BspZipGui

BspZipGui is a GUI (graphical) tool for Valve's BSPZIP command line tool. It is easy to use. Just paste a folder with files (textures, models, scripts, etc) into the BSP file. With the program you can also extract all the files contained inside the BSP file. The main feature of BspZipGui is that it automatically generates a list of files from the folder you specify and then runs bspzip.exe to insert these files into the BSP. The application can be used for any game, including Nuclear Dawn, Left 4 Dead 2 and Counter Strike Global Offensive.
