A lot of my friends now use tablets or iPads for both songs and sheet music: one of them has a foot-operated "page-turner" for music scores that are more than one page long, tho she did say that device cost almost as much as the tablet.
For any instrumental concerts we do with a pre-decided set list, I insist that everyone puts all the (relevant only) sheet music (if they need it as some do) in set list order in a single folder - a pretty basic request but apparently an alien concept to some! No frantic shuffling thro several folders to find the right pieces, or worse still, piles of loose paper that inevitably scatter themselves randomly all over the floor and hold us all up while disarray and disorganisation is on show and restored to order!
I have an iPad and would like to transfer more stuff on to it, either to iBooks or Pages, but seems it's one file at a time. Is there a way of transferring whole sub-folders in a one-er? Maybe some of the suggested software above can do it?
