I have files which are backed up, have been compressed some dating 1998, whether created in MS Word or Adobe and some will open properly in Word, Excel or Adobe. Those that do not open properly error message Not Supported File Type, however it is a PDF or DOC formated however MS Word will open and all I see is 5= 6ˆ I attached the file Any suggestions on how resolve this issue? Thank you, Doc faxKay_Jewelers.doc
