Peace upon you ....
I'm using Thunderbird from many years ago, I've conveyed whole my data form standard TB to Portable TB (from 1 year ago), but the size of my data became so big (2,3 GB), so it's too difficult to put whole data on my USB stick .
My question :
I need to make archive file for my old data to keep them on my hard-disk and ship the other data on my USB stick ?
1- I've put in my data sub-folders and Message filters
2- sorry for my stupid question, but i think the solving of this problem can do here.
