Today I had to find all JPG files over a certain size in a large directory tree of a few thousand images, to find some poorly compressed jpg’s, fix the compression, and replace them on a website. Todays cavaet, the CMS is pretty weak and only lets you update 1 image at a time, so you can’t just blindly resave everything and reupload, todays Second cavaet, I dont have server level access to said website, so all the normal automated ways are out of luck.
Anyway! the code:
It searches through a directory tree of your choosing
for any file matching the filetype: “jpg”
that is above a size threshold: fileSizeThreshold (In this case, 2kb.. so essentially everything)
and outputs it into an excell sheet with full path and size information
so that you can easily Sort, Filter, Delegate, or use as data for further automating!

A couple simple tricks you can do with the remote process execution of the Slave Utils for fun. (Also corresponding commandlines for use with the psexec, which is what the slave utils is batching
you can start a remote command line on any of the machines in your list simply by doing a cmd.exe in the ‘ProcessToStart’ line.. its a small thing, but its helpful for certain things.. ie: copying files from one remote machine to another remote machine.. its *MUCH* faster if you do something like that FROM one of the remote machines, and skip the middleman.
How to start VNC on a remote machine, and have it work interactively… when you’re not allowed to install it as a service! (Read: Our IT uses its own copy of vnc that we aren’t allowed to Co-Opt for our own uses.. so we end up with 2 copies running!)
Apparently its tricky to run interactive remote processes that are allowed to interact with the desktop under full local privileges?! Go figure. Anyway, This is what you would enter to launch the vnc with the same privileges as if you were at that computer and hit the shortcut.
cmd.exe /c start “c:\program files\Realvnc\winvnc\winvnc.exe” “c:\program files\Realvnc\winvnc\winvnc.exe”
what this converts to in actual command line is something along the lines of:
psexec \\computer -i -d -u DOMAIN\Login -p password cmd.exe /c start “c:\program files\Realvnc\winvnc\winvnc.exe” “c:\program files\Realvnc\winvnc\winvnc.exe”
so it used the login and pass to launch the remote cmd.exe, but then used the local system privileges with the start command. allowing it to have full network and desktop interaction privileges.
More to come later.
- Run the .HTA once.. it will create 2 files for you
- “Computers.ini” which you will will need to edit to contain 1 slave computer per line in it (either IP address or computer Name work, use 127.0.0.1 for your local system)
- “SlaveutilsOptions.ini” which will have slots for various paths and options. read the file and edit the lines accordingly.
- (Path to your VNC client,
- whether to use alternate credentials or not,
- and what the login/password would be if you did use them.
Note: Its been brought to my attention that some virus scanners will flag this download (Understandably in my opinion) as ‘Greyware’ because it contains VBScript that uses the WMI (Windows Management Interface) to affect changes to remote computers, enclosed in an HTA (Read: Executable Webpage). the full code is in there and easily readable.
I’ve been experimenting with a few other ways to package it, either via Maxscript, or Python, but they tend to get constrained to ‘free’ time as this functions perfectly 🙂
