Transfer from Win10 to Win11

I want to transfer my files from win10 to win11. I tried to use the thumbdrive but my files were too large. I also downloaded the Wave Browser,, but didn't like that. If I cancel my win10 and reinstall Thunderbird on my Win11 will it transfer? I'm looking for an easy method. I'm 83 and not that tech minded?

If you updated your PC from win10 to win11, the files remain on the PC. No need to move. Please provide more details on the status of your upgrade. thank you

No, I have a new pc a mini. I'm transferring from my old pc. Thanks for your quick response!

here is the info in brief steps:

  1. ensure thunderbird is NOT running on old machine
  2. enter %appdata% in search window on task bar and press Enter key
  3. this should open windows file explorer in Appdata\roaming folder
  4. highlight the Thunderbird folder and copy to external media
  5. ensure thunderbird is installed on second computer, started once and NOT running
  6. enter %appdata% in search window on task bar and press Enter key
  7. you should be in Appdata\roaming folder , copy&paste the exported Thunderbird folder there. This will prompt to overwrite an existing folder of same name. allow it
#   start thunderbird and all should be there 

Let me know how it goes.

IF your account is IMAP, you can reduce the size issue by deleting message folders. Let me know if that's true, and I'll give details

Not really. Never did transfer everything, but no problem. I just wanted to get it set up and I have successfully done that David. Thanks for your assist.
