Hello Frank,

The FAT component in v4 had issues due to an issue converting bytes to longs and visa versa which means that at a file size of 16K there were issues.

We have fully fixed this issue in v5 of Flowcode so upgrading to this could be one option for you.

The other option is to customise the FAT16 component C file using code customisation or by editing the C file to give you the more reliable functionality.

Let me know what you want to do and I will help where I can.

Thanks for answers
I just upgrade to v5, I would do it anyway, so it's ok.
