Symptoms

When there's a very large number of files in a directory in Windows Embedded Compact 2013, the GetFileAttributes and CreateFile functions take longer than expected to run. The time that's taken by these functions grows 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 sometimes never finishes because of this behavior.
