Limit the Pocket IE Cache Size and Avoid Having Low Storage Memory

By Kris Kumar on Monday, January 16, 2006

Do you surf the Internet a lot on your Smartphone's Pocket Internet Explorer browser? It is just a matter of time before you will run into the low storage memory alert. I know I did. Thanks to the sharp QVGA screen and EDGE speeds, I am browsing a lot. The first time I ran into the low storage memory error message, I thought that it was because of my overflowing Hotmail Inbox. But it turned out to be the Pocket Internet Explorer cache, which was holding about 4MB worth of temporary files.

The moment the pIE cache was cleared, my low memory problem was solved. Now I wanted to find out a way to put the pIE on a diet. Mike suggested a quick and simple registry tweak that limits the size of the pIE cache to a manageable level.
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\Cache\Content]

The default CacheLimit setting on my Cingular 2125 had a DWORD value 6126, which meant the maximum cache size was set to 6126KB, approximately 6MB. Confused I lowered it to DWORD value 1536, which represents 1536KB (1.5MB). I would recommend a value between 1024KB (1MB) and 2048KB (2MB). Do not set a value lower than 512KB, because then the cache will not be effective. This tip works on both the Windows Mobile 2003 SE and the Windows Mobile 5.0 based devices. And is highly recommended to our readers who have recently enabled the keypad shortcuts in the pIE browser. Wink Since this change involves editing the registry, I must warn our readers, please take care and backup the data if possible.
