What is a 3GPP file?
The 3GPP file extension is functionally identical to 3GP, serving as a simplified version of the MPEG-4 Part 14 (MP4) container format. Designed by the 3rd Generation Partnership Project for GSM networks, it handles data storage for audio, video, and text (subtitles). The format adheres to ETSI 3GPP technical specifications TS 26.244, supporting variable bit rate (VBR) audio via the Adaptive Multi-Rate (AMR) codec. While less common than the three-character .3gp extension, .3gpp is fully compliant with the ISO/IEC 14496-12 standard.
How to open a 3GPP file
Opening a 3GPP file requires software capable of parsing the ISO base media file structure and decoding H.263/H.264 video alongside AMR audio. Native support exists in standard Android video players. For Windows and macOS users, if the default media players (Movies & TV, QuickTime) encounter playback errors, the VLC media player is the industry-standard solution for rendering these mobile-specific archives.

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.
