WS_FTP - Error: 550 permission denied

Question/Problem: I keep receiving an error message: "550 permission denied or 550 access denied". What does this mean?

Answer/Solution: The 550 error is a message from the server stating that the account you have currently logged in as does not have permission to perform the action you are attempting. You may be trying to upload to the wrong directory or trying to delete a file.

Here is an example of when someone would receive this message:

John logs into ftp.ipswitch.com and goes to the directory /Ipswitch/Product_Downloads
In this directory John sees a list of files for users to download. If John selects a file from his local system and tries to upload it to this directory he will receive the 550 permission denied message because he does not have rights to upload to this directory. John has read and list permissions only. In order to upload John needs write permission. He could contact the system administrator to ask for write permission on the server.

The text of the error message from the server, which you can see in WS_FTP's transfer log, may tell you more about the problem.

This problem can also be caused by a firewall with a "no ftp write" permission set.
