i dont recall where i got this function/ tool/ program or what ever it might be. i just assumed it came with the DIRECTORYOPUS program. so right now i have no more info to give you.
the jpg shows where QUICKACCCESS folders are in DIRECTORY OPUS. to "put" a folder into QA i just right click and select "add to QA"
also as i recall the F5 key would activate it but alas no more.
as i recall when the QA blue star was pressed DO showed all the drives as well as the RECYCLE BIN. this was a quick and easy way to access the recycle bin.
