Windows File Explorer can take time on some folders as it builds up icons for picture files.
This is not a bug. And I've seen this since Windows 3.0
I've done a clean install of Windows 10 home on my HP Pavillion 3.00ghz, 16GB RAM machine after upgrading my hard drive.
Upon start up, if I for example, open the "downloads" folder, instead of populating the list of files in the directory immediately, I see a "Working On It" message in the address bar. A green bar slowly fills the address bar from left to right and upon crossing the entire screen, my file list appears. This can take 30-60 seconds.
As I mentioned before, this was a clean install of a brand new SSD (Crucial MX300 525GB), so except for the OS, the drive is nearly empty. I can't understand why it is taking so long to load. I've never seen this before on my PC with Windows 7, 8, or 10 (prior to the HD upgrade. I am not sure if it is a quirk of the OS, a problem with the drive (Crucial insists it is not), or perhaps a virus.
Has anyone encountered this before? Advice?
