ASF files are very compatible with Windows, considering that they were developed by Windows. Microsoft introduced ASF files to stream files from hard disks, digital media servers, HTTP servers, and more. Similar to other video formats, ASF files do not specify any codecs, which are crucial for streaming. They specify only the video and audio structure that is streamed in Windows.
ASF files have a lot of benefits, especially in terms of seamless streaming. You can stream these video files across the RTSP Portal or MMS Portal. However, sometimes under different circumstances, these videos can become corrupted. Therefore, it's essential that you adopt the proper methods to recover ASF files. Let's explore some top ways to recover deleted or corrupted ASF files.
