Symptoms

Consider the following scenario:

  • You run a Windows Embedded CE 6.0 R3-based image on a device that uses the FAT file system.

  • You copy hundreds or thousands of files from one folder to another folder.


In this scenario, the speed of copying the files is not consistent. The speed becomes slower during the copying process.

Cause

This issue occurs because file manager does not correctly handle copying lots of files from one folder to another folder on a FAT file system disk when the disk cache becomes full.
