Podcast Synch Batch File

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).

For the meantime, here is 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\"

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 copy
• Does file exist in dest and not in source - del dest
• Does file exist in source and not in dest - copy source
• Implement create directory if not exist routine
• Read the Sansa On The Go Playlist and delete files that are found
• Make dest drive setting value
• Check ID3 tag and set if blank - see &johncdvorak
