-====== Resize system partition dynamically, based on size needed ====== 
  
-   * created by LarsG [[algee2005@gmail.com]] 2015/09/17 
- 
-   * tested under windows 7 
-   * tested under winst 4.11.5.13 
- 
-In case you want your system partition to only use the amount of diskspace required by the system and the applications you install, 
- 
-you can use the following code to extend your system partition dynamically before installing your software. 
- 
-**!!! Warning !!!** 
- 
-Using this can lead to problems if your applications or users are storing data on the system partition. 
- 
-If you want use this, you should consider adopting further measures to prevent possible hickups - f.e. move profiles to another partition, configure your applications to store their data on another partition, prevent write access for users on the system partition.  
-Take care ;) 
- 
- 
- 
-Integrate the following code into your installation script, and change the value of $MinimumFreeSpace$ to the amount of MB required by the software to install; 1 GB equals **1024**, like given as example below. 
- 
- 
-<code winst> 
-[Actions] 
-defVar $MinimumFreeSpace$  
-set $MinimumFreeSpace$ = "1024" 
- 
-if not ( hasMinimumSpace( "%SystemDrive%", $MinimumFreeSpace$ + " MB" ) ) 
- comment "Not enough free space left, trying to extend volume %SystemDrive% by " + $MinimumFreeSpace$ + " MB." 
- execwith_resize_volume diskpart /s 
- if not ( hasMinimumSpace( "%SystemDrive%", $MinimumFreeSpace$ + " MB" ) ) 
- logError "Failed to resize volume, cancel installation" 
- isFatalError 
- endif 
-else 
- comment "Still enough free space left, continue with installation" 
-endif 
-</code> 
- 
-<code winst> 
-[execwith_resize_volume] 
-SELECT volume %SystemDrive% 
-EXTEND size=$MinimumFreeSpace$ 
-</code> 
- 
-This script assumes you install software on your system partition. Otherwise, you need to replace any occurance of %SystemDrive% within my code with the drive letter of your desired partition. 
-f.e. extract it like this: 
- 
-<code winst> 
-defVar $InstallDrive$ 
-set $InstallDrive$ = takeString(0,splitString($InstallDir$,"\")) 
-</code>
