4.6Installing Files
During the installing-files stage of driver installation, SetupAPI logs messages that are associated with a DIF_INSTALLDEVICEFILES request. The installers process the CopyFiles, DelFiles, and RenFiles directives from an INF file to generate a list of the files to copy, delete, and rename. SetupAPI adds device files, co-installer files, and interface files to the file queue. (In general, SetupAPI copies files before any irreversible installation actions occur.)The following example illustrates what the subsection that is associated with this stage looks like for an Oven device, if the default logging level is set.
#-166 Device install function: DIF_INSTALLDEVICEFILES.
#-124 Doing copy-only install of "Oven_Device_Instance_ID_2".
In the previous example, the #-166 message indicates that SetupAPI initiated the processing of the DIF_INSTALLDEVICEFILES request for the device, while the #-124 message indicates that SetupAPI is doing a copy-only installation for the device.
