About .jbf Files
JBF files are binary cache files created by PaintShop Pro.
They use the MIME type application/octet-stream and store raw data for fast access.
- Main use: Acting as a browser cache to quickly access image previews and temporary data.
- Functionality: They hold processed image or project data while you work in the application.
- Management: Files are auto-generated and maintained by PaintShop Pro. Manual editing is not advised.
- Software: Best viewed and managed within PaintShop Pro for troubleshooting or cache clearing.
These files help improve performance by temporarily caching image data during your editing sessions.
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 .jbf file and what program creates it?
JBF files are cache files created by Corel PaintShop Pro (formerly Jasc PaintShop Pro). They are specifically used to store thumbnail previews and file metadata to speed up the browsing experience within the software's "Manage" or "Browse" mode.
Can I safely delete .jbf files?
Yes, you can safely delete .jbf files, such as pspbrwse.jbf. These are temporary cache files; if you delete them, PaintShop Pro will simply regenerate a new file the next time you browse that specific folder.
How do I open a .jbf file?
You cannot open a .jbf file to view it like a standard image. It is a binary file intended only for internal use by PaintShop Pro. Because it falls under the generic MIME type application/octet-stream, attempting to open it manually will usually result in an "Open With" prompt or a display of garbled text.
Why does a pspbrwse.jbf file appear in every folder containing images?
PaintShop Pro creates a pspbrwse.jbf file in every directory you visit to cache the thumbnails for the images located there. This allows the software to display previews instantly when you return to the folder, rather than re-scanning every image file.
Can I convert a .jbf file to JPG or PNG?
No, .jbf files cannot be converted into image formats like JPG or PNG. They do not contain the full image data, but rather small thumbnails and database information. You need the original image files to view or convert the pictures.
How can I stop PaintShop Pro from creating .jbf files?
You can usually disable the creation of these cache files in the PaintShop Pro Preferences menu (often under "Cache" or "File Locations"). However, disabling this feature may cause the software to load thumbnails more slowly when you browse folders with many high-resolution images.
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.
