CSF

ra2.csf is the string file of RA2 (ra2md.csf for YR), in which all on-screen text is saved. It is edited either with the XCC String Table Editor (by Olaf van der Spek) or with RA2StrEdit (by TheMatze).

In XCC Mixer go to Launch --> XCC String Table Editor --> Red Alert 2 or Red Alert 2 YR, whether you are modding RA2 or YR. XCC String Table Editor is used to modify the ra2.csf and ra2md.csf files. First in the left column click on whichever stringtype you want to add, usually this is "NAME" because that controls the names of all units, superweapons, and buildings next click on "insert", then making sure that the string you just created is still selected, click on "edit" and in the big text box in the middle of the window that pops-up add whatever text you want displayed in game. Don't mess with the bottom text box, as far as I know it is unused. Apparently if you switch string type sections before saving, then it will delete all changes to the strings in that section. XCC String Editor only edits the RA2.CSF and RA2MD.CSF files that are in the directory in which you most recently installed RA2/YR.
