由Nix构建的软件包被放在只读的''Nix存储'', 通常位于<code>/nix/store</code>. 每个软件包会被赋予一个由加密hash值指定的独一无二的地址, 该地址位于软件包名称和版本之后, 例如<code>/nix/store/nawl092prjblbhvv16kxxbk6j9gkgcqm-git-2.14.1</code>. 这些前缀的哈希处理使用到了对构建过程的所有输入, 包括源文件, 完整依赖关系树, 编译器标志, 等等. 这让Nix可以同时安装同一软件包的不同版本, 甚至同一版本的不同构建, 比如由不同的编译器构建的变体. . When adding, removing or updating a package, nothing is removed from the store; instead, symlinks to these packages are added, removed or changed in ''profiles''.

~~Packages built by Nix are placed in the read-only~~ ''Nix ~~store~~'', ~~normally found in~~ <code>/nix/store</code>. ~~Each package is given a unique address specified by a cryptographic hash followed by the package name and version~~, ~~for example~~ <code>/nix/store/nawl092prjblbhvv16kxxbk6j9gkgcqm-git-2.14.1</code>. ~~These prefixes hash all the inputs to the build process~~, ~~including the source files~~, ~~the full dependency tree~~, ~~compiler flags~~, ~~etc~~. ~~This allows Nix to simultaneously install different versions of the same package~~, ~~and even different builds of the same version~~, ~~for example variants built with different compilers~~. When adding, removing or updating a package, nothing is removed from the store; instead, symlinks to these packages are added, removed or changed in ''profiles''.
