Fine tuning my workflow

[ewg]

I wonder if I could speed up the ExifTool processing and writing even more by:

1. Somehow forcing ExifTool "directly" (or magically) to just modify chosen "CanonVRD" tags in multiple raw image files without physically rewriting/moving all the huge image data on my hdd?

DPP (Canon's proprietary software) is capable of changing and saving diverse 'Picture Styles' settings so quickly - clearly without the wait for the rest of image data to be copied. But it's tricky and useless once you want to change quickly say 'WBFineTuneSaturation' (ExifTool term) values in multiple files with various WB temperatures already set and precious - simply DPP's GUI won't allow that.

2. Omitting the stage of content extraction from exiftool.exe file every time ExifToolGUI starts (initializes ExifTool)?

It's an over 10MB folder with almost 1000 files in over 70 directories... Well, I used to delete them when not in use from my 'temp' directory just for the sake of... hygiene.    Are they all obligatory for Canon raw files modification with ExifTool?

ps Yes, I do have a very slow hdd!

Sorry, ExifTool does not have a write random-access write mode like this.  It is all or nothing.
