Note: End of Life (EOL) has been announced for Box Sync effective December 2026. For more information visit the official announcement page.

Note: Box Sync is not supported on Apple Silicon devices. Users on these devices need to switch to Box Drive.

Overview: Box Sync mirrors selected Box content to your desktop for offline access. Performance can degrade if too many files or highly active folders are synced. This guide explains how to optimize what you sync to keep Box Sync fast and reliable.

Problem: Box Sync is slow or resource-intensive due to syncing high-activity folders or large volumes of rarely accessed content. Excessive file counts and frequent changes increase scan and upload/download times.

 

Process for Resolution:

  1. Open Box on the web and review currently synced folders.
  2. Identify high-activity folders (many collaborators, frequent edits/comments/tasks).
    • If a folder is high-activity, go to Step 4.
    • If not, go to Step 3.
  3. Reduce total synced items.
    • Unmark for sync any folders you rarely access.
    • Sync only the lowest-level subfolder you need, not entire parent folders.
  4. Adjust sync scope for high-activity folders.
    • Sync only the specific subfolders you actively work in.
    • If collaboration is heavy across many files, consider unsyncing and using Box on the web for those areas.
  5. Verify you are within supported limits.
    • Keep total synced files under 100,000 and storage under 100 GB.
    • If near limits, further narrow what is synced.
  6. Apply changes in Box drive/folder settings and allow Box Sync to re-scan.
    • Keep your device powered and connected to the internet while changes complete.
  7. Confirm performance improvement (reduced CPU/network usage, faster sync status changes).

 

Outcome:

  • Box Sync completes scans and updates faster, with lower CPU and bandwidth usage.
  • Only frequently accessed, right-sized folders stay synced, improving reliability.

 

Alternatives:

  • Use Box on the web for high-activity or large folders instead of syncing.
  • Leverage Box Drive (if available) for on-demand access without fully syncing content.
  • Temporarily pause sync during peak work times, then resume off-hours.
  • Escalate to IT or Box Support with logs if performance remains poor after scoping changes.
