问题
I seem to have a TON of them in subfolders named for example
sprockets%2F76920e6913c3390459175ac8e6dfd44a3
They seem to contain binary data.
What are they for, why are there so many of them and most importantly, can these be safely removed? They take forever to scp.
回答1:
Yep! You can delete the whole tmp directory and it will get recreated.
回答2:
Yes, you can safely delete it.
The best way to delete will be running the following in the rails console:
Rails.cache.clear
