How To Change Default Install Location [patched] May 2026

sudo flatpak --system override --filesystem=/mnt/bigdrive/flatpak flatpak install --user --reinstall flathub app-id Snap locations are hardcoded ( /snap , /var/lib/snapd/snaps ). Workaround: symlink:

robocopy "C:\Program Files" "D:\Program Files" /E /COPYALL /DCOPY:T rmdir "C:\Program Files" /S /Q mklink /J "C:\Program Files" "D:\Program Files" Repeat for C:\Program Files (x86) if needed.

# Create user Applications folder if missing mkdir ~/Applications defaults write com.apple.installer TargetDirectory -string "/Volumes/Data/Applications" how to change default install location

# Install Homebrew elsewhere export HOMEBREW_PREFIX="/opt/homebrew" /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" Or migrate existing:

sudo systemctl stop snapd sudo mv /var/lib/snapd /mnt/bigdrive/snapd sudo ln -s /mnt/bigdrive/snapd /var/lib/snapd sudo systemctl start snapd Set in ~/.bashrc or ~/.config/environment.d/ : improves performance for large applications

export PATH="$HOME/bin:$PATH" export LD_LIBRARY_PATH="$HOME/lib:$LD_LIBRARY_PATH" export PKG_CONFIG_PATH="$HOME/lib/pkgconfig" export CMAKE_INSTALL_PREFIX="$HOME/.local" Build tools respect DESTDIR :

./configure --prefix=/mnt/bigdrive/usr/local make && sudo make install For , no global default change — use bind mounts: including native settings

1. Executive Summary Changing the default installation directory prevents system drive (C:) saturation, improves performance for large applications, and enables logical separation of OS and programs. However, modifying this setting incorrectly can break system updates, application functionality, and security permissions. This report provides authoritative methods for Windows, macOS, and Linux, including native settings, symbolic links, and environment variable manipulation. 2. Windows 2.1 Native Method (Registry & Settings) Scope: Affects new installations via standard MSI installers and some UWP (Store) apps.
