Off topic: Powershell to rename pictures

By Rikard Ronnkvist, 2010-02-07 15:53 Good-to-have, PowerShell

I’m trying hard to convert myself from VBScript to Powershell… so in the need of a powerfull filerenamer I wrote one in Powershell.

You need to download the Powershell Pack from http://code.msdn.microsoft.com/PowerShellPack

#  Will rename JPG and AVI files, uses EXIF-tag on JPG-images and filedate on AVI-files.
#
#  Files will be named:
#    \some path\YYYYMM\YYYYMMDD_HHMMSS_00.JPG
#               ^^^^^^ - Optional, if you have createSubdir set to True
