I am trying to upload 2 accessories. However, when I do so, Content Uploader complains with the following error:

 
As you can see the file name of the accessory meets the naming requirements and I even tried renaming it to ensure the the spaces were ordinary spaces. However, I have managed to upload CC Accessories in the past.

Is there a way to somehow determine, more specifically, what the problem is? The content was created in CC 2.11.

When I tried to upload the CC ccAcc files for the content, Content Uploader would not accept them.
When I pushed the character to iClone 7 and then saved the accessories in iClone 7 (also as iAcc files), I was able to upload the content.

EDIT: CC uses ccAcc while iClone 7 uses iAcc files.

Thanks for reporting. Developers can upload ccAcc files now

Confirmed. Uploading ccAcc file seem to work now. Thanks.
