I'm not following you. I didn't suggest redirecting to a new file.
I suggested redirecting to the same file name you used in your
example. Further, I didn't suggest using echo--I suggested simply
this command (shown this time without the shell prompt):

> largefile

where 'largefile' is the name of the file you wish to empty.

You might find this article of help:

http://vim.wikia.com/wiki/Faster_loading_of_large_files

If you can do anything with Vim that will crash your desktop, that
would be a serious bug in Vim. Does it happen with any file over
some size? How large was your 'largefile'?
