File and folder names viewed from an FTP client are prefixed with the date and time.
This behavior may occur with files or folders whose owner contains a space character. Some graphical base FTP clients mis-interpret the space character as the separator between the owner and the group. When this occurs, the client shifts the date and time fields and assumes them as the prefix for the filename. As a result, many common FTP functions will fail.
To workaround such issue, one may use a client capable of recognizing the presence of the space character in the owner of files/folders.
Another alternative would be to switch to a username scheme where the space character is not used. Note the ownership of files must be taken by a user without a space if this option is chosen. For help on managing file/folders permissions, see the Share and File Access section of the built-in help or the admin guide.
