The Blob service provides storage for entities, such as binary files and text files. A container is like a folder, containing a set of blobs; every blob must reside in a container. The Blob service defines three types of blobs:. Block blobs, which are optimized for streaming. This type of blob is the only blob type available with versions prior to Page blobs are available with version and later.
Append blobs, which are optimized for append operations only. Append blobs are available only with version and later. Containers and blobs support user-defined metadata in the form of name-value pairs specified as headers on a request operation. Blob names may encode a hierarchy by using a configurable path separator. The enumeration operation for blobs supports traversing the virtual hierarchy in a manner similar to that of a file system, so that you can return a set of blobs that are organized beneath a group.
A block blob may be created in one of two ways. You can upload a blob with a single Put Blob operation, or you can upload a blob as a set of blocks with a Put Block operation and commit the blocks to a blob with a Put Block List operation. Page blobs are created and initialized with a maximum size with a call to Put Blob.
To write content to a page blob, you call the Put Page operation. Append blobs can be created by calling Put Blob. An append blob created with the Put Blob operation does not include any content. To write content to an append blob, you add blocks to the end of the blob by calling the Append Block operation. Updating or deleting existing blocks is not supported. Recommendation: Preinstall on devices that will be shipped to a retail store. Install the language-neutral FOD, as well as at least one language-specific FOD to ensure that any Windows 10 device can be used as a demo device.
See Retail demo experience for more information about configuring RDX. This Feature on Demand package adds the Connect application which allows other devices to wirelessly project to this computer. Recommendation : Only include if you need the capability to receive wireless projections. This feature is not required to wirelessly project to another device. The following is a list of additional FODs you can add to your Windows image to enable additional functionality based on your hardware configuration or to support additional use cases.
This Feature on Demand enables Braille devices to work with the inbox Narrator screen reader. Without this Feature on Demand, Braille drivers and translation tables will be missing, causing Braille to not function properly. Recommendation: Don't include these Features on Demand in your image, as doing so could conflict with Braille device rights restrictions.
An on-device diagnostic platform used via a browser. Enabling Developer Mode will attempt to auto-install this Feature on Demand. If this Feature on Demand is not successfully installed, device discovery and Device Portal can't be enabled, preventing remote deployment to the device. Recommendation: In general, don't preinstall on devices. If you are building an image for "developer edition" devices, where the primary market for the device is developers or users who plan on developing or testing UWPs, consider preinstalling.
Used for Direct3D application development. It is typically installed by AAA game engine developers, enterprise graphics software developers, or niche hobbyists. Recommendation: Don't install. This Feature on Demand is only needed by specific users who can trigger installation through Visual Studio when certain optional packages are chosen at install.
This feature has been deprecated and is only needed to support legacy hardware. This was previously available as a separate download. If you are building an image for "developer edition" devices, where the primary market for the device is developers or users who plan on testing websites in Microsoft Edge or web content in UWPs, consider preinstalling.
This Feature on Demand adds Notepad, enabling plain text documents and source code files to be instantly viewed, edited, and searched. On images where the Notepad app is preinstalled, the Notepad system Feature on Demand is used instead of the Notepad Feature on Demand.
