System files generally have two formats: ISO format and GHO format. ISO format is divided into original system Ghost packaging system two kinds. As long as the decompression software winrar decompression is greater than 600M (WIN7 general 2G) above the Gho file, is Ghost Packaging system, PE in the speed of the smart installed PE version software can directly support the restore installation. If decompression after no more than 600M Gho file is the original ISO format system, to install the orig
