Yesterday, Opera updated itself to Opera One, or whatever the new version is called. I mostly got used to the new interface, and at some point I also poked Manage Workspaces with a stick to see if they had added more choices of workspace icons, but didn't change anything.

I fired up Opera today, and noticed that the Workspace at the bottom of my list of Workspaces was now completely empty. It had a large number of pinned tabs and whatnot on it. I'm pretty sure that one was okay (that is, intact) last night when I quit out of Opera and shut down my Windows 10 machine, in fact I had just added another pinned tab to it not too long before shutting down, say within an hour or two before shutting down.

I do not know why it would have cleared that space out entirely, and I am hoping the lost tabs are stored in some sort of recent-history part of the stored settings and/or history files. All the rest of the Workspaces are completely intact, so far as I can tell.

How do I get the stored tabs back for that now empty Workspace?

It just did it again! 0O

I have 11 workspaces open. I had 10 of them before, and when it deleted all the tabs out of that 10th one, I made a new one below that one to house some of the pinned tabs I managed to rediscover, while I tried to see if someone could discover how to recreate from internally saved data the ones that were in the 10th workspace. Now it's spontaneously deleted everything out of the 11th workspace. Apparently there's a bug that is failing to keep the tabs from whatever the bottom-most workspace is. This is aggravating. Has anyone else been having this infuriating malfunction? 0o

@leocg Okay, found some files named Session_[string-of-numbers] in the currently active Sessions and some others in the preserved Sessions from the older Opera Roaming folders. Looked inside with with Notepad++ and a lot of it is NUL NUL NUL stuff, though I can make out some web addresses imbedded occasionally in a sea of NUL NUL NUL. Is there an easier way to examine the contents of these that's more user-readable wrt the addresses in there?

I am on Windows 10 Pro 64bit, I am on the latest Opera version 78. It Just updated to the latest version (Version:78.0.4093.112) before I posted this, so I was on whatever version number I was automatically updated to before that when the below-described happened.

I have 8 different Workspaces set on my Opera, each one with a large number of tabs pinned. Two of those, I have a long list of Youtube channels of various sorts pinned, along with channels at several other video-hosting places.

Today, I fired up Opera like usual, went off to do my usual activities in it... But also, at some point, I glanced at a tab saved from the previous night that was of a Youtube channel I'd just found the day before, but upon opening the tab this session, I discovered that the tab now pointed to the Youtube mainpage instead of to whatever the channel page was. I was now looking at the "Oh, look what random new videos showed up today!" page. I shrugged, and figured I must have accidently dragged over the wrong tab from the other Opera window last night, and so I closed that tab and went back to what I was doing before.

And then several hours later, I went to go look at one of my two. dedicated Opera Workspaces for saved video channels... and suddenly realized that more than half of my saved Youtube channel tabs were now pointing to the Youtube mainpage, and Not to the Youtube channel I had pinned on the particular tab. There wasn't any go-back history recorded for any of those tabs, either, so it's not something where it got redirected to some other page From that saved channel page... or if it did, it was something that happened in a way that overwrote the web address history for that tab. The bizarre thing is, it seems to have done this replace thing on only Some of the stored Youtube channel tabs, completely at random. But it happened to more than half of them.

I do Not know what happened here. All I did was turn the machine back on for the day, fire up Opera and let it load all the saved tabs and stuff from when I last exited out of Opera... like it has done successfully for many, many months without issue.

This lost-tab-addresses thing Might have something to do with the fact that my Internet connection has been randomly going up and down briefly all day for the past 2 or 3 days, causing pages to give me a "This page cannot be reached" error at random throughout the day, where maybe 10 or 15 seconds later the page loads again like normal.

The other bizarre thing is, this lost-channel-address thing seems to have happened only with Youtube. It has Not happened with any of the other massive number of pinned pages I have, such as ones pointing to web-forum pages or to online-shopping product pages I have pinned. I do Not know if this malfunction is something Opera did, or if this malfunction is something Youtube did.

Thing is, I need to find a way to retrieve those lost Youtube channels and get them repinned. I have a set of folders I drag-and-dropped desktop shortcuts into for lots and lots of Youtube channels, but I don't remember which ones out of those I had pinned, and in what order, but a large number of them I had pinned in more or less the same order going back months, and I also have an older copy of my Opera settings folder from Roaming preserved from back in May... my problem is, try as I might, I cannot locate whatever file it is in there that contains the saved, pinned tabs and stuff. My understanding is that there's potentially supposed to be a folder or files named Last Session in there, and the like, but I'm not finding those in there anywhere, or anything else that looks like it simply has my saved tabs' addresses in it from back then, nor can I find anything like that in the existing Roaming, either.

I am at a loss. I do not know why suddenly, over half of my saved tabs for Youtube got borked like that, or what to do to get those saved addresses back where they're supposed to be... manually (by seeing them on a list and simply loading the particular channel again and positioning the tab back where I want it) or from some incrementally-saved backup.

I guess what I'm mainly asking is: Where exactly Are the addresses of the tabs saved to from session to session that I could examine the contents of (i.e. in Notepad++), and is there some other way to retrieve this info from my Opera history?

At that, I could have sworn that at one point in the past, it was possible to scroll back into the History pane and, in addition to showing the pages you'd navigated to as you went along, it would show all tabs loaded back in at each session-startup, but I'm seeing no indication of that in there now.

Okay, I have a whole bunch of stored, pinned web-links in several Workspaces in Opera. A good number of those are of various Youtube channels. Today, for some reason, 90% of these got replaced with a link to the Youtube main page, instead of the channel I had pinned, with no way to get back to the page I had pinned (no back-history or forward history on that tab).

I have an older, stored copy of the Opera folder from Roaming, but I cannot figure out where in there all the pinned-tabs stuff is stored, and some of the files in there I gather from other how-do-I-do-this searches that might contain some or all of that info don't seem to be present, for instance I don't see any kind of Last Session folder or such.

I literally just went to refresh my memory as to what Youtube channel I had in tab 1, 2, 3, 4, and so on for the couple of Opera Workspace panes I had set up for that, so I can load them back in from saved desktop-shortcuts again and pin them there again. You'd figure this would be trivially easy to locate.
