By default, Pocket PCs save Notes, Word, Excel, and other documents to the “My Documents” folder in main memory. In most Pocket PCs this is located in RAM, but in the new Windows Mobile 5 devices it will be in “Persistent Storage” (flash ROM). If you prefer to store your documents on a storage card, you can change the defaults in each application to do so. You change this default setting in the Options menu. For example, here’s how you do it in Pocket Word. The process is similar in other applications.
1) Open Word.
2) Tap on the “Tools” menu and select “Options.”
3) In the “Save to:” pull down menu select “CF Card” or “SD Card.”
4) Tap on “OK.”
Now, when you save a document, the Pocket PC will automatically save it in the “My Documents” folder.
Note that documents saved on your storage card will not be synchronized with your desktop PC during ActiveSync.
