Obsidian Portable based on PortableApps Launcher, with a batch file for easy install / upgrade.
The AdditionalParameters entry allows you to pass additional command-line
parameters to the application.
The RunLocally entry allows you to run the portable application from a read-
only medium. This is known as Live mode. It copies what it needs to to a
temporary directory on the host computer, runs the application, and then
deletes it afterwards, leaving nothing behind. This can be useful for running
the application from a CD or if you work on a computer that may have spyware or
viruses and you'd like to keep your device set to read-only. As a consequence
of this technique, any changes you make during the Live mode session aren't
saved back to your device.
To run multiple instance of obsidian, make a new application folder and rename it. This will allow you to open the same / different vault.
