media_copy

A heavily commented perl script that you can customise to copy photo and video files to your hard drive according to your own media file storage scheme.
You need to be able to hack perl code to adapt this script for your own use, otherwise look at program "Rapid Photo Downloader".
The initial setup creates folder and file names with date and time, and duration for video; but the point is that you can adapt the code to use any of your files' metadata to build your file names. The metadata are extracted by the excellent ExifTool library.
A jpeg thumbnail is optionally stored for each video file.
