I'm using 1.6.9 of the Arduino IDE under Raspbian Jessie on a pi2. For some reason it persists in duplicating some open files in the project and then randomly, it seems to me, using one or the other file in the build. So I thought I'd back things up in a subdirectory and delete the extra tab. It not only deleted the tab, it deleted the back ups in the subdirectories, all the files in the project directory and then bombed out to the prompt. Thankfully I did recently print everything out and a few files are copies elsewhere but they aren't current as of today.
It seems to me that none of this should be possible. Why does deleting a tab delete the entire project? Why can't I stop multiple tabs from existing for the same file, which are not the same information but aren't saved as a separate file? Why can't I just close a tab? Why can't I just add a file instead of already having to create it elsewhere and then search it out to add it? Does 1.6.10 address any of these issues? Thanks.
I have never heard of that sort of behavior before - that's wacky - I strongly suspect that what was actually done is inconsistent with what was written above. The voices in my head say that you moved the files instead of copying them when you backed them up and fatfingered the move operation and put them into a subfolder of the folder you intended.
From the sounds of things 1.6.10 is a really bad release - avoid it like the plague. This is Arduino - you should never upgrade the IDE version without checking what people are saying about it on the forums. Of the past 11 releases (the 1.6.x versions), only 3 have been good( 1.6.3, 1.6.5r5, and 1.6.9).

For that to be true, the files that are backed up would need to be the current files, which they aren't, and there are no subdirectories there and those are gone from the project directory that is now blanked. Also, the IDE bombed out the instant after I deleted the doppelganger of the original project file, I did the backup outside the directory yesterday. I was backing up inside the directory in a subdirectory more recently, those are all gone.

I'm not super happy with the 1.6.9 I'm using either. Is it possible I'm seeing these issues because I'm using more than one file in my project? I've got, or at least I had, right about eight files open, four were cpp and four headers. The doppelganger thing started right off the bat when I added a second file, I think it was.
