I have been playing with the trial and have an observation. I have ended up with 4 or 5 versions during my testing.
In the update folder I have all to 1.0all to 1.2all to 1.3 etc
1.0 to 1.11.0 to 1.2 1.0 to 1.3
1.1 to 1.21.1 to 1.3
1.2 to 1.3 and so on
If I remove 1.0 as I know that nobody is using it any more could wyBuild remove some of these files or does it need to keep them do keep the versioning working?
You can safely delete the * to 1.1 & * to 1.2 files. The reason is that they are of no use anymore. Only * to [Latest version] (in your case "* to 1.3") will be used by wyUpdate.
Also when i create 1.0 of my app i drop the 1.0 exe into my application folder
I then later create 1.1 and drop 1.1 exe into my application folder
Does wyBuild examine these files once only or continually reference these files? ie do i have to keep all the previous exe versions of my app or can i delete them once wyBuild has created the patch?
wyBuild requires the files to be kept around. wyBuild only references these files from disk. Then when it builds your updates it scans the differences between the files.
