PhotoStructure is designed for million-asset libraries, so you shouldn't need to switch between libraries in most cases.

There are 2 ways to change your PhotoStructure library.

The easy way

  1. Shut down PhotoStructure
  2. Rename or unmount your current PhotoStructure library directory. If you can't or don't want to rename this directory, use "the hard way," below.
  3. Start PhotoStructure, and choose "Pick a new library"

The hard way

  1. Shut down PhotoStructure
  2. Delete your system settings file.
    • macOS: $HOME/Library/Application Support/PhotoStructure/settings.toml
    • windows: %APPDATA%\PhotoStructure\settings.toml
    • linux: ~/.config/PhotoStructure/settings.toml
  3. Start PhotoStructure. It should launch into the welcome page.

Note

Uninstalling PhotoStructure doesn't delete your system settings, nor does it delete any library files. If you uninstall PhotoStructure and reinstall PhotoStructure, the previously-selected library will be opened.
