Hi Recently i've customized folder icon on root of the drives by using the following code Code: [.ShellClassInfo] IconResource=myicon.ico,0 and saving the files as "desktop.ini" along whith the icon file myicon.ico inside the folder. Pixel dimension of each icon is 256 x 256 & filesize = 361KB I can feel the time increased in browsing the root drives & opening my computer, its taking noticeable amount of time to display all drives/icons. the only changes i have done recently are:- 1. installing SP1 2. customizing directories 3. Adjusting pagefile from "system managed" to "min:1GB max:12GB" Im wondering if, customizing directory icons affect the performance of the PC ? i have over 10 - 15 folder on the root of each drive. CPU: AMD Phenom II X4 955 3.2 GHz RAM: 6GB GPU: ATI HD 5870 Display: Dell U2410 OS: Win7 x64 Ultimate HD: WD 320 GB SATA Blue Edition & WD 1TB SATA2 green edition I dont feel the lag while browsing folder containing 100's of images in large thumbnail, but "my computer" And the root directory of the drives taking atlest 3sec to display drive icons for the first time Please advice. PS:- cant turn on the option to show icons instead of thumbnail, i work on photograph & i use that feature browsing images.
