How does FOG behave when passed an invalid file path?

[etc]

I was uploading an image to our server yesterday, but cancelled it part-way through. Afterwards I went to look on the server where we keep our images to delete any temporary files that might be left over, but I could not find the folder for that particular image. I checked the image in FOG’s web interface and realised that I had accidentally specified an invalid file path: /fogimages/backup//Backup-5-06-14 instead of /fogimages/backup/Backup-5-06-14. FOG did not warn me about this and was in fact running the upload normally before I cancelled it.
So, does FOG upload the entire image to a temporary location, then check the file path before writing to the final location? And might there be temporary files leftover from the cancelled upload in some odd location?

Thanks

check the /images/dev folder for the temp files named after the mac address of the computer they came from
