Remarks

For better performance, content-based thumbnails are stored in the location specified by the ThumbnailFolder property.

Important

Note that the folder that containing thumbnails must be placed physically inside the application folder.

Note

• By default, thumbnails are created in the public “thumb“ folder that can result an unauthorized access to private files’ thumbnails.
• Thumbnail folder structure is based on the source folder relative paths. Therefore, if you change the root folder dynamically, incorrect thumbnails can be displayed.

We recommend you dynamically specify a thumbnail folder and set restricted access for these thumbnail folders to prevent the issues described above. To learn more, see the Security Considerations topic.
