What is a(n) TOC file?

TOC (Eudora Table Of Contents) files are used by the Eudora e-mail client for Novell NetWare, Mac OS, and Windows operating systems. It stores a summary of messages which have been stored on the local disk so that the user can quickly access past emails without having to search through a long list. TOC files store key pieces of information about each email, such as the sender's address, subject line, time and date sent, and size.

TOC files have a .toc extension and are typically stored with their corresponding inbox files; .mbx for Windows and Mac OS platforms and .inb for the NetWare platform. The file format is binary and is not readable using text editors. Some versions of Eudora allow users to manually create TOC files by pointing the software to specific inbox folders.

How to open TOC file?

There could be multiple reasons for which the system does not support given file. In the case of TOC extension, it is probable that none of the installed programs support given file type. Therefore, user should undertake the following steps

Step 1: Install a program that supports TOC files

If an application that supports TOC files is installed on user’s system, but is not used to open such files by default, right-click on the file icon and choose "Open with" option from the menu. Next, select the proper application and check the "Always use the selected application to open this kind of files" box. The system will store this information in its registry and use the selected program to open files with TOC extension by default.

  • Structure of given TOC file could be corrupted and as such the program is not able to open the file
  • Storage medium on which the file was stored is damaged
  • It is important to ascertain that the icon representing given file is not a shortcut a related TOC file no longer present in the location to which the shortcut points
