Im working with Texmaker and use the option „use a „build“ in subdirectory“ to get a tidy folder.
My problem was to parse the relative path to biber. So i got an error of:
ERROR - Cannot find control file 'example.bcf'! - did you pass the "backend=biber" option to BibLaTeX? INFO - ERRORS: 1
The solution is to change the settings of Texmaker in the field of „Bib(La)Tex“ to
"C:/Program Files/MiKTeX 2.9/miktex/bin/x64/biber.exe" build%
