Unable to delete files and collaborative spaces

Hello,

I am new to 3DExperience cloud.

 

Problem 1 :

A file that I am not the author of and on which I nevertheless appear as the owner, has been embedded in one of my collaborative spaces. I cannot delete this file even if I identify myself as Administrator! A notification tells me that I do not have the appropriate access rights...

 

Problem 2 :

I also cannot delete a collaborative space that I created myself, telling me

"Deletion failed

The remaining data prevents the deletion of this collaborative space

3 objects can be moved to their parent collaborative space of control..."

Except that there is nothing in it!!!

 

I have tried a multitude of things in vain... I am leaving it to you!!!

How should I go about it? Thank you in advance for your help
