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 rformat value specifies the file format an application can read (convert from).
The rwformat value specifies the file format an application can read and write (activate as).
