Read/Write Permissions on folders?

I have a client who wants to put some files on my server, but she said she cannot because it tells her she doesn't have permission to do that. Does anyone know how I would fix this? Read/write permission on the folder? Doesn't seem to be a way.

Thanks.

Anyone???

this is most likely a ftp server configuration issue, so you came to the wrong place (you didn't even tell us which ftp server you're using, so how can you expect anyone to be able to help you?). smartftp is just an ftp client.
