What is a 3GP file?
The 3GP format is a multimedia container defined by the 3rd Generation Partnership Project (3GPP) primarily for 3G UMTS multimedia services on GSM-based mobile networks. Ideally suited for mobile bandwidth limitations, it encapsulates video streams encoded in MPEG-4 Part 2, H.263, or H.264 (MPEG-4 AVC) and audio in AMR-NB, AMR-WB, or AAC formats. The structure is based on the ISO base media file format (MPEG-4 Part 12), prioritizing high compression ratios over high-fidelity playback to facilitate Multimedia Messaging Service (MMS) transmission.
How to open a 3GP file
Most modern mobile operating systems (Android, iOS) handle 3GP natively. On desktop systems, Microsoft Windows Media Player and Apple QuickTime provide varying degrees of support depending on the specific video codec used within the container. If native players fail to render the AMR audio track, users should utilize the VLC media player or MPlayer, which contain built-in libraries for decoding 3GPP-compliant streams.

What is a WMA file?
Windows Media Audio (WMA) refers to a series of audio codecs and their corresponding Microsoft container format, designed as a competitor to MP3 and RealAudio. The standard WMA codec is lossy, but the format family includes WMA Lossless, WMA Pro (multichannel), and WMA Voice. It utilizes the Advanced Systems Format (ASF) container structure and supports digital rights management (DRM), which historically restricted playback to authorized Windows devices.
How to open a WMA file
WMA files are native to the Windows ecosystem and open by default in Windows Media Player and Movies & TV. macOS users require third-party components like Flip4Mac (legacy) or universal players such as VLC Media Player and Elmedia Player to decode the stream. Android and Linux support is generally provided via VLC or by installing ffmpeg-based media libraries.
