NTDMatch v2.0.1.8 is a 32-bit native Windows NT/95/98/2000/XP program inspired by the DirMatch utility originally published years ago in PC Magazine. It compares directories based on filters which allow it to only show, for example, those files which exist in both, but the file in one has been modified. It allows file manipulations such as copy, delete, edit, etc. on all or selected files. It can be used to maintain floppy backups of the projects you're working on by matching the project directory with the same directory on the floppy and only having to copy files that are newer. It can also be used to take a 'snapshot' of the directories, which can be used later to compare to the same directory. This is handy for determining which files were changed when a new software package is installed. It is a specific purpose utility which doesn't try to address every feature of a file management package; however, it does what it does very well and is very flexible and configurable. It makes extensive use of the powerful NT control features.

If you ever need to:

• compare the contents of two directories (and optionally all of their sub-directories),
• copy and/or move files between these directories based on various comparison criteria,
• record a snapshot of the contents of a directory (and optionally all of it's sub-directories) for later comparisons,

then you'll find NTDMatch an absolutely super tool.

Here's one example of how to use this super function:

First, create a shortcut named "Snapshot Drive c:", which invokes NTDMatch with the appropriate parameters to create a snapshot file containing a point-in-time record of ALL the files and directories on your boot drive. All you have to do to record a boot-drive snapshot is double click on this object and name the snapshot file when NTDMatch pops up its file-save dialog (in which you may also enter an optional comment that describes the snapshot -- e.g., "Boot-Drive Contents Before Installing "XYZ" software, which will be put at the top of the snapshot file itself).

Then snapshot your drive before installing a new application. And, after the installation, record another one, using the same object (above). Then, using another shortcut named, "Save Delta Snapshot", almost automatically create a third snapshot that contains ONLY the changes that were introduced to your boot drive during the installation. You'd be surprised at what some applications do to your boot drives.

With these "delta" snapshots, you have a record of boot drive changes for EVERY application you've ever installed on a system.
