Deleted Files

Bob,

I am using the "put" because I am writing to a ftp web server.   So I need to pass a username and password.

How would I rename the file on a remote server?  Also, how would you suggest I go about this?  I could end up in a endless error check...

rename the original file
write the data
if error then
  rename the original file back
  if error then
    then what?

What do you think?

> After reading a bit more of your original post, I think I understand that you are creating an XML file each time you do a PUT? If so, are you "PUTTING" to the same file name each time? If so, then if the command fails for some reason the file system would delete the original, and then the new file, having failed would never get to the server. It might be better to rename the original, "PUT" the new XML file, verify the existence of the file after "PUTTING" it, then delete the old one.
