That folder in the video where we did all the copying and pasting too "COD4 Mod Tools" and the X4 RAW folder could be put on an 8gb USB thumb drive
Then you can work on any computer you have access too. Only change you have to make is when you plug in the thumb drive, find out what Letter is assigned to it, and edit your makemod.cmd accordingly.
Now you can compile the mod.ff and z_x4.iwd outside of an operating system, so to speak.
((This is how I work on the mods from Home - to work - to my laptop - to where-ever))
