Hello Alug
I recently raised a query about archiving/exporting complete folders of emails from Thunderbird to a separate drive on my computer. Several people replied - thanks to all.
In particular 'James' said he copies emails like this all the time using the import/export add-on.
I had trouble getting the add-on to install when I tried it before, so closed down Zone Alarm & Avast while I tried to install it. I then received some info on how to install an alternative (SmartSave) and saw through this that I should be using the Tools/Add-ons menu which I wasn't familiar with. It's now installed and working fine, but I'd appreciate comments about ZA & Avast possibly being involved; and also any comments on SmartSave v Import/Export 1.6.1.
Thanks ac
