AdSense provides a personalized ads.txt file that you can download from your account. The personalized ads.txt file includes your publisher ID. Your publisher ID must be included and formatted correctly for your ads.txt file to be verified.
Save the file on your PC in the default download location. After Internet Explorer runs a security scan and finishes downloading the file, you can choose to open the file, the folder it's stored in, or view it in Download Manager.
Download Manager keeps track of pictures, documents, and other files you download from the web. Files you've downloaded are automatically saved in the Downloads folder. This folder is usually located on the drive where Windows is installed (for example, C:\\users\\your name\\downloads). You can always move downloads from the Downloads folder to other places on your PC.
To view files you've downloaded while using Internet Explorer, open Internet Explorer, select the Tools button, and then select View downloads. You'll be able to see what you've downloaded from the web, where these items are stored on your PC, and choose actions to take on your downloads.
When you download a file, Internet Explorer checks for clues that the download is malicious or potentially harmful to your PC. If Internet Explorer identifies a download as suspicious, you'll be notified so you can decide whether or not to save, run, or open the file. Not all files you're warned about are malicious, but it's important to make sure you trust the site you're downloading from, and that you really want to download the file.
If you see a security warning that tells you the publisher of this program couldn't be verified, this means that Internet Explorer doesn't recognize the site or organization asking you to download the file. Make sure you recognize and trust the publisher before you save or open the download.
If the file has a digital signature, make sure that the signature is valid and the file is from a trusted location. To see the digital signature, select the publisher link in the security warning dialog box that opens when you first download the file.
Advanced Systems Format (.asf)The Advanced Systems Format (ASF) is the preferred Windows Media file format. With Windows Media Player, if the appropriate codecs are installed on your computer, you can play audio content, video content, or both, that is compressed with a wide variety of codecs and that is stored in an .asf file. Additionally, you can stream audio and video content with Windows Media Services, or you can package that content with Windows Media Rights Manager.ASF is an extensible file format that stores synchronized multimedia data. It supports data delivery over a wide variety of networks and protocols. It is also suitable for local playback. ASF supports advanced multimedia capabilities including extensible media types, component download, scalable media types, author-specified stream prioritization, multiple language support, and extensive bibliographic capabilities that include document and content management.Typically, ASF files that contain audio content that is compressed with the Windows Media Audio (WMA) codec use the .wma extension. Similarly, ASF files that contain audio content, video content, or both, that is compressed with Windows Media Audio (WMA) and Windows Media Video (WMV) codecs use the .wmv extension. Finally, content that is compressed with any other codec use the generic .asf extension. For more information about ASF, visit the following Microsoft Web site:
Windows Media Audio (.wma)Windows Media Audio (.wma) files are Advanced Systems Format (.asf) files that include audio that is compressed with the Windows Media Audio (WMA) codec. By using a separate extension, users can install multiple players on their computer and associate certain players with the .wma extension for playback of audio-only sources.
Windows Media Video (.wmv, .wm)Windows Media Video (.wmv) files are Advanced Systems Format (.asf) files that include audio, video, or both compressed with Windows Media Audio (WMA) and Windows Media Video (WMV) codecs. By using a separate extension, you can install multiple players on your computer and associate certain players with the .wmv extension for playback of audio and video sources.
Advanced Stream Redirector (.asx)Advanced Stream Redirector (.asx) files, also known as Windows Media Metafiles, are text files that provide information about a file stream and its presentation. ASX files go beyond the simple task of defining playlists to provide Windows Media Player with information about how to present particular media items of the playlist.Windows Media Metafiles are based on XML syntax and can be encoded in either ANSI or UNICODE (UTF-8) format. They are made up of various elements with their associated tags and attributes. Each element in a Windows Media metafile defines a particular setting or action in Windows Media Player.ASX files can point to any media file type that Windows Media Player recognizes and supports.For more information about Windows Media Metafiles, visit the following Microsoft Web site:
Windows Media Player Playlist (.wpl)Windows Media Player Playlist (.wpl) files are client-side playlists that are written in a proprietary format. Microsoft introduced this file format in Windows Media Player 9 Series. The .wpl format can create dynamic playlists, whereas .asx and .m3u formats cannot. In Windows Media Player 9 Series, the auto playlist feature uses the .wpl format. The .wpl format is the default file format used for playlists that you save in Windows Media Player 9 Series.
In Microsoft Windows XP Media Center Edition, Microsoft introduced the *.dvr-ms file format for storing recorded TV content. Similar to *.asf files, *.dvr-ms file enhancements permit key Personal Video Recorder (PVR) functionality, including time-shifting, live pause, and simultaneous record and playback. Video contained in a *.dvr-ms file is encoded as MPEG-2 video stream, and the audio contained in the *.dvr-ms file is encoded as MPEG-1 Layer II audio stream.To play back unprotected *.dvr-ms files on Windows XP-based computers, you must have the following software and hardware components:
Windows Media Download (WMD) packages combine Windows Media Player skin borders, playlist information, and multimedia content in a single downloadable file that uses a .wmd extension. A .wmd package can include a whole album of music videos that also displays advertising in the form of graphical branding and links to an online music retailer Web site.To download a .wmd package from a Web site, click the link to the package. When the package is downloaded to your computer, Windows Media Player automatically extracts the files that are contained in the package, adds the playlists in the package, adds the content to Media Library, displays the border skin in theNow Playing pane of Windows Media Player (in full mode), and then plays the first item in the playlist. For more information about .wmd files, visit the following Microsoft Web site:
Audio Video Interleave (AVI) is a special case of Resource Interchange File Format (RIFF). AVI is defined by Microsoft. The .avi file format is the most common format for audio and video data on a computer.Audio content or video content that is compressed with a wide variety of codecs can be stored in an .avi file and played in Windows Media Player, if the appropriate codecs are installed on the computer. Video codecs that are frequently used in .avi files include the following codecs:
MPEG-1 (.mpeg, .mpg, .m1v)This standard permits the coding of progressive video at a transmission rate of about 1.5 million bits per second (bps). This file format was designed specifically for use with Video-CD and CD-i media. The most common implementations of the MPEG-1 standard provides a video resolution of 352x240 at 30 frames per second (fps). When you use this standard, you receive a video that is slightly lower-quality than typical VCR videos.Files that use the .m1v extension typically are MPEG-1 elementary streams that contain only video information. Files that use .mpg or .mpeg extensions typically are MPEG-1 system streams that contain MPEG-1-encoded video and MPEG-1 Layer II (MP2)-encoded audio.However, MPEG-1 system streams do not exclusively use the .mpg and .mpeg extensions. MPEG-2 program streams also frequently use .mpg and .mpeg file extensions, but they contain MPEG-2-encoded video. Because Microsoft Windows operating systems provide only an MPEG-1 video decoder, Windows Media Player cannot play MPEG-2 program streams without an additional MPEG-2 video decoder (also known as a DVD decoder pack) installed. For more information about purchasing DVD decoder packs, visit the following Microsoft Web site:
Windows uses the Wave Form Audio (WAV) file format to store sounds as waveforms. One minute of Pulse Code Modulation (PCM)-encoded sound can occupy as little as 644 kilobytes (KB) or as much as 27 megabytes (MB) of storage. This size of the storage space depends on the sampling frequency, the type of sound (mono or stereo), and the number of bits that are used for the sample.Similar to the AVI and ASF format, WAV is only a file container. Audio content that is compressed with a wide variety of codecs and that is stored in a .wav file can be played back in Windows Media Player if the appropriate codecs are installed on the computer. The most common audio codecs that are used in .wav files include Microsoft Adaptive Differential Pulse Code Modulation (MS ADPCM) and uncompressed Pulse Code Modulation (PCM).
CD Audio (.cda) tracks are audio files that are stored on CD media. You can play .cda files only from a CD-ROM. As a result, a sample file cannot be included in this article for you to play. To test a .cda file, either try to play a different .cda file from your CD-ROM or try to play a .cda file from a different CD-ROM. The .cda files are representations of CD audio tracks and
