actually i was sucked by the long queue of downloaded files in my mozilla firefox idm extension that was installed from the microsoft app store. i tried to delete all the list but instead i deleted the actual files somehow. it was a huge mistake made by me. By looking deep i see that there were two options to either delete the file names or delete the actual file from its location, i misinterpreted the signs and press the icon for removal of files instead of file names from the list. please help me to recover my data.
