Strange [trash] folder after word document manipulation

Hi,
I used aspose word for java (24.4 version) to modify the document 050 - Debt Capacity.docx (attached) adding some custom xml and removing/adding properties to the document.
If I unzip the resulting document 050 - Debt Capacity_modified.docx (attached) I found a folder named [trash]. Why? What does it contain? Is It possible to remove It?

Thanks in advance.

@ernestocastellano Could you please provide a simple code example that will allow us to reproduce the problem? We will check the issue and provide you more information.

I noticed that the folder has been created after the file has been uploaded on Sharepoint.

Sorry!
