Rename files before FTP Download

[des1]

Hello...
I am trying to rename a file before it is downloaded, but I am having a brain freeze on getting this to work.  I can easily connect to the source, download all the files and log off, but I need to rename each file before it is downloaded to FileName.DateTime to eliminate overwriting an existing file in the destination folder
i.e. Files on the source are "a.txt", "b.txt", etc., I need them to be renamed to "a.txt.DateTime", "b.txt.DateTime", etc., then download them. 
Thanks,
Deryk

In order to prevent overwriting of files you can download it into buffer folder instead of destination folder. And next you can rename it and move into destination folder.

For example: you need to download a.txt, b.txt, c.txt (and others) from FTP, but you must save old versions of these files. Downloaded files stored in folder named "\destination".

See approximate algorithm below:

FTP file loop and assign each file name to FileName variable
   download {FileName} file into "\BufferFolder"
   rename \BufferFolder\{FileName} to \BufferFolder\{FileName}.{ValidFileName({DateTime})}
   move \BufferFolder\{FileName}.{ValidFileName({DateTime})} to "\destination" folder
end FTP file loop
