In one of my photo folders, I have a 3.8 GiB TIFF image file. With automatic thumbnail generation set, explorer completely locks up my system when accessing the folder. By inspecting the Resource Monitor, I was able to see that explorer was trying to read the TIFF file at normal priority. Disk IO was thus locking up the system. Also, the memory consumption of explorer grew huge (more than available RAM), so the system was also trying to access the pagefile at the same time it was trying to read the TIFF file.
I had to force a shutdown to get back to my system. I turned off the thumbnail setting and I was now able to look inside the folder. But as soon as I single clicked on the file, explorer tried to read the entire file and locked up the system. I assume the right hand side quick preview was responsible for this lockup.
Can I specify a maximum file size that Windows should not attempt to thumbnail like in Adobe Bridge? Any other suggestions?

You can disable thumbnail generation for only
.tifffiles, but this cannot be done by file size as of yet. The key is located at:HKEY_CLASSES_ROOT\.tiff\ShellEx\{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}Simply delete the
{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}key. You will want to back up the key first to restore this functionality if you want it back later on.
