Yes, I want just combine files as simple as that:
File1.txt
line1
line2
line3
File2.txt
line4
line5
line6
I want to open the above two files at once and receive File3.txt in a new tab like this
line1
line2
line3
line4
line5
line6
It's odd that Sublime cannot do such simple operation. I found only this old 10yo question which is for Sublime2 so useless.
Can't Sublime 4 do this?
