This came up in Quotes hell but is perhaps worthy of its own thread.

Precisely as the subject line says, typing

1mount c c:"

in DOSBox works for some reason, and produces the message

1Drive C is mounted as local directory C:"\

It's unclear exactly what DOSBox ends up mounting in this case; the resulting C drive appears to have no files on it.

Granted, there's very little reason someone would purposefully type the command in question, but perhaps it is indicative of some potentially greater problem.
