As above, the SD Card view file default hides many file types including .macro, which is the primary reason I got the SD card reader and spent a few hours trying to get it working when it was working, just not showing any files (which happened to be all .macro files for the QuickChangeATC setup). Can you add .macro as a visible file type and move the "show hidden files" to a checkbox rather than a right-click menu so it's more obvious for people setting up the SD card for the first time?

Thanks.
