I use Telepathy Communication on my file transfer program. When i try to send files from HQ to shops, why sometime there will be problem occurred and i saw the files that i send to shop have extension "DBF, DB1, DB2, DB3,.....depend on how many time the same file sent again, why is it i cannot control on this. This will happened provided the previous file transfer have problem and the DBF just stay in one of the folder and subsequent file transfer will automatic increment the file extension by 1?
