Okay, by the software do you mean that in the BP or the transfer software. What I was doing was moving using Explorer files from one folder to another selectively and wasn't sure whether to move or leave the LASTFILE.AA. Does each folder need one, does it just exist at the end of the root, etc.? ----- Original Message ----- From: "ROB MEREDITH" <rmeredith@xxxxxxx> To: <bookport@xxxxxxxxxxxxx> Sent: Wednesday, November 03, 2004 7:53 AM Subject: [bookport] Re: Question about file structure Don't worry about lastfile._AA. The software will take care of it. >>> gwunder@xxxxxxxxxxxxx 11/03/04 08:38AM >>> Last evening I moved some files from one folder to another. It appears to have worked. I moved all three files associated with each file name, but am confused because I see a lastfile.aa. Should there be one in each folder? Gary Wunder gwunder@xxxxxxxxxxxxx=20
