Apple QuickTime Movie (QT) is a file format that Apple developed for movie clips. It is very similar to MOV in that it is a container that can hold various types of multimedia files, including 3D and virtual reality (VR). It is an older format, whereas MOV is newer.
By default, a QT file opens with QuickTime. If the QT file is Version 2.0 or earlier, then it can open with Windows Media Player, but more-recent versions will not open in this player. If unable to open a QT file with QuickTime, then use VLC media player, which works across many platforms, including mobile.
Since QT is an older format, it might be necessary to review the QuickTime support topics published by Apple support. Apple offers advice for opening a QT file, as well as help with movie playback.

Adaptive Multi-Rate (AMR) is a compressed audio file that is often used for speech coding. The AMR speech codec focuses on narrowband signals, which makes it ideal for voice recordings and radio. It is used regularly in Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS).
Since AMR files are often used on mobile phones, including for MMS messaging, most 3G mobile devices are able to open them. AMR also opens with VLC media player, QuickTime, RealPlayer, and Xine.
Other software, such as the free audio-editing software Audacity, can open AMR files. Download audacity easily at SourceForge.net. Because AMR files are heavily compressed and focused on narrowband signals, they are not suitable for music files.
