I am not sure why you can't get a full list? Have you tried using different ftp software? Also, as a side note, in many cases using an account like you described is associated with keylogging. Keylogging and any kind of similar activity is extremely illegal and violates our Terms of Service (TOS). Having such an account results in an immediate account termination, ip ban, and the forwarding of all logs to the proper authorities.

Okay, as long as you don't know what it is it's fine.. in many cases, the need to upload many files like that is for key logging. In any case, how many files you can see would depend on your FTP program, FTP program settings, and computer settings. I am not aware of anything on the server that would be causing this limit. You might want to try searching on google for programs designed specifically to see all the files.
