Can not transfer mp3 file by FTP correctly

[RiseFly]

When i'm syncing a MP3 file from a pc to a FTP location, then the size increase and the file gets corrupt on the FTP. So there is no way i can use the MP3 on the FTP location anymore.
How can i solve this ?

Please confirm if you have set the transfer mode to "Binary Mode" when transferring the .mp3 file.
Here are the steps.
1. In the FTP folder browser, click the "Advanced..." button
2. In the "FTP Advanced Setting" dialog box, click "Transfer Mode" TAB.
Use "Binary Mode" or "Switch mode by file type" option.
When use "Switch mode by file type" option, please ensure that ".mp3" is not in the "Send the following file types by ASCII mode" edit box

Or May be the FTP server has something wrong, just install/use another FTP server.
