@burnout426 Thanks for tips. Unfortunately, I closed my browser after it has crashed. Now, I will save my tabs frequently not to be worried in the future.

@huna7a Thanks for reply. It hurts to say that I might try other browser. I have been loving opera for over 2 years now. I love its features, messenger app and other stuff on the left bar, pop-out video, and far most, that the session open every time after it closes. The new grouping folders on the left bar, this is really great. I wish it was more stable, like in the past.
Cheers!

Hello,
today my Opera and whole computer crashed. My PC restarted itself without a reason. After that my opera session has disappeared.
Every day I open 3 opera windows, each with multiple tabs.
After my pc had crashed,

1. I opened opera and wanted to recover my tabs by clicking CTRL-SHIFT-T, but it didn't work
2. I searched the forums to solve my problem, but I couldn't find a solution.
3. I searched the local files and found promising files:
   AppData->Local->Opera Software->Opera Stable->Cache and Media Cache
   In both folders I have 1000+ files names f_00000a,f_00000b,f_00000c etc.
   But I can not do anything with them.
   4)Another location concerns the session folder:
   AppData->Roaming->Opera Software->Opera Stable->Sessions and Session Storage
   I've done a copy of that folders before doing anything.
   I found there many files
   
   Look at the Date and File Size
   Files before 13:37 are bigger than younger ones. I assume 13:37 was the moment before the crash.
   I tried renaming the files, opened them but I couldn't help.
   I really don't know what do to. Please help me restore my session.
   Also I can not use history tab since I Used opera in 3 separate windows, sometimes I didn't use the others, thus not all tabs appear in the history. To be honest, I would search my history deeply If I have no other choice.
