Section 8. Operation Power-up.ini Execution After powerup.ini is processed, the following rules determine what CR6 program to run: • If the run-now program is changed, then it is the program that runs. • If no change is made to run-now program, but run-on-power-up program is changed, the new run-on-power-up program runs. • If neither run-on-power-up nor run-now programs are changed, the previous run-on-power-up program runs. 8.3.3.5 File Management Q & A Q: How do I hide a program file on the CR6 without using the CRBasic FileManage() instruction? A: Use the CoraScript (p. 492) File-Control command, or the web API (p. 418) FileControl command. 8.3.4 File Names The maximum size of the file name that can be stored, run as a program, or FTP transferred in the CR6 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. 8.3.5 File System Errors Table File System Error Codes (p. 391) lists error codes associated with the CR6 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 101.

Section 8.
Operation
Power-up.ini Execution
After
powerup.ini
is processed, the following rules determine what CR6 program
to run:
If the run-now program is changed, then it is the program that runs.
If no change is made to run-now program, but run-on-power-up program is
changed, the new run-on-power-up program runs.
If neither run-on-power-up nor run-now programs are changed, the previous
run-on-power-up program runs.
8.3.3.5 File Management Q & A
Q: How do I hide a program file on the CR6 without using the CRBasic
FileManage()
instruction?
A: Use the
CoraScript
(p. 492)
File-Control
command, or the
web API
(p. 418)
FileControl
command.
8.3.4
File Names
The maximum size of the file name that can be stored, run as a program, or FTP
transferred in the CR6 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.
8.3.5
File System Errors
Table
File System Error Codes
(p. 391)
lists error codes associated with the CR6 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.
