Notes about the RBL file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The RBL file type is primarily associated with 'RegexBuddy' by JGsoft - Just Great Software. RegexBuddy is a companion for working with regular expressions. Create regular expressions that match exactly what you want. Understand complex regexes written by others. Test any regex on sample strings and files. RegexBuddy stores the regular expression library that you create on the Library tab, into an .RBL file.
