Folder which apps are downloaded to in Curtis 7029 Tablet using appsinstaller

[zhong]

Could someone please tell me where the apps are downloaded to in Curtis 7029 Tablet, if I don't have micro sd card ?

It is in internal storage directory somewhere ?

If so, what is the path ?

I wish to cut and paste apk files to sd card to save internal storage space.

I am using appsinstaller from Android Market.

I am using ES File Explorer to browse.

Thanks.
