TC has a problems with ICO support or I have a non-stop glitch....)))

[AntonyD]

What about if you test with your original test folders, and then close and restart TC, are the moved icons still shown incorrectly?

yes

But even if the problem really were in this cache, then - WHERE are the settings/commands for managing it?
WHAT can/should be done so that this cache does not influence such moments during the constant operation of Total?

It is Windows' cache not TC's cache - see: viewtopic.php?p=365115#p365115
