Removing Old Files (Import Manager)

Hello,
I removed 2 big 130kb~ files from my map, and they exist anyway
Before, the map was like 509kb big, but now it is 509kb after i removed those big files.

Why is it like that and how can i remove them completely?

I don't know if this would help, but you could use some mpq software.

it doesnt work :(

That's happened to me before, but that was with WC3 vanilla, and I thought it was fixed in a patch ages ago.

I know this would be hard work but you could make a new map and copy everything except of the old files into it?

do i have to change all the data that i have changed in my map or is it a way to copy all the changed data?
