When i copy a file into USB larger tham 1GB my system lags. What can i do??
What are your hardware specs? Are you using usb 2, 3, type C? It may just be that it puts a load on your hardware when you move something of that size to a usb drive. What file manager are you using? What desktop environment? Are you using LTS or current kernel?
<some elaboration may be required>
~thank you ^_^
