MD5 File and Folder Comparator is for comparing files as to whether or not they are identical in content. A pair of files may be compared, or all files in two subfolders (optionally including files in their subfolders). Comparison of files in folders may be done to display files which are the same or files which are different. A listing may be obtained of all files in a folder (and optionally subfolders) with their MD5 digital signatures.
MD5 File and Folder Comparator works by comparing the MD5 digital signatures of files (using the MD5 message digest algorithm). The MD5 digital signature of a file is a sequence of 16 bytes, usually displayed as 16 hexadecimal numbers with no intervening spaces, for example, 4EAE15241AD90F85D038523E9D14DDDB. Two files whose MD5 digital signatures are different differ themselves in at least one byte. Two files whose digital signatures are the same are identical in content, except where the two files have been deliberately constructed so as to have the same digital signature. Such ''collisions'' are extremely rare, and in practice two files whose digital signatures are different are always themselves different.
Here are examples of possible uses for this program:
1. Comparing two versions of a file as to whether they are the same or different.
2. Recording the digital signatures of a set of files to be sent to someone else along with those files, so that they can check that the files they receive are the same as the files that were sent.
3. If you have backed up a folder and its subfolders to some external device and later you wish to check which files in the source folder have changed then you can compare that folder with the backup.
4. If you have two folders, each of which is a backup of some other folder, you can use this program to get the average of the file dates in each of the backup folders, thus telling you which backup folder is latest.

The Modified File Backup software ("the Software") consists of the executable file and the other files installed by the installation program mfb_setup.exe obtainable from the Hermetic Systems website.
The Software is protected by copyright, which is owned by Hermetic Systems. The Software may be downloaded from the Hermetic Systems website or another authorized download site solely for the purpose of its evaluation with regard to the purchase of a user license. Neither the installation program nor any work derived from it may be distributed further by any means (including via CD or the web) without the permission of the copyright holder.
All intellectual property rights related to the Software are owned by Hermetic Systems. You may not rent or lease the Software. You may not modify, translate, reverse engineer, decompile or disassemble the Software or any part thereof or otherwise attempt to derive source code or create derivative works therefrom. You may not remove, alter or destroy any proprietary, trademark or copyright markings or notices contained within the Software. You may not sell or offer for sale any derivative work. Any rights not explicitly granted by Hermetic Systems are reserved.
In return for a license fee paid to Hermetic Systems or to one of its authorized representatives or resellers you are granted a license to use the Software in its fully-functional form and you are provided with activation keys for each installation of the Software as follows:
(A) If you are a natural person then you receive a single-user license and this entitles you to install, activate and use the Software on a reasonable number of personal computers (laptops and desktops) in your private household or office.
(B) If you are an entity other than a natural person (e.g., a corporation) then you must purchase either (a) one or more single-user licenses for each installation, activation and use of the Software (discounts are available) or (b) a site license, which allows multiple installations, activations and uses, and which is expressed in terms of the number of activation keys which may be obtained. (Contact Hermetic Systems for further details.)
The function of an activation key is to remove any temporal or functional limitations on a particular installation of the Software. A separate activation key is required for each installation (in other words, an activation key works only on a particular computer).
In the event that a later version of the software is released, you may update an installation at no charge by downloading and installing the new version.
If you change your computer (or make a major hardware modification) you may need to obtain a new activation key. This can be obtained at no charge via a web page (there is a link in the trial or demo version of the software), provided that, in the opinion of Hermetic Systems, the number and frequency of such new activation keys is not unreasonably excessive.
Installation of the Software constitutes an agreement that the Software is provided "as is", without any warranties or guarantees. Hermetic Systems makes every effort to ensure that the software is error-free and performs as stated in the online user manual, but does not guarantee this. You assume responsibility for selecting the Software and using it for your intended purposes. In no event shall Hermetic Systems, its resellers or distributors of the Software be liable for any damages whatsoever arising out of use or inability to use the Software, even if advised of the possibiity of such damages.
This software performs file deletion under user control. Hermetic Systems, its resellers and distributors of the Software, will not be responsible for damages of any kind arising from loss of data resulting from unintended deletion of files.
