I'm a newbie running DOSBox 0.74 and I'm tryng to install Contructor.

I have mount a local directory D:\Games\ with the command

mount d d:\games\

Then I mount the cd drive

mount e e:\
e:\ -t cdrom

then in E:\

INSTALL

And the program works I can install the game but when I enter the destination drive :

D:\ACCLAIM\CN

It says : "Not enough disk space on the destination drive for installation" but I have 245 Go of free space on this drive
Any ideas ?
