Advanced CheckSum Verifier

Comprehensive SFV and MD5 checksum utility for Windows 95/98/Me/NT/2000/XP/2003. The handy and fast utility for protecting the integrity of files by using the CRC32 or MD5 checksum calculation algorithms. 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. This program is especially effective if you have many files, many subdirectories, or both. And it's extremely fast and lightweight. Uses checksum files fully compatible with popular md5sum utility for MD5 and SFV (Simple File Verification) for CRC32. The program features: -- Possibility to recursive processing the subfolders; -- Possibility to set a mask for selection of files; -- Possibility to set a mask for selection of checksum files; -- Possibility to run in several modes: one checksum file for folder tree, one checksum file for folder or separate checksum file for each file; -- The detailed protocol of processing; -- Support the MD5SUM (Message Digest) file format; -- Support the SFV (Simple File Verification - CRC32) format; -- Remembers all settings and automatically restores them at the next launch; -- Support the command line parameters; -- Very simple and convenient graphic interface; -- Very small and fast (written fully on WinAPI);

QuickHash Library

A 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, blobs, streaming data. It is quick, flexible, easy to use. It supports 3 interfaces: QuickHash API (the API can be used as is, or it can be used to create wrappers for languages that can use DLL or LIB), C++ Interface (C++ wrapper classes to QuickHash API), and QuickHash Type Library (includes all declarations for accessing the functionality from programming languages that can reference a .TLB, such as VB 5.0, VB 6.0, VBA, etc). It allows static/dynamic linking. It has no external dependencies such as MFC DLLs, COM/DCOM or other component. The help file has C, C++ and Visual Basic examples showing how to add hash, checksum and HMAC calculations to Windows applications quickly and easily.

Directory Report

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 or HTML file. Prints AVI,MP3,MSI,WAV info. Prints cyclic redundancy checksum CRC. Finds duplicate files. Multiple file rename. Multiple file change date. Multiple file change owner. Shows file owner. Reports total file size grouped by file owners. This shows who is hogging all your space. Finds and processes NTFS streams

DirSync Directory Synchronizer

DirSync is a powerful tool designed to backup or synchronize files and folders smartly and quickly. It support run as service, bi-directional sync, scheduling, log, simulation, filtering, path variable and CRC32 etc. The synchronization is based on the policy user specified to copy those files which are different between source and target folders. Using DirSync you may define multiple jobs and execute them at scheduled time automatically and silently. There are many situations of using DirSync. For example, you can backup local working directories to safe place in a server, deploy or distribute files from one location to many other computers, synchronize data between desktop and laptop, backup your working data to external USB hard disk or flash disk etc. Features of DirSync: (1) Run as service (2) Job scheduling (3) Bi-directional sync (4) Simulation mode (5) Dynamic running info and detailed log info (6) Support path variables (7) Multiple filter types: include/exclude files, exclude folders, date, size, attributes (8) Support CRC32 comparison and validation (9) Use intermediate file while copying (10) Command line parameters (11) Thread priority (12) Error handling mechanism

Duplicate Finder

Find and Remove TRUE duplicate files, Search duplicate file contents regardless of file name, Delete or move duplicate files, Clean up disk space, manage files better, Duplicate Finder matches byte by byte or CRC32 to give you most accurate results. Faster and more reliable than other duplicate file finders. Features 1. Two powerful search engines (byte by byte and CRC32). 2. Find files with same contents, same name and zero size. 3. Find duplicate pictures(jpg, gif), video(avi, mpg), songs(mp3). 4. Fastest among duplicate file finders. 5. Very user friendly, Specially design for novice users. 6. Works with removable media devices like Floppy, USB, etc. 7. Search local PC and over network. 8. Find duplicate files based on criteria : filename, byte to byte, contents, etc. 9. Can find duplicates from a selected set of folders (i.e., not from whole drive). 10. Allows important folders you wish to be excluded from scanning altogether. 11. Can use wild cards. 12. Protects the windows and system folders. 13. Skips the hidden files and folder. 14. Show file versions and properties. 15. Picture Viewer. 16. Save search session for future searches. 17. Results can be exported in two formats HTML and CSV.

Iside compares files and folders by computing their hash code (MD5,SHA1,CRC32,...). Right click on a file, select Copy and by right clicking on another file you will discover if the two files are equal. Includes file comparison, hash generating tool plus a complete folder comparison tool. The hash function is the fingerprint of file. It allows to determine if two files are different even if their size is the same. Ideal tool for configuration managers, programmers, deployers. Useful also to compare photos, music and movies downloaded from Internet. It can also be used for file integrity checking.

CDCheck is utility for prevention, detection and recovery of damaged files with emphasis on error detection. It can check each your CD/DVD (or any other media) and indicate which files are corrupted. CDCheck reporting features tell you exactly where the problems are. Files on CDs, zip drives, USB keys etc. can get damaged in a number of ways, so the program helps you determine whether your data is safe before it's too late. The program also provides extremly fast binary compare for effectively checking that file transfers (burning, copying...) were accomplished successfully and alerts you of differences. Besides that CDCheck supports creation and checking of MD5, CRC-32, SHA... hashes in SFV, MD5 and CRC file formats. This provides means to check backups for possible loss of information or verify file transfers where comparing is not possible (transfer over mail etc.). The program can be used with all local or removable media (CDs, DVDs, disk drives, floppy disks, ZIP drives, USB keys...) visible by the operating system (Windows Explorer) and also with audio CDs. In addition CDCheck also gives detailed information (manufacturer, type, capacity...) about inserted CD or DVD media.
