FTP permission denied error

I am trying to FTP a RAR (zipped) file to another server but am having problems doing so. This is a Windows environment. I know that my FTP connection is setup correctly because I have already transferred over several other RARs. But the difference from what I can tell is that this RAR that is failing is larger in size. It is 761 MB. So when I try to "put" it into the other server, I get the following:

200 PORT command successful.
150 Opening BINARY m开发者_如何学Code data connection for WCU.rar.
> WCU.rar:Permission denied
226 Transfer complete.

However, the file is never transferred over. Is there a size limitation? And FYI, WCU.rar is a zipped directory, not a file. But I was able to successfully FTP over several other zipped directories.

it can be size limitation, not just stored data but as well transfered data.
did you try to transfer a small file? a small file in the same format? I would say, permissions, but you said that you uploaded already files to this server.

just to help you debug, you can add both commands to your ftp session

ftp> hash
ftp> bin

WCU.rar:Permission denied

You don't have permission to write to that directory. You need write permissions on the folder in order to do so.
