Download issue with attachment > 2GB

Hello,

I'm facing an issue with an attachment sized about 4GB. The file is well uploaded with the right size but when uploading it displays 2GB on the download windows and also after download.

I checked the XWiki attachment settigns but I didn't find any limitation on download parameter wich can be modified.

The attachment is configured with filesystem store base.

I need help to resolve this issue

Thanks in advance for your support

Environment :

CentOS Linux release 7.7.1908 (Core)
XWiki 10.11.9 & 11.8.1
