Leaving Encrypted Partition Unlocked?

This is probably a really basic question (yes, I've searched) but I have a question about how encryption works. Say I have an encrypted partition that I unlock every time I log in, is the data at risk if the partition sits there unlocked while I use my computer? I would imagine it would be as backup programs for instance have access to it so any malicious program could too but I haven't read anything about this.

 

While an encrypted partition is unlocked, it's effectively not encrypted. Any copies made while it's unlocked (unencrypted) won't be encrypted after it's locked. That includes swapfiles, tempfiles and logs for both the OS and any apps that you use. To avoid leaks, you either need to use whole-disk encryption, or wipe all swapfiles, tempfiles and logs.
