![]() Course users who have enabled the Files notification preference will not receive a notification when a file is added to a course if the student availability date restriction is selected. If the file is linked in another area of Canvas (such as Modules or Assignments), students will be able to see the name of the file, but if they click the file, they will see a message stating that the file has been locked and cannot be viewed until the specified date. ![]() When the student availability date restriction is set, students cannot view the file in Course Files outside of the restriction dates. Course users who have enabled the Files notification preference will still receive a notification when a file is added to the course if the Only available to students with link option is selected. For instance, if a file with a student visibility restriction is added to a Module or Assignment, the file can always be viewed by students.

The DirectDraw Surface format is useful for storing graphical textures and cubic environment maps as a data file, both compressed and uncompressed. Most image capture devices (such as digital cameras) that output JPEG are actually creating files in the Exif format, the format that the camera industry has standardized on for metadata interchange. Image files that employ JPEG compression are commonly called "JPEG files", and are stored in variants of the JIF image format. The DirectDraw Surface container file format (uses the filename extension DDS), is a Microsoft format for storing data compressed with the proprietary S3 Texture Compression (S3TC) algorithm, which can be decompressed in hardware by GPUs. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography.
