Should I compress old folders into zip files or move them to an external drive?

\n

Short answer: Zipping saves little on photos, video and music, and makes files unusable until unzipped. Moving to an external drive frees the full size and keeps files opening from the same place; offload rarely used apps.

\n

Zipping only saves space when the contents compress well — text, documents and some app data shrink, but photos, videos and music are already compressed and barely get smaller. A zip also has to be opened before you can use what's inside, and apps that referred to those files lose track of them.

\n

Moving with Storage Studio frees the full size from your internal drive and keeps the files usable: links stay in the original place, so they open as before while the drive is connected, and Move back undoes it. For apps you rarely use, Offload archives the app and its data to the drive and restores it exactly.

Zipping still makes sense for sending a bundle of files to someone, or packing up a finished project you'll never open again. See Moving folders.
