If you use the commandline 7z.exe to extract the files from a wim file which contains more than one image, you must use the image number as a folder path - e.g. 1\windows\system32\wlansvc.exe. However, if the wim file contains only one image, you must extract the files using a folder path without the 1 - e.g. windows\system32\wlansvc.exe. This is inconsistent and means that an @filelist cannot be used as the filelist must either contain files beginning with 1\xxx or just xxx depending of whether the wim file has one image or multiple images!
I suggest a switch is added to force 7z to always use 1\xxx even when only one image is present in the wim file. This is a bug which affects various projects like Make_PE3 and others. The Win7 Enterprise wim file only contains one image, other Win7 wim files contain multiple images - so projects which use 7z do not work with single-image wim files!
