advanced-checksum-verifier is an value calculated from a content of file by special algorithm. This algorithm is designed so that change even only one bit in the file data will cause the absolutely different checksum value.

Another good feature of the checksums is the fixed length of the checksum irrespective of the size of an source file. Unimportantly, what was the size of source file - 1 kilobyte or 100 megabytes, the length of the checksum always will be small. For example, 32 bits for CRC32 or 128 bits for MD5.

These features of the checksums may be used for revealing the damaged files or compare two files for identity. The good form considers granting to users of your files also the checksums of these files that they could check up integrity of files. Advanced CheckSum Verifier will help you in this. And presence of freeware XCSV utility will allow your partners to easily check up integrity of received files. The link to XCSV you can find out on main site page.

The Advanced CheckSum Verifier is an handy and fast windows utility for verifying integrity of files by using the CRC32 or MD5 checksum calculation algorithms for Windows users.

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. And hence may be used as GUI driven replacement for MD5SUM utility by Windows users.


advanced-checksum-verifier Main Features:

---

Recursive processing of subfolders

The program can recursively enter into all subfolders of the specified folder and calculate checksums of files in these subfolders. This feature allows to quickly calculate the checksums of files inside the ramified folders tree, for example on the entire CD, or on the FTP-site.

Setting a mask for selection of files for processing

You can set a mask of files for processing to not waste time on calculation of the checksums of unnecessary files.

Five ways of creating the checksum files

You may keep in one file the checksums for entire folders tree. You may create the separate checksums file for each folder. Yau may even create a separate checksums file for each file.

The detailed protocol of processing

The all information on a processing is accessible as the log, including values of the checksums of files. You may copy the entire log or its part to clipboard for further use. For the best perception of the information the warnings are displayed by different color in dependence from their importance.

Supporting the MD5SUM (Message Digest number 5) file format

The program create MD5 checksum files in the same format, which is used by the MD5SUM utility - the industry standard for MD5 checksum calculation. This allow easy exchange of the checksum files with another systems and platforms.

Supporting the SFV (Simple File Verification - CRC32) format

The another widely used checksums file format - SFV (Simple File Verification) is used for creation the CRC32 checksum files. This format very popular on the Usenet binary newsgroups and on MP3, MPEG4 exchange networks.

Very small and extremely fast

Written by using only pure WinAPI, the program is very small, has very low memory consumption and instantly start. The using of advanced low-level WinAPI programming techniques allow to extremely fast processing of files.
