To: A. Trivedi - thank you for the reply but I am still lost. I presume you mean a "memory stick that fits into my USB port" when you mention "USB flash drive"? My memory stick has no "archive.pst file" on it - at least Outlook can't find one. When I try to open the archive file on my hard drive (it is 1.99 GB in size) I get a message that it is full and Outlook won't open it. I have no idea what is in it. For some mysterious reason it won't take any new data and won't open so I can throw stuff out. Thus I am still blocked.
