I have found varieties of this question. Most of them fall under monitoring and others are said to be buggy. A continuously monitoring program won't help me and neither will a list of the most recently modified files.

I would like to check if the directory, its sub folders and files have changed since my last visit. It seems to me that I'd likely need a program that maintains and index of that directory and compares it with its condition when I tell it to. Then that program could output to a log for my use.

This is on Windows 7 over a shared network, the folder(s) I'd like to check have 4-50GB of data.

I did find this, however I am still learning how to program. I think it describes what I want:

Thanks for considering.

The best way to check any modification in your system, in your case the folders is to use a Checksum software to do this. There's a lot of them so I suggest you to try these ones:

Nirsoft's HashMyFiles

Microsoft File Checksum Integrity Verifier (command line only)

or this utility more specific to folders

Nirsoft's FolderChangesView

Thanks for the suggestion, the Nirsoft programs don't work for me because I can't "monitor" the folder. The only MD5 hashing utility I've found that takes a recursive hash of a directory is MD5summer: . But it takes forever to calculate hashes on the 30,000 file directory I'm checking on from time to time. Is there a faster way to do this that doesn't require constant monitoring? – user1026169 Sep 30 '12 at 21:20
May be this one:… – climenole Sep 30 '12 at 23:28
this is a nice program too, but it uses monitoring. i need something i can check from time to time, not by constantly running – user1026169 Oct 2 '12 at 3:57
