I suspect this is an artifact of the [Strings] original intent, which was localization. The list of files in the driver package is not expected to change from language to language, and the location of the catalog file is not expected to change from language to language. It would be an interesting experiment to manually build a .cat file that was referenced with a CatalogFile=%placeholder%.cat and see if PnP could find the .cat, which means it did the string replacement at install time. -----Original Message----- From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of Tobias Erichsen Sent: Tuesday, February 4, 2014 6:33 AM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] Inf2Cat does not use String-expansion Hello everyone, when creating an easily oem-able inf-file for customers, I noticed that the inf2cat command does not support using string-expansion %xxx% for the CatalogFile-entry and the CopyList/SourceDisksFiles-sections. Even though my inf-files show no error in ChkInf, Inf2Cat shows errors... Does anyone know if this is meant to be this way, or was this just an omission during the development of this tool?
