Question on whether data or cache files remain after Irfanview 64 is exited normally.

[cfcboc]

After using Irfanview 64 (Windows 10) and exiting the program normally, are there any cache files or data files that remain post-session that would contain copies of images viewed with Irfanview?

If so, where can I find such files? I don't see any file locations in the Properties/Settings menu.
