Now, they say anything deleted on a Chromebook is gone for good, but I haven't zeroed out anything, which means that that's probably not entirely accurate. Especially since the hard drive I deleted things from was external, which means I can and have removed it, which means they're not going to get overwritten (unless they already were, which would have needed to happen almost immediately.)
The thing is, though, you can't just install shit on a Chromebook. It needs to be Chromebook compatible which most things aren't.
Right now, everything but the Chromebook is out of commission, which means that if I want to recover those folders, and the files they may or may not contain, I need to do it using the Chromebook.
So, we come to the question: How do I recover erased files on a Chromebook?
Please remember that I am well aware that there's no native function for doing that. I'm not asking "Where is the Recycle Bin so that I can take the files out?" I'm asking, "The files are well and truly deleted but have (almost certainly) not been overwritten, given that, how do I get them back?"
Basically what I need here is either "This is an app on Google Play that is simultaneously: capable of doing the job and Chromebook compatible" or "Even though you know nothing of Linux, you need Linux. Here is a step by step --leaves out no details no matter how obvious they may seem-- process to recover erased files with the version of Linux you can install on a Chromebook."
The Linux thing is in the beta stage right now, which means it might not work completely properly, but this is the key thing: it used to be that you had to swap your Chromebook into developer mode to use any Linux thing whatsoever, and that process can (apparently) erase every fucking thing you have. The beta stage "install Linux with the push of a button" function doesn't require any such tinkering, and is relatively risk free.
It also doesn't give you much in the way of control. There are literally no options. You push the button, it installs Linux, and you have no input on what that actually means.
(Even if you can't help) if you're reading this, thanks.
* Important stuff not actually from the Chromebook, I was supposed to be copying something, but instead I moved it, when I noticed the mistake I canceled the move, and I was undoing it, but the Chromebook didn't merge the relevant folders so I took a look inside to manually movie the files in the folders into the places they were meant to be, and didn't find any files to move.
I deleted the seeming superfluous folders, and only then did it occur to me, "There might have been hidden files." I checked, and (sure enough) hidden files were hidden, so I have no idea if I deleted any or not.
