Making Changes to the Sandbox

VMware does not support modifying or adding files directly to the sandbox. If you copy files to the sandbox directory, the files are not visible to the application.

ThinApp stores file system information in the virtual registry. The virtual registry enables ThinApp to optimize file system access in the virtual environment. For example, when an application tries to open a file, ThinApp does not have to consult the real file system for the real system location and again for the sandbox location. Instead, ThinApp can check for the existence of the file by consulting only the virtual registry. This ability increases the ThinApp runtime performance.

If a file already exists in the sandbox, you can overwrite and update the file. VMware recommends that you perform all modifications from the application itself.
