Weston Pace commented on ARROW-16392:
-------------------------------------
Right now if we see {{file:///}} we drop the first 7 characters. When we get a
URI with a drive letter:
{noformat}
file:///C:/}}
{noformat}
We need to drop the first 8 characters. The easiest thing to do would be to
check if the first segment ends in a colon and assume it's a drive letter.

> letter
