Recently a virus attacked my pc and cleared 5% of my hard disk which has one partition I viewed the disk in a hex viewer program like active undelete ,cleared the virus data and overwrote it with 1s

I want to recover a large file that is about 10gb, but no recovery tools seem to be able to recover any files.

I want to know ,in theory, is this file recoverable ? I think that files are fragmented, researched about NTFS File System and i understand cluster information are just saved in MFT File ?

Is there any way to recover file without a MFT structure ?
