Which MIME types are related to file extension ".flt"?
The .flt file extension is associated with 2 MIME types:
text/plain, application/octet-stream.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .flt Files
FLT files are used in different ways depending on the software context. They may be simple plain text files characterized by the MIME type text/plain or binary files marked by application/octet-stream.
When used as plain text, these files serve as filters for WinMerge. They define rules to include or exclude specific directories and files during comparisons. You can open them with any text editor.
When used as binary, they are associated with ImgStar and function as bitmap images in a proprietary format. Specialized image software like ImgStar is needed to view or edit these files.
- WinMerge Filter: Plain text files that list criteria to filter directory or file comparisons.
- ImgStar Bitmap: Binary files that store image data in a specific bitmap format.
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 .flt file used for?
The .flt extension is primarily used for WinMerge Filters or ImgStar Bitmaps. As a WinMerge filter, it contains text rules for comparing files, whereas the ImgStar format stores binary image data. In some contexts, it may also relate to 3D OpenFlight databases used in flight simulation.
How do I open an .flt file?
If the file is a WinMerge filter, you can open and edit it with Microsoft Notepad, Notepad++, or any text editor. If it is an image or 3D model, you must use specific software like ImgStar or a compatible 3D viewer, as text editors will only display unreadable symbols.
Why does my .flt file look like random characters?
You are likely trying to view a binary ImgStar Bitmap or a 3D model file inside a text editor. These files use the application/octet-stream MIME type and require specialized software to interpret the binary data correctly; text editors are only suitable for the plain text filter variation.
How do I create a filter for WinMerge using .flt?
You can create a new text file and save it with the .flt extension. Inside, you define lines starting with def: to include or exclude specific file patterns (e.g., f: \.bak$) during comparison operations.
Can I convert an .flt image to JPG or PNG?
Yes, but you generally need the original ImgStar software or a specialized legacy image converter to open the file first. Once opened, you can usually use the "Save As" or "Export" function to save the bitmap data in a standard format like JPG or PNG.
What is the correct MIME type for .flt files?
The MIME type depends on the file's function. WinMerge filters are identified as text/plain, while binary versions like ImgStar images are classified as application/octet-stream. For more configuration details, visit mime-type.com.
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.
