Podcast Synch Batch File
From Mike Beane's Blog
Background
Not finding a good way to manage my podcasts on my Sansa e250 and I'm already manually dumping files from iTunes anyway (my choice).
Next step I plan to write something that checks:
- Cleanup the code
- Make a playlist (by directory or by group?)
Does file exist in both places - don't copyDoes file exist in dest and not in source - del destDoes file exist in source and not in dest - copy sourceImplement create directory if not exist routineRead the Sansa On The Go Playlist and delete files that are foundMake dest drive setting value- REMOVED
Check ID3 tag and set if blank- see &johncdvorak
Script Test
Pre-removal of the ANSI Win32 Color references. File:SubDir.jpg
Perl Script
Removed the MP3:: info/tag routines and also the Win32 references. That should make it cross platform.

BAT file
Here is an old synch.bat to del all files in the Podcasts directory on the Sansa and then xcopy everything in the iTunes Podcasts directory. It's not quick, but it works.
echo off cls del "g:\music\podcasts\*" /S /Q xcopy "D:\music\Ipod\Podcasts\*.mp3" /S "g:\music\Podcasts\"
Autoplay Handler
Under Windows, I added an AutoPlay handler (directions here). Now when connected, synchronization is possible from the popup window.
