Is there a preference I can check if I do NOT want anything to be grouped?
Many times when I’m dragging from one folder to another within Scrivener or from another folder on my computer to Scrivener, whatever I dragged gets grouped with something in target folder.
It’s time-consuming to constantly have to ungroup… 
Thanks,
By grouping, I presume you mean the item gets dropped inside an existing container or item? If you need to drag in between things, not onto them. Try moving slowly and carefully to examine how the drop cursor changes as you do so. If an item is circled, it will be imported as a child to that item. If the drop indicator is a line between items, then it will be inserted as a sibling between those items.
Let’s say I have an image and I want to drag it inside a folder which has several images already in it.
What happens many times is that instead of just going inside the folder it gets put on top (or maybe under) another image in that folder
(same thing happens with text)
I see a circle on the left end of the line-- is that what you mean?
so, other than moving a bit more slowly, there’s no solution, correct?
Yes, the line with a circle on the end of it indicates it will be placed in between those two items, at their same level. The depth of the circle indicates the indent. That will ordinarily not be under your control unless you are at the very end of an indented list, then moving up and down slightly will cause the circle to indent at various levels.
I suppose yes, going more slowly is the answer, though for myself anyway, this just came with practice. It might depend a bit on motor skills and how accurate the mouse is, but once I got used to the sense of space defining “in between” I found it easy to hit the target I was moving for. At any rate, if you find using the mouse a bit unwieldy, there are keyboard shortcuts for moving things around in the outline. Ctrl combined with the arrow keys will move things up and down, and to different indent levels, respectively.
You could also right-click and use the Move To command from the menu to just select the folder you want to dump into, then use the arrow keys if you need to rearrange the items within that container.
I use a wacom pen, which is more accurate than the mouse, but the issue is that my monitor set at a super high resolution for working on big images in photoshop, so in Scrivener the space between two graphics (or 2 text files) is pretty small.
The control keys won’t work if I’m dragging from another drive, but your tip about the circle will make it easier to know when I’m on target. ( I hadn’t noticed that) So now, I’ll look for that when dragging
Thanks,
Ahah, good point, I was thinking about moving within the binder. Hopefully then Ioa’s tips will be enough, but if you’re still having trouble with this, you can always import the long way, by selecting the parent folder and then using File > Import.
Oh, or another option is to open the parent container on the corkboard or outliner, which may give you some additional space to work with–then just drag and drop into the empty space in the editor to import into that container.
Ah! Excellent suggestion. Can’t believe I didn’t think to drag into the corkboard.
Doh! Feel like Homer Simpson… 
Thank you Jennifer
Ah yes, I forget about that as well because the Mac version doesn’t have that feature yet. Take care that in the Corkboard you can still drag things into other things, if the “Allow dropping dragged items onto cards” is enabled in the Corkboard options tab. That is off by default, so it shouldn’t get in your way, but if you did turn that on so you can drag cards into other cards to group them, you’ll want to notice that the same sort of symbolic drop icons are used on the corkboard, they are just bigger and easier to hit. A line in between cards vs. a bubble around the card.
Dragging into the corkboard is SO much easier than what I was trying to do, and it seems to work whether the “Allow dropping dragged items onto cards” is enabled or not.
Thanks for the tip
