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:

• 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
• Do I have enough room to copy source -> dest - copy oldest files first
• Implement create directory if not exist routine
• Cleanup the code
• Make dest drive setting value

Perl Script

use File::Copy;

my $podcastsource="C:/Documents and Settings/Mike/My Documents/My Music/Podcasts";
my $podcastdest="J:/MUSIC/Podcasts";
my $dircontents=();
my $destdir=();


print  "Checking files to move over.\n";
&move($podcastsource); #Check what is in the source and not in the dest - copy to dest
print "Checking files to remove from On The Go.plp\n";
&OnTheGo;
print  "Checking files to remove.\n";
&smash($podcastdest);  #Check what is in the dest and not in the source - del from dest


sub OnTheGo
    {
    $LOGFILE_IN="J:/PLAYLISTS/On The Go.plp";
    open LOGFILE_IN, $LOGFILE_IN or die "Cannot open $LOGFILE_IN for read :$!";
    #binmode LOGFILE_IN;
    
    while (<LOGFILE_IN>) 
        {
        
        my $tmp=$_;
