Conversion information is used by the Convert dialog box to determine what formats an application can read and write. A comma-delimited file format is indicated by a number if it is one of the Clipboard formats defined in WINDOWS.H. A string indicates the format is not one defined in WINDOWS.H (private). In this case, the readable and writable format is CF_OUTLINE (private).
The following is a \Readable entry:
KEY_CLASSES_ROOT\CLSID\{00000402-0000-0000-C000-000000000046}
\Conversion\Readable\Main = Outline,1
The following is a \ReadWritable entry:
HKEY_CLASSES_ROOT\CLSID\{00000402-0000-0000-C000-000000000046}
\Conversion\Readwritable\Main = Outline,1
