Dear xaizek, it's only script issues. We are near of solution. With the last test I achieved al least launch the file in other cmd session, the only point that I want to solve is what I'll describe for you.
Now, with this statement...
filetype *.txt cmd && start "C:\Program Files (x86)\Vim\vim82\vim.exe"
Occurs the following...
I press Enter over file >> CMD is opened >> I close the CMD >> The file in VIM pop up
WE ARE REALLY CLOSER, only remains that wont be neccessary to close CMD for view the txt file.
