# How to Change the Size of the FileSystem Cache


You can change the size of the FileSystem cache by using the command line. This action requires a complete reset of the cache, and it requires administrative rights.

**To change the size of the FileSystem cache**

1.  Set the following registry value to 0 (zero):

    HKEY\_LOCAL\_MACHINE\\SOFTWARE\\Microsoft\\SoftGrid\\4.5\\Client\\AppFS\\State

2.  Set the following registry value to the maximum cache size, in MB, that is necessary to hold the packages—for example, 8192 MB:

    HKEY\_LOCAL\_MACHINE\\SOFTWARE\\Microsoft\\SoftGrid\\4.5\\Client\\AppFS\\FileSize

3.  Restart the computer.
