I can't find the simplest of information on anything for Droid Explorer. For instance, I did a backup, the backup screen disappeared, where does it put my *.ab file?
Does the Droid Explorer app have documentation?
Documentation for Droid Explorer can be found on the GitHub repository's wiki.
Disclaimer: I am the lead developer on Droid Explorer.
As corti.nico said, those are the locations to find documentation. Documentation is very sparse. I am always looking for someone to help with creating documentation.
To answer where the backup file is saved, it is put in %USERPROFILE%\Android Backups
. This is not currently configurable, but I have been working on making that configured as part of the install.
