints to a printer,Text,Clipboard,Excel,Excel program,XML or HTML file. Prints AVI,MP3,MSI,WAV info. Prints cyclic redundancy checksum CRC. Find duplicate files. Find duplicate directories. Multiple file rename. Multiple file change date. Multiple file change owner. Shows file owner. Reports total file size by the file owner
