How to Clean .NET NuGet HTTP & Temp Cache
Location & Quick Verdict
%LocalAppData%\NuGet\v3-cache and %LocalAppData%\Temp\NuGetScratch
Visual Studio and the .NET SDK cache downloaded NuGet HTTP responses and scratch packages in %LocalAppData%\NuGet.
Why Package Tarballs, Symbol Indexes & Build Artifacts Pile Up in .NET NuGet HTTP & Temp Cache
Developer toolchains, language package managers, and modern IDEs cache every downloaded dependency version, pre-compiled wheel/crate tarball, C++/Rust incremental build target, and Language Server Protocol (LSP) AST index inside %LocalAppData%\NuGet\v3-cache and %LocalAppData%\Temp\NuGetScratch. Because dependency lockfiles evolve every week, historical versions from old branches remain cached indefinitely—turning .NET NuGet HTTP & Temp Cache into a multi-gigabyte graveyard of thousands of small files.
Thousands of small cache entries inside %LocalAppData%\NuGet\v3-cache and %LocalAppData%\Temp\NuGetScratch also degrade Windows Defender real-time filesystem scanning and slow down backup indexing. Cleaning .NET NuGet HTTP & Temp Cache reclaims 2.0 GB – 16.0 GB of SSD capacity while preserving your active source code repositories, .env secrets, SSH keys, and workspace configurations.
