Windows Explorer memory usage normal?

Good morning,
I have noticed in the recent days (it may be nothing) but Windows Explorer is using a fair bit of RAM. I noticed the usage will continue to grow when opened. I guess this is normal behaviour, the issues I am seeing is the usage does not seem to go back down. I have had it sitting at over 700MB usage. I can get this to go down manually by resetting the task but surely I shouldn't need to do this? Again this may or may not be a lot, this is why I am here to ask this question. Is this normal behaviour?

Windows 11, chipset etc are all up to date.
CPU - 7800X3D
GPU - 4090
RAM - 64GB @ 6000mhz
Windows is installed on a 1TB M.2 SSD

Thanks for taking the time to read through.
Dan.
