[digiKam-users] Second copy of Digikam on Windows 7 PC possible?

[Shel Ritter]

Thanks for the input Gilles. Looking into the \AppData configuration 
folder, it seemed like the config file would have been: yolov3-face.cfg

  Volume in drive C:

  Directory of C:\Users\<user>\AppData\Roaming\digikam\facesengine

10:34 PM    <DIR>          .
10:34 PM    <DIR>          ..
08:16 PM            28,092 deploy.prototxt
10:34 PM                 0 dir.txt
08:16 PM        31,510,785 openface_nn4.small2.v1.t7
08:16 PM         5,351,047 res10_300x300_ssd_iter_140000_fp16.caffemodel
08:16 PM        67,740,572 shapepredictor.dat
08:16 PM             8,334 yolov3-face.cfg
08:26 PM       246,305,388 yolov3-wider_16000.weights
    7 File(s)    350,944,218 bytes

So I ran this, expecting to see my current installation boot:

digikam.exe --config 
C:\Users\<user>\AppData\Roaming\digikam\facesengine\yolov3-face.cfg

Instead DigiKam opened as if it was opening for the 1st time. It just 
wasn't recognizing yolov3-face.cfg as a valid config file, and opened as 
a fresh installation no matter what file I pointed it to. That initial 
window that pops up refers to, "The new location for configuration files 
is ~/Local Settings/ ~(old AppData/Local/). But the only Digikam files 
there are 2 simple text files in the root AppData/Local/ folder,  
digikam_systemrc 45 KB and digikamrc 88KB that the --config command ignores.

I can't see any other locations where a valid config file might be. And 
if the --help output for --database-directory <dir> is referring to a 
folder that should literally be named dir somewhere, I couldn't find it.

Admittedly I'm not great at the technical end of things. 😉
