About ASF Format Advanced Systems Format (formerly Advanced Streaming Format, Active Streaming Format) is Microsoft's proprietary digital audio/digital video container format, especially meant for streaming media. ASF is part of the Windows Media framework. ASF is based on serialized objects which are essentially byte sequences identified by a GUID marker. The format does not specify how (i.e. with which codec) the video or audio should be encoded; it just specifies the structure of the video/audio stream. This is similar to the function performed by the QuickTime, AVI, or Ogg container formats. One of the objectives of ASF was to support playback from digital media servers, HTTP servers, and local storage devices such as hard disk drives. The most common file types contained within an ASF file are Windows Media Audio (WMA) and Windows Media Video (WMV). Note that the file extension abbreviations are different from the codecs which have the same name. Files containing only WMA audio can be named using a .WMA extension, and files of audio and video content may have the extension.WMV. Both may use the .ASF extension if desired. We both know ASF is very important for us, but what should we do if ASF files are lost? Take it easy, all we need is just media files recovery software. So, let's check out the reasons of ASF files loss. Reasons of ASF Files Loss • 'Format error', 'write error', 'read error', 'unknown error' (with the temporary freeze in the screen). • The request could not be performed because of an I/O device error. • There might be a problem with some data on this device or disc. • 'memory card error' or ' card cannot be used' • 'please insert disk to the drive' or 'no files found' • USB drive not recognized These error messages may be warnings of the corruption of data. Logical damage (drive is recognized, but video is not accessible) and physical damage (no recognition of drive, normally caused by power interruption or electrostatic discharge) are major reasons for the loss, damage or formatting of the ASFfiles.
