Once again my “toolbox” earned its place in my pocket. I have a USB drive (literally renamed Toolbox) that’s loaded with batch files and test programs for computer maintenance. Today I used a batch file with the dism(dot)exe command line tool, with some of its variables, to free up disk space on a client’s computer. Instead of looking up the variables each time, or trying to memorize it, I store it in the toolbox. Today it recovered several GB of space not retrieved by the Disk Cleanup utility.
