Windows Stops Responding When You Click a Large AVI File in Windows Explorer
Article ID: 822430 - View products that this article applies to.
When you click a large Audio Video Interleaved (AVI) file in Windows Explorer, Microsoft Windows may stop responding (hang). Additionally, when you view the Processes tab in Windows Task Manager, you notice that the Explorer.exe process consumes 100 percent of CPU usage for up to two hours or more.
This problem occurs because Windows scans the large AVI file when you click it in Windows Explorer. When you click a large AVI file (for example, when you click a 700-megabyte [MB] AVI file) in Windows Explorer, Windows tries to query the index of the file. If there is no index information in the file, Windows performs a loop to check all portions of the file to build the index. Because of the large size of the AVI file (in this example, 700 MB), it takes a long time for Windows to scan the whole file. Because of this behavior, the CPU usage of the Explorer.exe process reaches 100 percent.
