To Know file type

Recently started learning Audacity. I have a sound file in VLC Player. I don’t know what file type is it. I would like to
insert it to Audacity and use it as MP3. Without knowing file type I tried to just drag it from VLC player to Audacity. Once I drag
that is not going to Audacity. How to bring it into Audacity ?
There are around 15 separate files. From each file I have to remove some voice from the beginning. How to do this please.

I have saved in laptop some sound files as mp3.
Out of that 2 files are .partial
I mean after the file name there is .partial in the place of extension name.
How to change this to mp3 ?
What does it mean by .partial and how that name is coming ?

I suggest you enable Windows to show file extensions, which are the three or four letters after the file name. The extension tells Windows what the file type is, and then it knows what applications (programs) can open that file type. See Show extensions for known file types in Windows.

I suggest you install FFmpeg then Audacity can import most types of file. See for instructions.

If you mean to delete all that audio (voice and everything else), drag-select in the waves then press Delete on your computer keyboard.

If you mean remove the voice from the audio and leave the rest of the audio there without deleting it, see Tutorial - Vocal Removal and Isolation - Audacity Manual.


See above. Changing the extension of the file name does not convert it to that file type.

The file may not even be complete. Some application that downloaded the file may have given it “.partial” extension for that reason. To find out what file type the file really is, download “MediaInfo” from Get the version without installer, because the installer may have malware or adware.

If MediaInfo cannot open the file, then it is corrupted and probably not usable. If it is a WAV file, Audacity “might” be able to import it by using File > Import > Raw Data… , but even if it is a WAV that won’t work properly unless you know all the details of the file already, like encoding and byte order.
