Gary, Hi, for the benefit of everyone I'll post it the answer I sent you via e-mail.

The time stamps are added to the file name in order to facilitate going through different versions based on the time when the file was saved. You may end up having the same time stamp for the same file in different locations but not the same file in the same location. In addition, you can also turn auto save for past versions on to have the time stamp automatically added at a fixed interval you can set which can be between 1 to 60 minutes. 
If you’re also referring to a potential hash collisions - this isn’t the case here. 

Hope this helps. 
Best regards,
Liran

Thomas Roberts, Hi, the add-in is also available for Word and Excel. Previous round here at Giveawayoftheday, Word was the free give away. Now, I decided to release PowerPoint. On the SOS Click site you can find the bundle which comes at the price of two instead of three add-ins. I may release eventually only one bundle containing the three installer files for Word, Excel and PowerPoint instead of offering separate add-ins and the bundle although my sales have shown Office users do like the option of getting only one add-in for a specific Office application and not everything bundled together so it really depends.

All the best

Thomas Roberts, You Can. Look at the video https://www.sos-click.com/product-page/sos

Liran,
Nope! Many people like it when add-ins (add-in) go at once not only for all office releases from Microsoft, but for other office products. There are a lot of such office products, semi-paid, and paid.

Dima, That's correct which is why I'm considering releasing the all-in-one bundle without offering separate add-ins although my sale records do show people prefer to buy only what they need, so it's not something crystal-clear. The second point you make is true for certain products but I've come across separate add-ins for separate Office applications. It depends on the vendor and the pricing of the software in question, making them both cheaper and thus more affordable as well as giving the user a more granular choice.

TK, Dear TK. If there’s demand I’ll look into porting it to Publisher as well as other Office apps. For a start, I wanted to begin with the ones people use the most. I was also asked the same about Project and Visio probably falls into the same category too. Will see how things develop. Many thanks for your interest!
