* Input: {local.registry.currentuser/Software/Microsoft/Windows/CurrentVersion/Explorer/Shell Folders/AppData}
* Output: C:\Users\\*username*\AppData\Roaming

{% hint style="info" %}
Registry keys should start like this:

* classesroot for HKEY\_CLASSES\_ROOT
* currentuser for HKEY\_CURRENT\_USER
* localmachine for HKEY\_LOCAL\_MACHINE
* users for HKEY\_USERS
* currentconfig for HKEY\_CURRENT\_CONFIG
  {% endhint %}

{% hint style="warning" %}
Registry paths should use / (forward slashes) instead of the usual \ (back slash)!\
\
Using \ will result in a fail with the error "1>0"
{% endhint %}
