I have a file on this path:
`~/Downloads/flightlog_2017-71-19_19747.txt`

But when i try to write or check if it exist:

`fs.existsSync('~/Downloads/flightlog_2017-71-19_19747.txt')`

It always return `false`

If I do in terminal:

`$ nano ~/Downloads/flightlog_2017-71-19_19747.txt`

This works fine
