Overwriting files on mounted image?

[Nancy]

this is my first time ever trying to mount an image & whatnot; so please bear with me on tech talk...

I have successfully mounted and installed the desired game; I am at the last step where I have to overwrite files that have been installed on the mounted image.

However, when I attempt to copy over the files to the virtual drive, it alerts me that I need additional space.

Also I noticed that I cannot delete files in the target folder.

Is there another way to get these files overwritten? Am I having trouble because I'm using DT Lite?

Thanks in advance!

Who told you that?
