OLE stored in Oracle -- save as native file

Hi all PB gurus,

I just tried my luck to see if it is possible to convert any OLE objects saved in Oracle BLOG via PB OLE controls back into their native file?  We need to generalize the ole-BLOB back to the native file in another BLOB/CLOB column so that any non-PowerBuilder application can also use the stored file

I initially thought it will be just as simple as trimming certain bytes in the BLOB for a given file extension but apparently the data looks very different when comparing the native file vs the saved blob.

Thanks very much!
