How to get root folder of SD card?

Hi,

reyalp told me (thanks):

You can read and write files using stdio functions like fopen etc. You can list directories using opendir/readdir (look at the file browser code for examples)

Before diving into the file browser code I have to questions:

1. How do I get the root folder of the SD card?

2. Is it possible to write some simple txt-file using CHDK into the root folder (or any other directory) of the SD card?

Thanks!

The root of the filesystem is A/

Note the / is part of the name. For any other directory, you should not put a / at the end.

Yes. Just use, fopen, fwrite and fclose like you would on any other OS.

Don't forget what the H stands for.
