FileLever documentation
Protect valuable data. Keep backups in sync. Preview every change.
Learn in a safe order: keep backup copies up to date with sync and archival, preview what will change, then clear extras from exact duplicates or large files when you are ready—on your Mac or in Dropbox after you connect it.

Popular workflows
Start with the file outcome you need
Use these task-led walkthroughs when the job is larger than a single setting or feature question.

Multiply photo, video, design, music, or collection backups across an external drive and Dropbox—preview what changed before you update each copy.
Plan a media backup
Reclaim space from exact duplicates
After backups are current, confirm exact duplicate imports, downloads, exports, or old copies—then remove extras only after you preview the plan.
Review duplicates
Reclaim space from large projects

Google Drive workflows
Protect Google Drive copies you can’t lose. Use folders that Google Drive for desktop keeps on your Mac, keep backups up to date, then free up space with a preview.

Protect copies you can’t lose. Connect Dropbox directly to keep backups up to date with folder sync, then free up space with duplicate and large-file review.
Safety guides
Preview before you clear extras, and verify the release files you download.
Verify checksums
Verify a downloaded FileLever release file with checksums before you install it, especially before opening a new desktop build.
Delete safely
Free up space only when a backup is in place. Preview every removal in mirror, duplicate cleanup, or large-file review so protected copies stay intact.
