Info.plist, Manifest.mbdb, Manifest.plist, Status.plist files are missing in backup folder

I restored my iphone 5 to the default setting.

Before restoring, I backed up the data in iphone but backup files have been corrupted.

I found that Info.plist, Manifest.mbdb, Manifest.plist, Status.plist files are missing in the folder where the back up files are located.

(C:\user\user name\AppData\Roaming\Apple Computer\MobileSync\Backup)

I copied these files from another backup in the folder of the corrupted backup, but it did not work on either itunes or third party software.

I even opened each of 4 files and modified the date, but still does not work.

I know I can change extension of each file in the corrupted backup folder, but there are more than 8000 files in that folder.

Is there any way to create the 4 files for the corrupted backup file?
