I have gathered a couple of years worth of Japanese language podcast lessons and they are taking up a lot of disk space. I would like to do the following and would like to know the best way to achieve the result.
1/ Move the old podcasts to external hard disk
2/ Have iTunes able to find the old podcasts when I connect the external hard disk to my MacBook
3/ All new podcasts will remain downloaded to my MacBook
4/ No damage to the iTunes music library structure
Thanks in advance for your help.
