Why are you doing that? The directions are very simple.
1. Extact Uncharted 3 to your PC.
2. Copy extract.bat ,psarc.exe and zlib.net.dll from the UC3-355FiX.rar to PS3_GAME\USRDIR\BUILD\MAIN.
2. Run the extract.bat (this will extract the required psarc files and delete them when finished).
3. Rename the "bindc1" folder to "dc1" and move it inside the empty "bin" folder.
4. copy the "USRDIR" folder from the UC3-355FiX.rar into the PS3_GAME folder of Uncharted 3 (Click yes to overwrite all files).
5. Replace the EBOOT.BIN with the one included in the UC3-355FiX.rar.
6. Transfer Uncharted back to your PS3, launch in Multiman.
