Not finding files on SD card?

Not sure why I waited so long but I just tried to load a file from an SD card (the 4 GB that came with the kit) but I am not having any luck finding the file via the LCD.
My kit only came with one set of cables so I'm assuming they are the right ones as I see in other post that it came with 2 sets of wires prior and I am using the repitier firmware.

The steps I have tried so far = format the SD card (fat and fat 32)
Slice in Repitier host with slicer and save the G-code = both .gco from save job with and without binary and as .gcode directly from the g-code editor tab
Go to LCD..... SD Card --> Mount Card.... beep --> SD Card --> Print File

There is no file listed to print??? The file's can be seen on the computer but not by the LCD screen

Any suggestions?

Files must be saved in the 8.3 naming format or you will not see them listed on the LCD control. So, for example: "bracket holder.gcode" must be renamed to something like brkthldr.gco or brack.g to be able to read it.

Back to the good old days of MS-DOS...

There is a branch of Marlin that supports long file names, the issue is the shear quantity of code required to support the SD Card, there is already probably more code in that support than the rest of the firmware combined.
The bigger issue you'll find with the SDCard support is a hardware restriction, it only supports SDCards that have an SPI interface and not all do, and it's virtually impossible to get a list of working cards.
