PRB: File Size Limitation on Windows CE

ID: Q180363

The information in this article applies to:

• Microsoft Win32 Application Programming Interface (API) included with:

  - Microsoft Windows CE, versions 1.0, 2.0

SYMPTOMS

The internal file size on Windows CE is limited to 4 megabytes (MB). The same applies to the file size in emulation. This does not apply to external storage, such as a flash card.

STATUS

This behavior is by design.

MORE INFORMATION

WriteFile() does not return an error when the 4 MB is exceeded. The intended number of bytes to be written should be checked against the actual bytes written.
