Notes about the IBF 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 IBF file type is primarily associated with 'Instant Backup' by Towodo Software.
Instant Backup lets you backup your important data fast and easy from/to a Network, CD-RW, ZIP, JAZ or any other drive.
The backed up files are stored separately, with the same hierarchy as in the source.
These files can sometimes be opened using WinRAR.
