A: Use the CoraScript File-Control command, or the Web API FileControl command. 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 CR3000 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 (p. 352) lists error codes associated with the datalogger file system. Errors can occur when attempting to access files on any of the available drives. All occurrences are rare, but they are most likely to occur when using the CRD: drive. Table 85.
