Load image from device without letter...

[fatalerror]

normally a drive can have no driveletter in two cases:
1. It is mounted as a folder on another NTFS volume.
2. It is not mounted

in your screenshot you can see the file with an opendialog control, so this code should work:

Delphi-Quellcode:

if OpenDialog1.execute then
begin
    str_path:= ExpandFileName(OpenDialog1.FileName);
    ShowMessage(str_path);
end;
