Once I’ve lost Icon data stored in Resource Fork saving to NTFS, can those files be repaired? How can I repair the Icon in Resource Fork from a folder copied to a NTFS disk?

I recently backed up my dying SSD onto a NTFS drive using an older Snow Leopard Machine and almost all my data was saved. But all the folders lost their associated icons in this process. Some icon creators distribute their work in this way, assigning icons to folders and no contents in them.

I still have a file inside each folder named "Icon?" or "IconˆM" (when using the tab to complete its name in the terminal). This file is 0 bytes in size every time.

Is it possible to recover all these icons from all these folders containing the "Icon?" file?
Repairing would mean you have a backup of the data that was lost. The resource data is gone if the size of the file is 0 bytes.

Look for backup copies of the apps or installers / download the apps / folders icons from a file system where that data was encoded correctly or support data and resource forks natively.
