What is a .jbf file?
A .jbf file is a PaintShop Pro Browser Cache File. This is a system or support file. Your computer uses it in the background — it isn't a document.
How to open a .jbf file
- Usually nothing. These files are read by the operating system or an application, not by you.
- If it's plain text (settings, logs), a text editor will show its contents safely.
The registry records this extension against PaintShop Pro Browser Cache File, so software from that family is the most likely match.
How to convert a .jbf file
- System files shouldn't be converted. If a program is complaining about one, reinstalling that program is the usual fix.
