Hi Yamini,
Thanks for contacting Syncfusion support.
We checked your reported scenario and would like to mention that currently, the required toolbar items would be shown in mobile mode to perform file operations when clicking on the specified file/folder.
Refer to the screenshot:
However, we will validate further on the mentioned scenario to show the context menu in File Manager with mobile mode. We will update you further details within three business days by September 24th, 2021.
We appreciate your patience.
Regards,
Sharon Sanchez S.
