Which MIME types are related to file extension ".parquet"?
The .parquet file extension is associated with 1 MIME types:
application/vnd.apache.parquet.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .parquet Files
PARQUET files are used to store structured, columnar data efficiently.
They are built to handle large datasets with high performance. The files use the binary format defined by the MIME type application/vnd.apache.parquet.
Based on information from FilExt.com, here are key facts and uses:
- Column-oriented storage: Optimizes both compression and query speed.
- Big Data integration: Common in Apache Spark, Hive, Drill, and other analytics platforms.
- Efficient data processing: Suitable for running complex queries on massive datasets.
- Interoperability: Works well within modern data warehousing environments.
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
How do I open a PARQUET file on my computer?
You cannot open .parquet files with standard text editors because they use a binary format. To view the data, you need specialized software like Apache Spark, Tad (a dedicated viewer), or programming libraries such as pandas in Python. For quick viewing, VS Code with a Parquet extension is also a popular choice.
Can I open PARQUET files directly in Microsoft Excel?
Excel does not open .parquet files natively by double-clicking. However, you can import them using the Get Data feature (Power Query) if you have the appropriate drivers installed, or you must first convert the file to a CSV format using a tool like Python or an online converter.
Why does the file look like gibberish in Notepad?
PARQUET files are stored in a compressed binary format designed for machine efficiency, not human readability. Unlike CSV or JSON files, they contain encoded data that looks like random characters when opened in a text editor like Notepad.
How do I convert a PARQUET file to CSV?
The most common method is using the Python library pandas. You can load the file using pd.read_parquet('file.parquet') and save it as a CSV with df.to_csv('file.csv'). Alternatively, various online file conversion tools can handle this transformation for smaller files.
What is the correct MIME type for PARQUET files?
The standard MIME type associated with these files is application/vnd.apache.parquet. When configuring web servers or object storage to serve these files, ensuring the correct MIME type helps applications identify the format correctly. You can learn more at mime-type.com.
What are the advantages of using PARQUET over CSV?
PARQUET is a columnar storage format, which means it is highly optimized for performance and compression. It allows for much faster queries when analyzing large datasets and occupies significantly less disk space compared to uncompressed CSV files.
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.
