So... I was given an almost-new iPad. Nice size, good colors, looks neat. After some minor wailing and gnashing of teeth, I finally got it connected to my wifi at home, so I can get on the Internet with it. Good start. Note: I've been using DOS/Windows since the mid-80's. So by now I'm pretty well entrenched in the Windows scheme of things. I have tons of schematics, for example, under a Peavey sub-directory, with a folder under it for "Triumph 60" for example, and in that folder will be schematics, pictures, Word documents, perhaps a spreadsheet. My whole computer is set up that way: in the Band sub-directory, I have various folders, including one for "song charts" with pdf's, Word documents, perhaps a jpg or TIF or two. Okay, now I've got this nice little iPad. I figured it would be great to copy all my schematics and song charts and tube books and whatever onto it, I could take it down into the basement workshop when working on an amp, or out to a practice where I could call up the song charts. Only...it doesn't appear I can do this. The iPad (with the iOS) does not seem to be capable of organizing stuff under directories and folders with various stuff in there. Yep I could slowly and laboriously use the clumsy iTunes and the USB cable to copy the PDF's...to where? All lumped together, like it did my mp3's?? Yep, THAT's really helpful to have a couple of thousand PDF's all lumped together. Or pictures, or whatever. I dunno. I fail to see the Apple scheme of things. Am I missing something? Looks like they just made this thing to play songs or videos or take pictures or get on Facebook. Any iPad experts out there who can help me make this thing do some real work? I need folders set up like Windows, and to be able to put files of all types in each folder, and call them up easily. Not keep stuff lumped under an "app".
