I've just lost a document which was nearly 300 pages. I got deep into the work and didn't stop to save! :-( Of course, as I'm three pages away from finishing this huge document, Acrobat crashes (for the first time since I've had the program, might I add!). Luckily I remembered that I have the program set to autosave every 5 minutes! I googled and searched through the forums here looking for a way to access the autosaved files, but all the tutorials with the file paths seemed to be for earlier versions of Windows than mine (I have Windows 10), so with the different file paths, I wasn't really able to follow those tutorials. I decided to get onto the support chat, only to be told that the Acrobat AutoSave feature does absolutely nothing and that this is an issue which Adobe is aware of, and apparently has been aware of for some time. I asked if they made any kind of announcement, and the support chat agent confirmed to me that there was NO announcement of any kind about this issue. I was very disappointed to find that there wasn't even a mention from Adobe about this issue, because that's something that's extremely important, and in my opinion, it's quite deceptive to let people believe that when they're choosing their autosave options, it's actually automatically saving when it is not.
In short, I'm really making this post so that other users are aware of this issue, since I was told by a representative that Adobe made on mention of it.
