Since 2.1.9 the windows version of TexturePacker also comes with command line support (I had no time yet to implement file globbing using e.g. *.png) But you can use dos batch files to help you with this.
First you need to add the TexturePacker's bin directory to your path. Here you find 2 versions of TexturePacker: TexturePacker which is the command line version and TexturePackerGUI which is the "old" graphical user interface.
Updating all your sprite sheets at once
With this simple batch file you can update all sprite sheets from the settings in the *.tps files in one folder:
@echo off for %%X in (*.tps) do (C:\Programme\TexturePacker\bin\TexturePacker.exe %%X)
Mass conversion of files
Write a simple batch file containing these lines to do as mass conversion of images:
@echo off for %%X in (*.png) do (C:\Programme\TexturePacker\bin\TexturePacker.exe <parameters> %%X)
<parameters> with your parameters needed.
