Understanding SnapShot
The SnapShot program (note the terminology uses upper case S's in the naming convention for this program) manages multiple instances of the JD Edwards EnterpriseOne Development Client on a single machine. Using this program you can save and restore copies of an installed Development Client. A saved copy is called a "snapshot" (note the terminology uses lower case s's in the naming convention for this entity).
Below is an example of SnapShot managing multiple tools releases including E920 and two installations of E910 (B9_Perf and E910_aaa).

The preceding image shows the JD Edwards main SnapShot window. The main features of this window, from top to bottom, include:
