Hi...
There are three answers .....
If the flash drive has a custom icon then there is hidden files on the flash drive.
An autorun.inf file and a small .ico image file .....
( Click organize > Folder and search options >View>Show hidden folders and files. )
If the flash drive displays a windows created icon the source directory's are..
%SystemRoot%\system32\SHELL32.dll
%SystemRoot%\system32\imageres.dll
If the Flash drive has a custom icon stored on the computer the "original source file " could be any ware.
The image preference retained in AppData..
Select flash drive >Right click>Properties>Customize , i take a good ICT course, can u make this the brainliest?
