ComparatorPro will finds, deletes and copies over duplicate files, it will also find missing files and perform full backup routines. It will shows you a side by side list of the contents of any two files so you can see what is missing and what is new. It can easily sync the files to ensure a perfect match. And here, too, is an alternative to the Microsoft Briefcase, install ComparatorPro everywhere you go to keep shared files in sync.

Advanced Zip Repair (AZR) is a powerful tool to repair corrupted Zip and self-extracting(SFX) files. It can scan the Zip archives and recover your data in them as much as possible, so to minimize the loss in file corruption. Currently AZR can fix all sub-types of Zip files and all kinds of self-extracting files, also it will provide a tiny exe stub when repairing SFX files.

TeraCopy is a free utility designed to copy/move files faster and more secure. Can resume broken file transfers. TeraCopy skips bad files during copy and even shows the skipped files at the end of files transfer. Calculates files CRC checksum on the fly to speed up source and target files comparsion. Seamless integration with Windows Explorer allows you to keep working with files as usual.

SecurityPlus is a powerful encryption and decryption utility with a file viewer, thumbnails, slideshow and program selector, runs in the tray and offers full privacy of images, other files, and applications using on the fly encryption, decryption. SecurityPlus is very fast and will not take long to encrypt, decrypt even large files including files on CD-ROM. Current passwords (keys) can be quickly cleared and files can be safely deleted (shredded

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.

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.

zsCompare lets you manually or automatically compare and synchronize Windows or Mac OS X files, folders, and zip files between local directories or networked computers. You can also compare the contents of text files line by line, and then merge the files to include only the changes you want. Freeform text comparison lets you compare text from any source including Word and PDFs. Finally, zsCompare includes a powerful duplicate file finder.

Fast file checksum generation & verification tool. Allows to create/verify popular file hash/checksum: MD2,MD4,MD5, SHA-1,SHA-2(256,384,512), RIPEMD-160,PANAMA,TIGER, CRC-32,ADLER32, and the message digest used in eMule/eDonkey(ed2k) software. Use it to check files for corruption (data integrity checking). Allows to recurse directories. Supports MD5 & SFV files. Compatible with md5sum, MD5Summer, Easy MD5 Creator, SFV Checker/Verifier, Win CRC32.

Directory printer, Print a directory tree of an entire disk or a single directory. Prints DLL,EXE version info. Prints to a printer, Text, Excel, 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

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.

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

Fast, highly optimized implementation of hash and checksum algorithms: MD2, MD4, MD5, SHA-1, SHA-2(256,384,512), RIPEMD(128,160,256,320), PANAMA, TIGER, CRC-32, CRC-16, CRC-CCITT, ADLER32. The library allows to calculate hashes (message digests), checksums and HMACs for files, memory blocks, strings, streaming data. Has no external dependencies such as MFC DLL, COM/DCOM or other component. The help file has examples in Visual Basic(VB), C, C++.

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.

Fast, highly optimized implementation of popular checksum algorithms: CRC32, CRC16, CRC16C (CRC-CCITT). The library allows to calculate checksums for files, memory blocks, strings, streaming data.

This is a programmable multiple-precision hex calculator with many utilities. With Hpmbcalc, you can easily perform a lot of big number math and encryption operations, such as: square root, modular inverse; hash, CRC, and check sum make; shift register configuration evaluation and simulationl; pseudo-random number generation; primality test; hex, dec, oct, bin conversion; etc.

CDCheck is utility for prevention, detection and recovery of damaged files with emphasis on error detection. It offers readability verification, creation and checking of MD5, CRC-32, SHA... hashes (in file formats SFV, MD5 and CRC), extremly efficient file compare and recovery. CDCheck can be used on all files visible by the operating system. Apart from this it also works with audio CDs and provides information about inserted CD/DVD (type...).

This Assembly Language program is for splitting large files for easier distribution. Using either a normal window or a wizard interface, files can be split by either the number of files that you want, the maximum file size, or you can use preset common sizes for EMailing, floppies, Zips, CDs, etc... The program supports file time and attributes preserving, CRC, BAT file unchopping, command line operation and even simple encryption.

SFV Checker uses CRC-32 technology to check each file and notifies you of any potentially bad, corrupt, incorrect size or missing files to save you hours of downloading only to find you have 1 file missing or the last file has a CRC checksum error.
