UE-DDCTool

Description

Unreal Engine uses a DerivedDataCache, which it usually creates somewhere on your system boot drive. For most people, this is a smaller SSD that's only supposed to contain your Windows install and assorted programs, not a directory full of small files that can quickly bloom into the dozens of gigabytes.

You can edit your BaseEngine.ini to point an Unreal Engine version at another directory, but every time you update, this gets reset and if you forget to edit it again, you end up back where you started: with lots of unwanted data on your boot drive.

With this tool, it's just a question of remembering to run it and clicking apply next time you patch your Unreal Engine install.

Features

• Finds UE versions on your system, installed via the launcher or your own source builds
• Tries to find the right names to identify your source builds, but allows you to change them
• Allows you to specify a new directory to save the local DDC to, and remembers it
• Can run the editors or open the UE4 solutions for source builds, where applicable
