Ok, I see.

You need to set the config _USE_FIND to 1 in ffconf.h to use that function.

You can find the file ffconf.h in the folder SDK_folder\external\fatfs\src

USB is not connected when i am trying to use that function. it should not be connected as I am trying to locate the next file on the drive and open it for reading.

Hi,

Is the nRF USB connected ?

As mentioned in the example description:

"This example allows you to manipulate the file system (on QSPI memory) only while USB is not connected. If USB is connected, access to the file system from a user application is not possible because MSC is not designed to allow access to the file system from multiple sources. To disable FatFS capabilities, set USE_FATFS_QSPI to 0."
