List of Uniform Resource Identifiers
File type: Internet related file
A uri file is a plain-text list of Uniform Resource Identifiers (URIs), with one URI normally written on each line. The format uses the text/uri-list media type.
It is not tied to a particular application and can be used by software that reads or writes URI lists.

Uniform Resource Identifiers provide a simple and extensible way to identify resources. A uri file stores a list of these identifiers rather than the resource data itself. Lines beginning with a number sign can be used as comments in a URI list.
The URI specification is derived from concepts introduced by the World Wide Web initiative. The use of these concepts dates from 1990 and is described in Universal Resource Identifiers in WWW. URI design also follows requirements described in Functional Recommendations for Internet Resource Locators and Functional Requirements for Uniform Resource Names.
URI lists are platform-independent plain-text files. The associated media type is text/uri-list. The format remains useful where an application needs to exchange a collection of resource identifiers.
A uri file can be opened as text with any plain-text editor on Windows, macOS, Linux, and other platforms. The editor will display the URI entries and any comments but will not retrieve the referenced resources automatically.
Software that supports the text/uri-list format may also open or import the file as a list of resources. If the file does not open as expected, opening it as plain text is the most reliable way to inspect its contents.
A uri file is already a plain-text list, so it normally does not need conversion. To create one in another application, export or save a list of URIs as plain text with one URI per line.
A text editor can be used to edit the entries or change the file extension, but changing the extension does not convert the data. Conversion to another list format is application-specific and should be performed by the software that will use that format.
