How to create and manage the file allocation table
The file file_db.txt is located in the file system of your Advanced CP in the folder /config. You
can upload the file as originally shipped with your CP to your PG/PC and use it as a template
for your application. You will also find the sample text in the properties dialog of the CP in the
"FTP" tab.
You can manage this file with the normal FTP commands as described in Section 10.2 for
the IT file system.
If the file file_db.txt does not exist, it is not possible to access file DBs using the FTP server
of the Advanced CP. After editing the file and transferring it to the file system of the
Advanced CP, you should therefore make sure that the transfer was successful.
If both the transfer and syntax were correct, the following message is displayed:
"226 Transfer ok; closing data connection"
If the syntax is incorrect, a message similar to the one shown below will be displayed:
"450 Requested action aborted - configuration file error in line 16"
If an error was reported, check your system configuration and repeat the transfer. You can
check your configuration with the following command:
ftp> dir cpux (where x = 1-4)
Note
Note the use of lower-case letters. Otherwise the files will not be recognized.
