You can do factory reset under such case.

Go to Settings -> SD & Phone storage -> Factory data reset.

I don't think an app without root can do it as apps are limited in their own sandbox.

If you mean clearing all app and user data on the phone, you can do a factory reset via Settings -> Privacy -> Factory data reset. Note that this erases all data on the phone, not just app data.

You can try 1Tap cleaner : https://market.android.com/details?id=com.a0soft.gphone.acc.free&hl=en . It works on non rooted devices.

EDIT: Try Clean Master . It scans the memory card for large cache file that you can delete altogether.

unluckily this only clear the cache files.I am looking for erasing data files. –  john smith Feb 7 '12 at 4:15

If you need a fresh phone, reboot in recovery mode and select wipe data. It will format your /cache and /data partitions. Then no data will be there other than your SD card.
