Is there a way to completely reset / regenerate Quick Look preferences (system-wide)?

Quick Look fails to work on many file types that actually have Quick Look plugins and I fear that some file clobbering has occurred during my last two OS upgrades.

When Quick Look fails, the Quick Look preview is a blank page with:

foo<TITLE></HEAD....

Has anyone else run into this issue?


Solution 1:

From the CLI

qlmanage -r will reset the Quick Look cache.
