The Archiving option, accessed via your Android device's Menu key, lets you back-up (copy) the currently open book to the device's SD-Card or to send it as an email attachment. Previously backed-up books may also be restored from the SD-Card into the book list.
Books backed-up to the SD-Card may be found in the folder
/sdcard/Android/data/uk.jatman.android.kittybanker/files
.
Note: this folder and all its contents will be deleted if you
uninstall the KittyBanker application from your device.
