Recently, I updated OOSU10, or I think I did. I was instructed to download the update to the same location where I already had OOSU. I did, which is my Desktop, but afterwards rather than a single OOSU10 icon there were two. I thought that strange and ought not to have happened. I deleted the older icon hoping, perhaps naïvely, that was the right thing to do. Twice since updating I have run OOSU10. On both occasions it has created a file on my Desktop with a sort of blank white icon* and the file type was .cfg. On both occasions I have deleted the .cfg files. Today I googled what they were and discovered they're used to store settings so I may have been unwise to delete them.
Can anyone please explain why OOSU10 is creating these .cfg files? It has never previously done so. If it's settings that need to be retained should I move OOSU10 elsewhere? I don't want my Desktop littered with .cfg files.
*I attach a screen shot of the icon.
