Windows Disk Space Requirements—
1.4.2 SDK/JRE Installation


Note:

Due to a bug in the Beta release of 1.4.2, 371MB or more of free disk space are required for the Windows SDK installation. This bug will be corrected in the GA release.

For both the SDK and the JRE, the user is given the option of installing various features. For the JRE the features are the following:

Feature 1: Java Runtime Environment
Feature 2: Support for Additional Languages
Feature 3: Additional Font and Media Support

For the SDK the features are the following:

Feature 1: Development Tools
Feature 2: Demos
Feature 3: Source Code
Feature 4: Public Java Runtime Environment

Notes:

  • For the SDK the installed image consists of all the files installed under ../j2skd1.4.2; for the JRE it consists of all files installed under ../j2re1.4.2. The update repository consists of zip files for the various features. They are stored under Program Files/Common Files/Java and are used for the purpose of updating or modifying the SDK or JRE.
  • The installed image will, by default, be installed on the Windows drive—the drive where the Windows operating system is installed (sometimes called the system drive). Most often this will be the C drive. However, it is possible to install them elsewhere. For instance, the installed image for the SDK could be installed to a non-Windows drive with a custom installation. (Note, however, that if Feature 4 is selected—Public Java Runtime Environment—it will be installed on the Windows drive.) For a custom installation of the JRE, Feature 1, the Java Runtime Environment, could also be installed to a non-Windows drive.
  • The update repository will always be installed on the Windows drive.

In addition to the disk space required for the installed images, there must be sufficient disk space for the update repository, located in the Program Files/Common Files/Java subdirectory. The table below shows the various disk space requirements for the JRE and SDK:
