Acquire the data from your camera(s) and place it in a folder called 1-Transit.
This data is stored here until you act upon it.
Sort the data. While you sort be sure to move to another folder called 2-Sorted
Here you can categorize, convert and process your information.
Make a backup copy somewhere else and after doing so move files to a folder called 3-Save
This way you can quickly identify which data is already a copy versus data that needs to be copied
Make a second copy and remove the originals or move to a folder called 4-Temp
This allows you realize some disk savings by removing without risk of lost data.
Please post comments, this is WIP.
