Which MIME types are related to file extension ".arrow"?
The .arrow file extension is associated with 1 MIME types:
application/vnd.apache.arrow.file.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .arrow Files
ARROW files are files that store data in a columnar format defined by the Apache Arrow standard.
They use the MIME type application/vnd.apache.arrow.file to label the file format.
- Efficient Data Processing: Optimized for high-performance analytic operations and in-memory computations.
- Columnar Storage: Arranges data in columns to enable fast query speeds and low latency.
- Cross-Language Interoperability: Read and written by multiple programming languages using libraries like PyArrow, Apache Arrow C++, and others.
Based on information from FilExt.com, ARROW files are integral in environments where speed and efficient data handling are key.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an .arrow file?
An .arrow file is a binary file format used to store data in the Apache Arrow columnar format. It is designed for high-performance analytics and zero-copy data transfer between different systems and programming languages.
How do I open an .arrow file?
You cannot open .arrow files with standard text editors like Notepad. Instead, you use data processing libraries such as PyArrow in Python, the arrow package in R, or Apache Arrow libraries in C++, Java, and Rust.
Can I open .arrow files in Microsoft Excel?
No, Microsoft Excel does not natively support the raw .arrow binary format. To view the data in Excel, you must first convert the file to a CSV or XLSX format using a script in Python (e.g., using the pandas library).
How do I convert an .arrow file to CSV?
The most common method is using Python with the Pandas and PyArrow libraries. You can load the file into a DataFrame using pyarrow.ipc or pandas.read_feather (if compatible) and then export it using dataframe.to_csv().
What is the MIME type for .arrow files?
The standard MIME type associated with these files is application/vnd.apache.arrow.file. You can verify MIME type configurations and look up related formats on mime-type.com.
What is the difference between .arrow and .parquet files?
While both are columnar formats, .arrow is optimized for in-memory computing and fast data exchange, whereas .parquet is optimized for efficient disk storage and compression. Arrow is often used for processing, while Parquet is used for archiving.
Are .arrow files the same as Feather files?
largely, yes. Modern Feather files (version 2) actually use the Apache Arrow IPC format on disk. Consequently, many tools that read Feather files can also read generic .arrow files seamlessly.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
