[CzechTexan]

Unzip the file to a temporary folder. I usually unzip my zip files to a folder in Myfiles named Downloads or Unzipped.
When you unzip, you will see some files that you will need to manually copy/paste into your cztx_Burmalower map folder that you already have. These new files will replace the old ones.
Here is the directions from the README file that is included with this PATCH download:

Installation Instructions:

1. A new village texture by fabianfred named fsk_country_mount is in the "land" folder. Put "fsk_country_mount" in this sequence: MODS/MAPMODS/MAPS/_TEX/land/summer/...

2. Place the new "load" file into your BurmaLower map folder if you are using the new texture mentioned above. Delete the old load.ini file. Sequence: MODS/MAPMODS/MAPS/cztx_BurmaLower/...

3. Place the new Map_C, map_c.tga_table, map_T, and actors.static into your BurmaLower map folder. Delete the old ones.
Sequence: MODS/MAPMODS/MAPS/cztx_BurmaLower/...


Notes:
*The new village texture, map_C, and map_c.tga_table were made by fabianfred. This helps the villages look better in the surrounding environment and also adds more river area in the eastern part of the map like the Salween River.
*Map_T changes the textures mainly in the southern region so that the rice paddies and fields are not so repetitive. The fields are broken up by using the "fsk_midland4" texture.
*the new Actors.static file has reworked Thailand airfields with longer runways and a few other minor things on the map.

Misha, let me know if you need any further help.
