Delete client avatar via ServerQuery

Hello,

is it possible to delete the client avatars via ServerQuery?
When I try to delete an avatar file, I will get an error.
This
ftdeletefile cid=0 cpw="" name=/avatar_jalmddbgndhabnhjmilabiljepnhnjicadkidlfj
results with
error id=1540 msg=convert\serror

Files in other channels can be deleted without a problem.
Does someone has the same problem?
I am using the TeamSpeak server version 3.12.1.

You can not set or remove client avatars via Query.
This must be done in the client itself. Thats the only supported way.

Ah okay. Thank you for the information.

Hi you can delete an avatar with YaTQA
