Is it worth moving small apps to free up space?

Short answer: Rarely — small apps free little space but still depend on the drive. Move or offload a few large apps instead, starting with the biggest.

Rarely. A small app frees very little, yet it still depends on the drive being connected and launches from it. You'll get far more space back by moving or offloading a handful of large apps.

Sort by Size and start at the top; stop when the remaining apps are small enough not to matter.
