The Quick Way to Open Files with I00 Extension

Different software packages use different file extensions, so if you can't open the I00 file, it could be because:

  • You don't have the associated software on your computer (Winphone Phonebook is the most popular software package that uses I00 file).

  • You may have Winphone Phonebook but your computer is not configured to associate I00 files with the relevant software.

  • The file is corrupt.

If You Don't Have Winphone Phonebook

In order to open your I00 file, you will have to download Winphone Phonebook or another similar software package.

If Your Computer is Not Configured to Open I00 Files

If you have the relevant software, but your computer still won't open the software, you will have to change the file associations on Windows or Mac. Depending on your operating system, you can ensure that your computer always open I00 files using Winphone Phonebook or another program of your choice that uses I00 files.

If that still doesn't work, you can get in touch with your software developer to find out what you can do. You can contact any of these developers for more information or assistance:
