About .pbt Files
PBT files are used in two distinct ways. They can either serve as PocketBook Themes or as PowerBuilder Targets.
For PocketBook themes, PBT files use the MIME type application/octet-stream. They are in a binary format. This type of file contains data to define the appearance of PocketBook e-readers such as layouts, fonts, and color schemes.
- Use case: Customizing the look of PocketBook devices
- Function: Store theme settings in a compact binary format
- Software: Opened by PocketBook Reader apps
For PowerBuilder targets, PBT files are plain text files using the MIME type text/plain. In this context, they store configuration data, build settings, or script targets for developing applications with PowerBuilder.
- Use case: Managing build and project settings in PowerBuilder
- Function: Serve as editable configuration or target files
- Software: Accessible via the PowerBuilder IDE or any standard text editor
According to FilExt.com, the PBT extension covers both these uses, each with its specific format and application.
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.
