If the SFTP server responds to a request to delete a file with the error “Permission Denied”, it means the SSH/SFTP user account does not have permission to delete the file. Here is a sample LastErrorText that shows the path of the remote file to be deleted, and the “Permission Denied” response from the server.

The LastErrorText shows the exact path of the file passed to the server.  In the case above, it is an absolute path.  If a relative path was passed, it would be relative to the HOME directory of the SSH/SFTP user account.  The “Permission denied” response from the server indicates that the FXP_REMOVE message was properly formatted and correctly sent to the server.  It was received correctly by the server, but the SSH/SFTP user account does not have permission to delete the requested file.  The fix to this problem is not on the client-side (unless a mistake in the file path was made).  The fix is on the server-side to give the SSH/SFTP user account permission to delete the requested file.
