Umm, yes, you can, using the simple method I described ...
go to folder options on Explorer, then view tab an tick the "show hidden files and........"ok thanks. i tried hiding the _system_ folder im my sd card, check it out on moonshell. and at last it doesnt show anymore. but when i tried to view it on my SD card, i cant see it either. it was totally hidden, was it supposed to be just transparent to know it was hidden? how can i view that folder i hid?
