As a non-computer expert, it took me longer to understand the process. But once you understand it, it's brilliantly simple:

Here my example:

The following files are in one folder ...\pdflink\
* easy_living-C-stimme.pdf
* easy_living.mscz
* easy_living.musicxml (only if a link to Android software "Practice Bird" is needed)

(pdf-, mscz- and musicxml-file might have the same name)

* PDFLink.exe (from the github-link above)
* plink.bat

The batch plink.bat contains the following lines (2. line only for "Practice Bird"):
pdflink.exe --iconsize=40 --xpos=10 --ypos=10 --verbose --gfunder --padding=3 --targets=%1.mscz %2.pdf
pdflink.exe --iconsize=40 --xpos=500 --ypos=10 --verbose --gfunder --padding=3 --targets=%1.musicxml %2.pdf

Start the batch using the cmd-input at ...\PDFLink\plink mscz-file pdf-file
Example: plink easy_living easy_living-c-stimme

It takes about 10 seconds to get the link(s) added to the pdf.

After that you can add the pdf to mobilesheets as usual.
After that you need to add the mscz- (and for Android the musicxml-files) to the same folder as the pdf-file.

Thats's all!
Thank you very much to sciurius and itsme!
