This may not be a big doubt or querry but kindly have patience.
I m using fopen with nand flash memory. when is perform
FILE* file; char filepath[PROTO_FILEPATH_SIZE]; ... file = fopen(filename, "w"); //filename = "Docs\CBE renamed.txt" ...
fopen creates a file with the name 'CBD renamed' in the folder Docs (no .txt extension). for any other filename without space characters, file is created with the extension '.txt'
kindly advise
This is a little bit of text about the file name handling - actually about # of files you can store in the root directory, but it does mention a bit about processing of file names.
