INTRODUCTION
This article discusses why some files that you restore by using Disk Commander have a file size of zero or are unreadable.

Note Disk Commander is a tool in ERD Commander. ERD Commander is a component in Winternals Administrator's Pak.



MORE INFORMATION
Disk Commander tries to recover files by scanning each sector of a drive for file fragments. Disk Commander tries to reassemble these file fragments by using several speculative and heuristic algorithms. Disk Commander may write partial files because Disk Commander tries to reassemble all the file fragments that it encounters.

Even though a file appears to be successfully restored, the contents of the file may be corrupted. This issue always occurs if the file was deleted before it was restored. In this case, the file that was deleted may have been overwritten by other file data.

Therefore, we recommend that you carefully examine files that you restore by using Disk Commander to make sure that the contents of the files have not been corrupted.
