Hello David,
Since it is a design decision,there is a problem in uploading a large 
folder.
First I set maximum cached size 2048MB,then I upload a large 
folder(1.02GB),but an internal error occurred.
Here is log information:

Sometimes I do the same thing like above,another internal error occurred.
Here is log information:

To suppose that I uploaded the large folder(1.02GB) successfully, RSE FTP 
will use more time than other ftp such as cuteftp to upload a file.
So RSE FTP's efficiency of transmission is lower than other ftp.

How to deal with the internal error? How to enhance the transmission 
efficiency of RSE FTP?

Thanks ahead of time.
