Hi,

You have just to change the value of_USE_LFN deifine that switches the LFN feature.

#define _USE_LFN 0 /* 0 to 3 */
/* The _USE_LFN option switches the LFN feature.
/
/ 0: Disable LFN feature. _MAX_LFN has no effect.
/ 1: Enable LFN with static working buffer on the BSS. Always NOT reentrant.
/ 2: Enable LFN with dynamic working buffer on the STACK.
/ 3: Enable LFN with dynamic working buffer on the HEAP.

This define is available under the FatFs configuration file: ffconf.h With regards.
