iCloud recurring Upload Pending file

For the last few months I have had this 1 file in DT2go that for some reason is not able to upload.
so I get a error message on each sync.

I would like to find and resolve this, either by deleting or manually moving file but I can not find a way to find the file.
I have gone through the smart groups available and do not think are relevant.

Any ideas on how to find the file that is causing this error message ?

it is more annoying than anything else does not effect. the running of DT2go but would like to get rid of as that little triangle in the cloud is really bugging me

any ideas
thanks for help
