Which MIME types are related to file extension ".fsa"?
The .fsa file extension is associated with 2 MIME types:
text/x-fasta, application/octet-stream.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .fsa Files
FSA files are used in two distinct ways based on their MIME types.
They can be plain text files under the MIME type text/x-fasta. These files follow the FASTA Database Format used in bioinformatics. They store nucleotide or protein sequences in simple text. They are easy to read with basic text editors and are often processed by tools such as BLAST or BioEdit.
- Use Case: Storing DNA, RNA, or protein sequence data.
- Format: Plain text, human-readable.
- Software: Text editors and bioinformatics applications.
They can also be binary files under the MIME type application/octet-stream. In this case, FSA files contain animation data used by Farscape: The Game. This type is not meant to be edited with a normal text editor and needs specific game engines or animation viewers to open and process the data.
- Use Case: Storing game animation sequences and related data.
- Format: Binary, not human-readable.
- Software: Game-specific tools or dedicated animation viewers.
Based on information from FilExt.com, use the proper tool for each type of FSA file to ensure you can view or edit its contents correctly.
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.

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.
