Peter - Take a look at the contents of the CF card using your PC CF reader/burner after you've moved a .txt file, for example, using the BP interface and note the file names and extensions. Yes, BP Transfer does massage the files. I have absolutely no problem with this aspect of things, given that the transfer is fast and in my case, at least, it really doesn't make a dime's worth of difference whether I'm transferring from the desktop to the BP or to a CF card. ----- Original Message ----- From: "Peter Rand" <peter.rand@xxxxxxxxxxxx> To: <bookport@xxxxxxxxxxxxx> Sent: Tuesday, August 17, 2004 4:14 PM Subject: [bookport] Re: Unfiltered files error Rob wrote: --- Book Port does not support files which were not sent through Book Port = Transfer ....=20 --- Just out of curiosity, is there a technical reason for this?
