On JioCloud, choose a file or folder which you want to unshare. Click on 'Share' icon -> 'Manage share'. Now remove all the private share users that you have added. You need to click on the list below Manage access, tap on the permissions given and select remove. Besides, at the bottom, you need to make the public link (below the Get link heading) as restricted, if the current permission has been set as Anyone with the link can view/edit. Once the changes are done, hit the Save/Done button.
