If your digital camera or camcorder use MTS format, it is a PIA to open the folder of MTS files:
You may make a shortcut to this folder, but, if you are like me who uses lots of external USB storage devices, the "G" changes all the time from D to H.
Here is a better solution:
Right click on your desktop, New, Text Document, name it as OpenV.bat. Then right click on this file, Edit, copy and paste the following line (single line):
for %%d in (d e f g h) do if exist %%d:\PRIVATE\AVCHD\BDMV\STREAM explorer %%d:\PRIVATE\AVCHD\BDMV\STREAM
and save the file.
From now on, once you inserted the SD card from your camera, simply double click on the OpenV.bat file and it'll open the video folder for you:
You may download this OpenV.bat here. You may unzip it to anywhere in your computer and then create a shortcut on your desktop.
