Can't open .PROTO file? Are you wondering what it contains? On our site we will explain to you what this file is, what it is used for and what software opens the .PROTO file.
.PROTO file extension is created by Google. .PROTO has been classified as Developer Files. The format of .PROTO file is Text.
Developer file created in Google's Protocol Buffer format, a data serialization format used for exchanging data; specifies one or more "messages" as logical records, each of which contains name-value pairs (e.g., a Person message may have an ID, name, and address); designed as an alternative to XML for data exchange.
Once a protocol buffer's schema has been specified, you can use the Google Java, C++, or Python protocol buffer libraries ("protobuf") to auto-generate source code. Once generated, the source code can be used in your program for creating structured data and reading and writing it to input and output streams.
Protocol buffers are used for serializing objects from Java, C++, or Python programs. This allows data to be encoded in a common format and exchanged between applications written in the three languages.
NOTE: Protocol buffers are used by almost all of Google's in-house file formats and RPC protocols.
