[BUG] M23 for file in folder give "open failed" error

[fgiudice98]

As per title the M23 command (from pronterface, octoprint and others) for file in folder give "open failed" error, so cannot start a print from a file in a folder. I tried with different filenames for folders but without luck. The files work good when printing from lcd.

Below the pronterface console output

>>> M23 /TEST/PRINT_~1.GCO
SENDING:M23 /TEST/PRINT_~1.GCO
echo:Now fresh file: /TEST/PRINT_~1.GCO
open failed, File: PRINT_~1.GCO.

I am running the latest firmware on full stock Mega-S.

Another thing, is it possible to enable M33 command?

Thank in advance
