Extra Characters in Image/Video Names

[The Papaw]

About once a year, I go though my collections and try to update all the media data. I download new data for everything, resize everything, combine with my older custom stuff, etc..

I am noticing that I have gotten tons of images that have extra characters add to the name. For example, Dragon Lore should be downloaded as Dragon Lore-01.ext, but I got "Dragon Lore.1dd8e7a7-1205-48dd-9a8f-13f6ea406c08-01". And many times I got multiple copies of each one with the extra characters being changed up, but they are all identical image. Sometimes 4 or 5 of them per game. I am going to have 1000's of these to find, rename and delete if I wish to get rid of them.

Can anyone explain to me here what is going on with this, why it happens and if there is anything I can do to prevent it?

 

UPDATED Info:

After spending hours going through some of this, I think am noticing a pattern. It seems that when it happens, it is happening for all the artwork for that particular game. An example is Tetris in the Arcade platform. It happens to the all the artwork for the game, Advertisement Flyer - Front, Banner, Box - 3D, Box - Front, Clear Logo, etc..

I have also noticed this still using Tetris from the Arcade platform as an example. Here are the 6 files it downloaded (keep in mind, I started with empty directories):

If it downloads 6 files into any media folder, such as the Fanart - Background folder, It means I am getting 6 files in every other folder that has an image. Say this was the Fanart - Background, I will also get 6 ClearLogos, 6 Box - Front, 6 Box3d, etc.  

All 6 of them in every folder will have matching extra characters that I hightlighted in red. Most of them only have 2-3 but some have 10+.
