[Tex/LaTex] “Cannot find file” error when running biber

biberbiblatexerrors

I'm commuting to using the new biber/biblatex system of referencing. Previously I have been using bibtex as a backend and have tried converting to biber. I'm using MikTeX 2.9 under windows xp sp3.

I compiled my thesis: project name: Thesis_1; backend=biber is set in the options for biblatex.

This runs with the expected reference and shortcut warnings.

Then I run biber Thesis_1 and get:

INFO - This is Biber 0.9.6
INFO - Logfile is 'Thesis_1.blg'
INFO - Reading 'Thesis_1.bcf'
INFO - Found 0 citekeys in bib section 0
INFO - Found 3 citekeys in bib section 1
INFO - Found 132 citekeys in bib section 0
INFO - Processing bib section 0
INFO - Looking for bibtex format file 'References/References1' for section 0
ERROR - Cannot find file 'References/References1'!
INFO - ERRORS: 1

You can see that I have my bibliography file inside a folder called References within the project folder and that the bib file is called References1.bib.

The file is there of course.

One possible cause may be a bug related to cross-platform compatibility. The file has been called References/References1, but a backslash should have been used instead for a windows path. Maybe it's not this at all, but it would be nice to have a fix.

The question was answered adaquatly, first by Ulrike Fischer and then by PLK in comments above. I'm putting this in so that the question isn't left at an open end.

The issue was that I did not have the .bib extension in the \addbibresource{} command. It was unneeded when using biblatex with bibtex, but was needed when using it with biber.
