This guide will share some tips to reduce the size of an install by deleting obsolete content. Keep in mind:

• The commands mentioned in this guide will permanently override/delete data. Ensure you won't be sorry!
• As per usual, never run Warframe.x64.exe without sideloading the Bootstrapper to avoid corrupting the install.

Flushing An Update Patch

Update patches work by providing (updated) content which the game can request on demand, but this means you need to have a copy of this content in OpenWF/Content, taking up 1.53 GiB in the worst case. You can run the content update applet to "flush" this content into the Cache.Windows folder:

1. Warframe.x64.exe -silent -log:/Preprocess.log -graphicsDriver:dx11 -language:en -applet:/EE/Types/Framework/ContentUpdate
   • Note the dx11 and en in this command. For every configuration you intend to use, run the command accordingly.
2. Delete the OpenWF/Content folder.

Defragging The Cache

If you downloaded a user install or flushed an update patch, the Cache.Windows folder may contain old versions of some content, which can be cleaned up as follows:

• >= U38.6: Warframe.x64.exe -silent -log:/Defrag.log -applet:/EE/Types/Framework/CacheDefraggerIOCP /Tools/CachePlan.txt
• < U38.6: Warframe.x64.exe -silent -log:/Defrag.log -applet:/EE/Types/Framework/CacheDefraggerAsync /Tools/CachePlan.txt
