I wanna download some new music but my ipod’s running out of space. I really don’t wanna delete any single song, how can i backup them to my computer? They said I can copy the songs to anywhere on pc but that didn’t work at all, when ipod was pluged in there was no music(only some pictures) shown on...

I'm writting my paper and need to extract some paragraph out of pdf materials, but the pdf can not be copied, so I need to tranfer them to word so that I can use them freely. Any idea to do that? Do I have to use a software or any tools?
