Moving the Temporary Internet Files storage cache onto a Storage CardCESD|200186Applies To
OverviewBy default, when you browse the Internet on your Handheld PC, the web pages which you view are downloaded into Storage Memory to improve page load time performance as you navigate back and forward through internet pages. The cache, identified to the system as the Temporary Internet Files cache, also serves as a bandwidth reduction mechanism, preventing pages from being downloaded unnecessarily. This article discusses how to move the cache shell folder from its default position under the Windows folder, onto an external storage device. In addition, the relocation of the shell folders Cookies and History is covered as part of the document. How-to GuideBy default, the Temporary Internet Files cache folder is held within the object store under the folder hierarchy \Windows\Profiles\guest\Temporary Internet Files\. The cache makes use of a series of alphanumeric sub folders to span content from different sites, and with different names within the same cache archive. Content stored within the Temporary Internet Files hierarchy is indexed by the index.dat file located on the root of the cache. WARNING: If you use a Registry Editor incorrectly, you may cause serious problems that may require you to hard reset your Handheld PC back to its factory installed configuration. Edit your Windows CE registry at your own risk.
The Temporary Internet Files path information is stored beneath the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Cache\Paths, this path is assembled by the system ad-hoc, and cannot be manipulated by the user in a functional way. This section of the registry is dynamically built based upon the individual user preference settings of the active Windows CE user account - in this case the guest account - from path information stored under HKEY_CURRENT_USER. Before attempting to alter the location of the shell folders from main memory, the user must consider the implications of removing the Storage medium from the system before or during an Internet Explorer session. Under such circumstances, Windows CE will automatically return the location of the cache to a user profile neutral location at \Windows\Temporary Internet Files. At the next soft reset the store will be returned to the specified folder, however the cache and all of its contents will remain resident in storage memory, and will not be purged by the Clear Cache feature of the Windows CE browser. To change the path of the Temporary Internet Files, Cookies or History shell folders.
Your Internet shell folders will migrate to the storage medium when you next launch the web browser. Notes
