Help & support

Your archive,
handled with care.

Install and Launch

  1. Install List Studio from the Download page on iPhone, iPad (iOS 18 or later) or an Apple Silicon Mac (macOS 14 or later).
  2. On Mac, press ⌘O to open a CLF file. Select multiple files to open each in a separate window.
  3. The earlier direct-download Mac app is no longer updated. Install the App Store version and remove the old app.

Edit, Copy and Compact

  • Select an item to edit it, or add a new item.
  • Copy a complete list with ⇧⌘C. In another file window, select the destination folder and paste with ⇧⌘V.
  • Compact File removes unused blocks. Press ⌘S to save the result as a new copy.
  • The original file cannot be overwritten. Keep a backup.
  • Find About and Check for Updates in the List Studio menu. Control automatic checks in Settings.

Before Using Edited Files on iPhone

  1. Keep a backup of the original CLF file and your iPhone.
  2. Open a new copy in iPhone ListPro from a Mail attachment or iCloud Drive.
  3. If prompted to replace an existing file, cancel and use a separate test file.
  4. Compare folders, item counts, notes and options. Edit an item, then restart ListPro to confirm that it was saved.

This version has not yet been validated for importing and editing files on an actual iPhone. Automatic two-way synchronization is not included.

Supported Files and Protection

Only the CLF structures examined during development are supported. This version can interpret some protected data without checking its password. Use only files you own or have permission to access. List Studio is not a security tool and does not guarantee password or encryption protection.

Editing is restricted when a file contains unreadable lists. Some fields may remain unsupported. Check a new copy before using it with important records.
