What is the difference between ASF and WMV files?

Both are valid file extensions for Windows Media files. The .asf extension is used when the file content is formatted as Advanced Systems Format (ASF) and compressed using any codec. If the content is compressed with the Windows Media Video codec, the .wmv file name extension is used.

Are ASF files safe?

Popular transfer files such as .MP3, .ASF and .JPG are so far free of native malware. But this does not mean that they are always guaranteed to be safe. Windows media files, .ASF (Advanced Systems Format), can contain audio and video data, but also other binary files. This could become a potential new threat area in the future.
