Windows 10: Does ICO containing multiple resolutions matter in loading speed?

Basically the title says it all.
I am using custom icons for my desktop and was thinking if the ICO file contains multiple resolutions (16×16; 32×32; 64×64; etc) does it matter in desktop loading speed and/or memory usage?

:)

 

Some Windows icons become smaller while others remain the right size.

Update: it seems removing Winaero Tweakers effects does not solve the problem, even after restarting the explorer. This issue may stem from the ico file resolution, or a minor bug.

I look forward to your reply.

 

Changing default drive icon in autorun.inf?

Good day,

I've read on numerous sites that in order to change the default icon for a specific drive, all you need to do is create or modify the autorun.inf
file located on the drive's root directory so that it contains the following:



[autorun]

icon=name_of_file.ico



or

[autorun]

icon=subdirectory\name_of_file.ico

The "name_of_icon.ico" file is whatever filename contains the icon that is to replace the default drive icon. After this is done, the properties of these two files would be modified to "read only" and "hidden."

Although this method works great for icon files (.ico) that contain
one icon, I have a question regarding icon files (.ico, .dll, etc) that contain
multiple icons: How can
one specific icon be selected from an icon file that contains many icons? Can it be done using the
autorun.inf file? If so, then would you please let me know how to do it?

Thank you!

 

In theory both load time and memory usage would increase. But in practice the difference would be so trivial you could never measure, let alone notice it. Most icons on the desktop will have multiple resolutions and this is in fact recommended practice.
