 Here is Rohit who is a junior under Mohan. Mohan is a busy executive, who is now called to make a presentation.  He delegates the work to Rohit, who dutifully prepares a PPT and then attaches it to an email (or Slack or Teams or what-have-you). It reaches Mohan, who downloads it and immediately starts working on refining it. Then he saves the new file in the right location on his computer (and not really where the email/Slack/... had downloaded it).  Here is Rohit who is a junior under Mohan.

-So there are actually four different versions. Now some may say, all four are the same. Yes, to begin with all the four versions would likely to be the same. But it will not remain that way for long (usually). For e.g. Rohit may idly keep changing the PPT (V1) after he has sent it as an attachment to Mohan. Or Mohan, in his eagerness, modified the one at the default location where the attachment was downloaded (V3) and of course, the final place (V4) also gets modified. +In short, there are actually four different variations.

 So let's come back to the desperate situation Mohan is facing: His laptop is not working and he needs to present the PPT. So he calls up Rohit, and asks him to send over the PPT file. Rohit; again in desperation, attaches the V1 file (instead of the one that was already in the previous sent-email i.e. V2)  So let's come back to the desperate situation Mohan is facing: His laptop is not working and he needs to present the PPT.

 +**Difference between a //variation// and a //version//**\\ 
 +In the above document, the word "variation" means a file which originally was the exactly the same as some other file, but then someone made some changes to it. The "variation" will be a separate file.  
 + 
 +A "version"; on the other hand, is the same original file which was consciously edited and overwritten the original. So one can have multiple "variation" files, but at any point in time there is only one "version" file, and that is always the original.
