The batch import dialog allows you to choose whether or not to make copies of the original files. If you copy to Internal Storage, you will never be able to browse to the files, as they are made hidden to everything except MobileSheets. If you choose External Storage, they are copied to /sdcard/Android/data/com.zubersoft.mobilesheets/files (this can vary depending on the directory your specific tablet chooses for external storage). You can also choose removable storage if you have an external sd card, and you've specified the directory in the options. Here is a little trick too - you can always just specify any directory on your tablet that you want as your Removable Storage, so long as it is a folder that any app can write to.
