About .btr Files
BTR files are binary files used by the Btrieve database system. Their MIME type is application/octet-stream.
They hold structured, record-based data. These files speed up operations and support rapid data access in business applications.
- Database Use: Store records in a structured format.
- Enterprise Applications: Common in ERP and inventory systems.
- Performance: Optimized for fast data access and updates.
Based on information from FilExt.com, BTR files remain integral in certain legacy and current business 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
What is a .btr file?
A .btr file is a database file created by the Btrieve transactional database engine, which is now part of Actian Zen (formerly Pervasive PSQL). These files store structured data records, such as inventory lists or financial transactions, commonly used by legacy ERP and accounting software.
How do I open a BTR file?
You cannot open a BTR file with a standard text editor like Notepad. To view or edit the data, you must use the specific business application that created the file or a database management tool like the Pervasive Control Center or Btrieve Commander.
Can I convert a BTR file to Excel or CSV?
Yes, but you usually need an ODBC driver specifically for Btrieve or Pervasive PSQL to read the data first. Once the driver is installed, you can use tools like Microsoft Access or specialized export utilities to query the BTR file and save the results as a CSV or Excel spreadsheet.
Why does the file contain unreadable characters in a text editor?
BTR files are binary files, meaning they store data in a machine-readable format optimized for speed rather than human readability. Because they are not plain text, opening them in a simple editor displays garbled characters; their generic binary nature is why they often use the MIME type application/octet-stream.
Is it safe to delete .btr files?
No, you should not delete these files if the associated software is still in use. Deleting a .btr file will likely corrupt the database and cause permanent loss of critical records, such as customer data or transaction logs.
What is the correct MIME type for serving BTR files?
Since BTR files are proprietary binary data, they are generally served with the generic MIME type application/octet-stream. If you are configuring a web server to handle these files for download, ensure this type is set in your configuration or check mime-type.com for more details on binary stream handling.
What modern software supports BTR files?
While the original Btrieve is a legacy product, modern support is provided by Actian Zen (formerly Pervasive PSQL). Many older business applications, such as certain versions of Sage accounting software, still rely on the underlying Btrieve structure to manage data.
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.
