Section 8. Operation 8.3.4.4 File Management Q & A Q: How do I hide a program file on the CR1000 without using the CRBasic FileManage() instruction? 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 CR1000 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. 347) 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 82. File System Error Codes Error Code Description 1 Invalid format 2 Device capabilities error 3 Unable to allocate memory for file operation 4 Max number of available files exceeded 5 No file entry exists in directory 6 Disk change occurred 7 Part of the path (subdirectory) was not found 8 File at EOF 9 Bad cluster encountered 10 No file buffer available 11 Filename too long or has bad chars 12 File in path is not a directory 13 Access permission, opening DIR or LABEL as file, or trying to open file as DIR or mkdir existing file 14 Opening read-only file for write 15 Disk full (can't allocate new cluster) 16 Root directory is full 17 Bad file ptr (pointer) or device not initialized 18 Device does not support this operation 347

8.3.4.4 File Management Q & A
Q: How do I hide a program file on the CR1000 without using the CRBasic
FileManage()
instruction?
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 CR1000 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. 347)
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.
