Backup problems with PC companion

[H4rry]

I am trying to backup my xperia z1 with PC companion but it keeps failing the problem is with the photos file as when I don't tick the photos box everything else backs up fine.

Is there any other way to backup my photos onto my PC? 

[KeepTrying]

I have opened up File Manager from within Sony PC Companion and none of my data is there.

Specifically I cannot find my photos and videos so that I can manually transfer them to my PC.

Any suggestions, please?
