there is a problem in fileName[i]=FindFileData.cFileName;

this line does NOT copy the filename, it copies the pointer to the cFileName field
in your unique FindFileData struct, hence in all iterations it will point to the
buffer containing the last data written into it.

If you want to hold all the different filenames, you must copy them, which you could
do with strcpy() or strncpy().
