endir.bat : if not exist "%1" endbat md zz call mov %1 zz\ call zren zz %1It puts an object into a dir with the same name as that object. This sounds silly but it's a super useful starting point for lots of things. For example, you have a bunch of music folders named :

Stupid Band Name / Ironic Album Titlea dir inside a dir. You just go "endir" on the original single dir, it makes a dir inside a dir. Now to do the rename you just truncate each name where you want it. (it's impossible to write a general renaming rule for this because people use all kinds of different separators; I've literally seen names like "And_You_Will_Know_Us_By_The_Trail_Of_Dead_Source_Tags_And_Codes").
