Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Ok

when you copy files onto an SD card using a Mac there is a resource file created for every file, it is hidden and has the same file name as the original file with ._ prefixed

eg. Program.bas also has ._Program.bas

this hidden file contains thumbnails etc and other attributes.

However that said, this does not impact anything on the CMM2.

The FILES and LIST FILES command work perfectly and ignore the hidden files

if you use the following

f$ = DIR$("*.*", FILE)
DO WHILE f$ <> ""
PRINT f$
f$ = DIR$()
LOOP

You will see Program.bas and ._Program.bas

you can ignore the files

f$ = DIR$("*.*", FILE)
DO WHILE f$ <> ""
IF LEFT$(f$,2)<>"._" THEN
PRINT f$
ENDIF
f$ = DIR$()
LOOP

if it really became an issue then you could remove then

f$ = DIR$("*.*", FILE)
DO WHILE f$ <> ""
IF LEFT$(f$,2)<>"._" THEN
PRINT f$
ELSE
KILL f$
ENDIF
f$ = DIR$()
LOOP

Otherwise I can't see it as an issue really, the same thing happens with the recycle bins stored on the SD cards, they are in hidden directories and unless you really want to do something with them, just ignore them

regards

David
