Mac storage basics · External storage and adding space

What's a good way to archive old projects off my Mac?

Short answer: Copy finished projects to an external drive, verify them, keep a second copy elsewhere, label them clearly and check archive drives occasionally before deleting originals.

Move finished work off the internal drive, but keep it safe:

  • Copy the project to an external drive (APFS for Mac-only use) and check it opens.
  • Keep a second copy on another drive or in the cloud — a single archive drive is a single point of failure.
  • Label folders by year or client so you can find things later.
  • Check old drives occasionally; drives left unused for years can fail.

Then delete the originals from your Mac.
