With the placeholder preview thumbnails feature, your file manager can present thumbnail previews for placeholder files. This lets you quickly get an idea of the contents of a media file without having to wait for it to be fully downloaded.
Enable placeholder preview thumbnails
Windows
To enable placeholder preview thumbnails for SMB shares on Microsoft Windows workstations:
- Ensure that the
placeholders_as_regular_files_for_smb_servercustom parameter in your job profile does not have value other that1(which is its default value). - In File Explorer open folder options and make sure the Always show icons, never thumbnails option is disabled.
Thumbnail previews may not be supported in certain file managers like Total Commander. In such cases, the system may need to fully hydrate the file to generate a thumbnail. This can lead to a delay in thumbnail display and might require refreshing the contents of the folder.
MacOS
Thumbnail previews for placeholder files accessed over SMB is enabled by default.
To enable thumbnail previews for local placeholder files with the TSS (transparent selective sync) enabled, add the fs_fuse_download_block_list custom parameter to the Agent's profile.
Note that this will clear the default list of MacOS applications blocked from automatically downloading files in TSS, which may result in full download being triggered by performing even the simplest operations on files, such as retrieving file information, or opening a folder.
To optimize local storage usage, enable Progressive Hydration by adding the tss_hydration_policy: 0/1 parameter to the job policy. For details see, File streaming: progressive Hydration in TSS.
Linux
To set up thumbnail previews for placeholder files accessed over SMB, in file manager's preferences, in the Performance section, select the option to show thumbnails for all files.
