Keep An Eye On System Changes With TheFolderSpy


TheFolderSpy monitors folders so one can check for changes. The Spy in the name may conjure up a hesitation or two and the program doesn’t help the cause by having hidden and incognito modes.  In these modes the program runs in the background. However the hidden and incognito modes don’t really make the program invisible, both leave the program’s icon in the tray area, but notifications are disabled in the latter.


Perhaps the best use for TheFolderSpy is to keep an eye on programs that add folders or files in places like the Documents folder when they are being installed.

Using TheFolderSpy starts with adding an item. Choose the path to the folder – and optionally subfolders – to be monitored, if needed add file type filters and optionally execute a file when a change is detected. Created, changed, deleted or renamed are the file attributes that can be monitored.

TheFolderSpy can be paused, made to save a log or start with Windows. It has a built-in feature to send emails when changes occur. The email feature is ready to use with gmail or any other SMTP server. The subject and content of the emails can also be set within TheFolderSpy.

TheFolderSpy has command line parameter support to configure its modes, log file path and others. The email body has parameters as well. For example *f inserts the file name and *n the date and time of a change (See the accompanying readme.txt for others).

TheFolderSpy is freeware, a single executable file, just over 60KB and runs on XP and newer versions of Windows. It requires .NET Framework 3.5.


  1. Apart from its dull interface TheFolderSpy is not a bad application, it is tiny, portable and has a good set of features. Yet there is a lot space for improvement. For example I didn’t find a way to minimize it to system tray only, when it is minimized it resides both in task-bar and in system tray which is not to my taste, I would prefer to have it minimized/closed to system tray only (my system- XP SP3).

    Happy holidays!

  2. Asen, I believe clicking Run in background minimizes it to tray only.
    Happy Holidays, thanks for the comment and the social media Like and follow too.

  3. Thank you for the tip! I have missed this option during my superficial testing (I am not saying this as an excuse, but at least for me the interface is not very intuitive, or perhaps I am too much used to check-boxes minimize/close to tray).

    I like you blog very much, indeed. Your reviews are short and to the point and here I have discovered lost of interesting applications. So your blog is among the tech sites I follow via my RSS client.

    Cheers and all the best,
