Retrieve config files from TXX phones

[lacava]

Thanks for your reply.
Sorry I was not too much clear.
When I said config files, I said all .cfg files such as "local_config" and "all_config".
When I click on 'Export' button in Settings -> Configuration in section : Export CFG Configuration File, it ask me to download a file with name : "IDnumber-local.cfg" for a local config. I'm asking, how this file is generated first, to retrieve it with script. And I want to know where this file is stored to retrieve if it's possible. I'll do a script by myself but I just need to know where this file is.
Thanks.
