I know that this question has been asked before on this site, but I am very new with Cygwin and am really confused by a lot of the other answers.
What is the best method to change my home directory in Cygwin?
Perhaps the most easier way is to make a folder junction with mklink.exe
windows command. Assuming that you would like to use windows home directory:
cmd
. c:\cygwin\home\username --> username_backup
mklink /j c:\cygwin\home\username c:\Users\username
