File-Sequence

A Powershell module for handling file sequences.

Created primarily to tinker with learning windows shell scripting while also being useful for some basic CG/VFX tasks that I would normally handle with python tools. In its current state it's mainly useful for frame checking, to make sure a sequence hasn't dropped any frames during render/upload/download/transfer/etc.

Installation

Clone into your Powershell Modules folder.

Usually C:\Users\USERNAME\Powershell\Modules
