Description
When trying to save a layer, I get error number 3 in the case of the following example:QgsVectorFileWriter.writeAsVectorFormat(layer, "C:\\Users\\Myname\\Desktop\\test1\\test2\\vectorlayer.shp", "utf-8", None, "ESRI Shapefile") would NOT work, while QgsVectorFileWriter.writeAsVectorFormat(layer, "C:\\Users\\Myname\\desktop\\Test1\\Test2\\vectorlayer.shp", "utf-8", None, "ESRI Shapefile") does work (focus on the upper/lower case of the filepath)!
There seems to be case sensitivity after my folder "desktop"..lower case of "desktop" itself does not matter but if any of the folders after desktop is lower case, I get without exception the error number 3 from QgsVectorFileWriter::WriterError

Platform used while detecting this bug was Windows 7. I don't know know about Linux, where case sensitivity of paths is native!

Use one of the following filenames to avoid Python escape sequence conversion of \\t to TAB in your filename:
"C:\\\\Users\\\\Myname\\\\Desktop\\\\test1\\\\test2\\\\vectorlayer.shp"
"C:/Users/Myname/Desktop/test1/test2/vectorlayer.shp"
Does that fix your problem?

I could reproduce using the OP's setup. And for me, using either one of your solutions fixes it.
Too bad Microsoft chose the wrong slash as their directory separator :-(
>>> QgsVectorFileWriter.writeAsVectorFormat(layer, "C:\\Users\\Myname\\Desktop\\test\\vectorlayer.shp", "utf-8", None, "ESRI Shapefile") 3 >>> QgsVectorFileWriter.writeAsVectorFormat(layer, "C:\\Users\\Myname\\Desktop\\Test\\Vectorlayer.shp", "utf-8", None, "ESRI Shapefile") 0 QgsVectorFileWriter.writeAsVectorFormat(layer, "C:\\Users\\Myname\\Desktop\\\\test\\Vectorlayer.shp", "utf-8", None, "ESRI Shapefile") 0 QgsVectorFileWriter.writeAsVectorFormat(layer, "C:\\Users\\Myname\\Desktop/test\\Vectorlayer.shp", "utf-8", None, "ESRI Shapefile") 0
And yes, one should escape every \\, not just the one causing problems. I plead guilty of laziness :-)
