ipod large file

Is it possible to delete a music file on your computer, and still running in iTunes or your iPod?

I downloaded an album to put in my new iPod, and deleted the file later. The next time you synchronize, the file does not work. I guess because I've deleted. Is there any way around this? I ask because I'm on a laptop and has no memory in this sense, it is not possible for me to have thousands of music files at the same time.

First place, never use the sync option in iTunes. You can set a place where he does not sync automatically, manually manage songs and she said something. Therefore, to obtain pieces of the iPod, it seems that using iTunes to download your music, I think you just need go to your list of songs downloaded from iTunes, select what you want, and drag it to your iPod on the left and adds synchronization alone without them. Anyway, I think it should, I think is the automatic synchronization or click the Sync button thats spoil it, then turn off auto-sync and do not press the sync button and it should go:) But once that only in the iPod are not sure how to get it on your computer, you may be able to drag the iPod into your iTunes library. I personally would not shock me music with iTunes, I use gomusicnow.com is much cheaper. And if you have a USB external hard drive, you can store all your music on the spot and not worry about the hassle export and import into the iTunes library. With gomusicnow, you get the MP3 Straits and can be moved like any other computer file, is not limited to iTunes so might think that:)
