Record marked as obsolete and not updated for a long time.
The csj file extension is associated with RIM's BlackBerry Tablet OS SDK for Adobe AIR and BlackBerry WebWorks SDK for Tablet OS. These development tools were available for multiple platforms.
The csj file stores RIM CSJ registration data used by the SDKs for code-signing applications developed for BlackBerry Tablet OS. It is registration data consumed by the SDK rather than a document intended for editing.
The CSJ format is obsolete.
Use the BlackBerry Tablet OS SDK for Adobe AIR or BlackBerry WebWorks SDK for Tablet OS to work with a csj file for registration and code-signing purposes. The file is not intended to be opened as a document in a general-purpose application.
A csj file is registration data for the BlackBerry SDKs, not a document or media file, so it cannot be meaningfully converted to another format. The original SDK must use the file in its original form.
