FIX: GetFileAttributes and CreateFile take more time when there are more files in a directory in Windows Embedded Compact 7

View products that this article applies to.

This article describes an issue in which GetFileAttributes and CreateFile API take more time when more files are present in a directory in Windows Embedded Compact 7. The time that is taken by API goes from 500 milliseconds per file to 1000 milliseconds per file, and it keeps on increasing. This is a serious issue in the Automotive platform where file indexing never finishes because of this behavior.
An update is available to resolve this issue. Before you install the update, all previously issued updates for this product must be installed.
