MD5 signatures are 32 hex digit strings derived from (binary) files by a highly specific algorithm. Files that differ only slightly have completely different signatures. Also, it is really extremely unlikely that two different files have the same signatures.

MD5 signatures can therefore be useful to verify the integrity of files e.g. after copying. The two utilities presented here enable you to make and check signatures in an easy and quick way. 

Download setupMD5x.zip, containing setup files for:
MD5Maker (version 1.8.12.7)
MD5Verify (version 1.9.7.3)
The size of the zip is 1.60 MB (1,683,774 bytes).

This pack contains the latest updates (version history to be found at the Forum). They have been tested for Windows Vista, XP, 2000 and 98. Installing a newer version is automatically preceded by an uninstall procedure.
For the MD5Maker, you first have to log off, then log on again, in order to make a complete uninstall possible. Take notice that the uninstall utilities do not know the correct version numbers of the MD5Maker and the MD5Verifier present on your system, so just ignore the version numbers displayed in the messages!

The MD5Maker can be started from the Explorer's context menu when you right-click on a selection. MD5 signatures of ALL the files in this selection - including the files in its directories and subdirectories - are calculated and stored in the MD5 Signature File.

The MD5Verify program has the MD5 extension associated to the program. This makes starting the program possible by double-clicking on an MD5 Signature File. All signatures are checked against the corresponding files.
Both programs support drag and drop. Read the explanations below if you want some quick information.

As an example, the signature of the pack is:
5a3b6b18175c1177044acae50b7ce73f *setupMD5x.zip
