This is an attempt to document the structure of the eDGe library and the files that are backed up by the Local Backup application.
Local backup of the library creates a file ending in .esi which is actually just a plain zip file. Rename the file extension to .zip and the zip/unzip utilities should be able to examine and manipulate the file. There is no password and no apparent encryption of the file itself.
My edge has the library moved to the external SD card. The .esi/.zip file produced contains two *absolute* paths, /fridge and /sdcard. (This absolute path part may be an issue later when restoring a backup that has had the contents manipulated with zip/unzip on a PC.)
Here is a list of all the directories containing one or more files in the .esi/.zip file:
Code:
/fridge/.edge/.esi-data/.databases/
/fridge/.edge/.esi-data/.edb/
/fridge/.edge/.esi-system/
/fridge/.edge/.esi-system/.fontconfig/
/sdcard/.edge/.esi-content/
/sdcard/.edge/.esi-content/.esa/
On initial perusal it appears /fridge contains a series of sqllite databases. Some contain configuration information, but most are related to library files and used to link separate files together -- books to annotations, etc.
All the real content -- PDFs, annotations, Journals -- are stored under the /sdcard path.
