What is a .TT2 file?
A .TT2 file is a type of temporary file used during the installation of Microsoft Office software, including versions like Microsoft Office 2013 and Microsoft Office 365, as well as Microsoft OneNote. This file is specifically created to temporarily store information about TrueType Font (.TTF) files that are being installed along with the Office suite.
When you download and install Microsoft Office, the installation is handled by a utility called the Microsoft Office Installer. This installer is responsible for setting up various components of the Office suite such as Word, Excel, PowerPoint, and OneNote on your computer. During this process, the installer creates temporary files, including .TT2 files, to manage and organize data effectively. These files temporarily hold data about the .TTF files that are needed for the Office programs.
Typically, once the installation process is complete, the installer should automatically delete all temporary files, including the .TT2 files. However, due to a known bug in the Microsoft Office Installer, these .TT2 files might not be deleted as intended. Instead, they can be left behind on your computer, usually in the C:\ drive. It's important to note that the presence of these leftover .TT2 files does not affect the functionality or installation of the TrueType Fonts or the Office programs themselves; the necessary .TTF files are still correctly installed in their designated locations.
Since .TT2 files are not meant to be opened and are merely temporary files containing duplicated data from .TTF files, you can safely delete them if you find them remaining after an installation. Alternatively, restarting Windows might also help in automatically removing these leftover .TT2 files.
In summary, .TT2 files are temporary files created by the Microsoft Office Installer to handle font data during the installation of Office software. They are not intended to be opened directly and can be deleted if found after the installation process.
