Issue File Extension is file Size

I am currently experiencing the file size being added to the file extension when transfering information from Command Line Client to a UNIX server. Does anyone know why this is happening and how do I stop the file size being added to the file extension.

Example: football.pqt.11108
football.pqt is the corect way and how I wont the file to be transfered. How do I remove the .11108 which is the same as the file size?

I am wondering why this is doing in "IP Networking". Anyway

From what OS with which command line client are you transfering? ftp? scp? ...?
This doesn't look like a default function of a Linux or Unix ftp client or scp etc.

Basically you can get rid of the suffix by issuing something like:

$> echo football.pqt.11108| sed 's/\.[^\.]*$//'
football.pqt

Put it together with a mv command, maybe in a while/read loop.
