Veracrypt encrypted file - how to expand the Volume
Solution 1:
Veracrypt for Linux doesn’t have an “expand volume”. This seems to be Windows only and from some quick googling may have significant reliability issues. I would suggest making a backup before trying this. If you have the space to make a backup, it might be easier and more reliable to simply make a new bigger container and move the files across.
The Drive Letters (A-Z) are mount points for Windows. Veracrypt does not care what letter you use.
