8.3.5 File Names
The maximum size of the file name that can be stored, run as a program, or FTP
transferred in the CR800 is 59 characters. If the name is longer than 59 characters,
an Invalid Filename error is displayed. If several files are stored, each with a
long filename, memory allocated to the root directory can be exceeded before the
actual memory of storing files is exceeded. When this occurs, an "insufficient
resources or memory full" error is displayed.
8.3.6 File System Errors
Table File System Error Codes
