The package cache provides a source of installed packages. You need these packages to repair Visual Studio or other related products when there's no internet connection. With some drives or system set ups, however, you might not want to keep all those packages around. The installer will download them when needed. If you want to save or recover disk space, you can disable or move the package cache.
Disable the package cache
Before you install, modify, or repair Visual Studio or other products with the new installer, you can start the installer with the
--nocache switch to the installer.
"%ProgramFiles(x86)%\Microsoft Visual Studio\Installer\vs_installer.exe" --nocache
Any operation you do on a product will remove any existing packages for that product and will avoid saving any packages after they're installed. If packages are required to modify or repair Visual Studio, they'll be downloaded automatically and removed after their installation.
If you want to re-enable the cache, pass --cache instead. Only packages that are required will be cached. If you need to restore
all packages, we recommend you repair Visual Studio before you disconnect from your network.
"%ProgramFiles(x86)%\Microsoft Visual Studio\Installer\vs_installer.exe" repair --passive --norestart --cache
You can also set the KeepDownloadedPayloads registry policy to disable the cache
before you install, modify, or repair Visual Studio.
Move the package cache
A common system configuration is to have Windows installed on an SSD that has a larger hard disk (or more) for development needs, such as source code, program binaries, and more. If you want to work offline, you can move the package cache instead.
Currently, you can do this operation only if you set the CachePath registry policy before you
install, modify, or repair Visual Studio.
