Configuring File Storage 10
You can modify ThinApp parameters to configure file storage and set up virtual drives.

CachePath Parameter
The CachePath parameter sets the deployment system path to a cache directory for font files and stub executable
files.
Because of the frequent use of font and stub executable files, ThinApp must extract files in the cache quickly
and place them on the physical disk.
If you delete the cache, ThinApp can reconstruct the cache.
You can use the THINSTALL_CACHE_DIR environment variable to override the CachePath parameter at
runtime. If you do not set the THINSTALL_CACHE_DIR environment variable or the CachePath parameter,
ThinApp sets an initial value for the CachePath parameter based on the SandboxPath parameter. The value is
set according to the following rules:
n
If the SandboxPath parameter is present in the Package.ini file and uses a relative path, the CachePath
parameter uses the sandbox path and stores the cache at the same directory level as the sandbox.
n
If the SandboxPath parameter is present in the Package.ini file and uses an absolute path, or if the
SandboxPath parameter does not exist in the Package.ini file, the CachePath parameter uses the %Local
AppData%\Thinstall\Cache location. This places the cache directory on the local machine, regardless of
where the user travels with the sandbox. ThinApp creates a Stubs directory within the cache.
Example: Setting an Absolute Path
You can modify the CachePath parameter to use an absolute path.
CachePath=C:\VirtCache
Example: Setting a Relative Path
You can set a relative path that ThinApp detects as the path relative to the directory where the application
executable file resides. If the package resides in C:\VirtApps and the CachePath parameter has a value of
Cache, the cache directory is C:\VirtApps\Cache.
