Index Files

Index files on the server for a mounted connection in the background after connecting to ensure you can browse all directories when offline. Enabling this option will make sure new files available on the remote storage are detected without manually choosing Reload in the context menu. When enabled, remote directories previously opened are polled for changes and new files periodically every 10 minutes.

Warning

This feature is not available in Online connect mode. You cannot browse folders or open files as soon as the server connection gets interrupted.

Enable Buffering

Choose whether the file contents should be buffered. The option allows buffering file contents in a temporary location which is only deleted when quitting the application.

  • Allows faster access when reading or writing files with random access patterns from applications in Online mode.

  • With the option enabled in Smart Synchronization mode, buffered file contents will be copied to the cache and the file can be opened when offline. Refer to Status of Files.

Lock Files

Enable to prevent conflicting edits when accessing documents from a shared environment. Refer to File Locking.

Mount Location

macOS only

Volumes are mounted in the Volumes folder in the application support directory. You can change the default to another folder that is writable.

Note: You cannot set it to /Volumes on macOS Mojave (10.14 or later) where the directory is not writable. The setting is not available in the version from the Mac App Store. The default is set to ~/Library/Group Containers/G69SCX94XU.duck/Library/Application Support/duck/Volumes.

Cache Location

Change the location where to store cache files required for offline access. By default the Cache folder is in the application support directory. The disk must be formatted as HFS+ or APFS.

Warning

Do not manually move, delete or modify files in the obfuscated local cache location.

Cache Limitations

Periodically free up space with cache limitations to purge unused files from the cache at regular intervals in the background keeping only a placeholder with metadata. You can choose a limit for the synchronization cache per bookmark and can select a timeframe for unused files to be purged.

The following options are available:

  • Limit by size. Limit cache size per bookmark by selecting a maximum folder size within the preference. Exceeding the maximum cache size, larger files are purged first.

  • Limit by time. Purge files not accessed within a selected period of time automatically.

Tip

Files selected to always keep offline are never automatically removed from the cache.

By default, files are kept in cache for 30 days and the cache is limited to a maximum size of 5GiB.

Attention

The settings apply separately for each bookmark which must be connected for the cache management to run.

Notifications

Set which type of notifications you want to receive. Alternatively, you can choose Open System Preferences to disable the notifications all together. The following types of notifications can be toggled:

  • Filesystem mounted. The volume is now connected.

  • Filesystem unmounted. The volume has been disconnected.

  • Pause Sync. Synchronization has paused due to the server not reachable because of a network or login error.

  • Resume Sync. Synchronization has automatically resumed as after reachability change.

  • File Added. New file has been found on the server not previously synced.

This way you will no longer be disturbed by any notification displays, but can still check back the notifications in Notification Centre anytime if required.

The connection profiles will be installed after ticking the corresponding checkboxes. Installed protocols are displayed in the protocol dropdown menu in the bookmark window.
