ESP32 S3 Sd-card FAT System long filename

Hi Ben
Creating a file automatically with Flowcode is easy. Generating a file name is also easy.
But with 8.3 digits no date and time can be used as filename.
Would it be possible in the future to work with long filenames with the Flowcode component?
I have found a setting in the ESP32 S3 setup.
somehow it should work
regards
Stefan

Hi Stefan,
That setting could work with the ESP32 specific SD mode component which uses the IDF libraries. I don't think I do anything to force it to be in the 8.3 format.
The standard SPI based SD card component will be more work to add the support for. It's something I've wanted to add for a long time but never managed to get around to.

Hi Ben
This is a great advantage for my recorder.
It's working nice, Flowcode, File_ESP32_SDMode1 and longfile name.

Even if I don't know what heap or stack means. Both settings work fine

Excellent that's good to know thanks.
As per the Stack/Heap setting I found this info. Both are in RAM but it's probably the top vs bottom of memory. Probably stack is the better option.
The stack is generally used for storing small, short-lived variables such as local variables and function parameters, while the heap is generally used for storing larger, longer-lived objects.
