question about wyu files

Do we need all the wyu files that are created over different versions?

We appear to have "all to 1.3" and "all to 1.2" and "all to 1.1". Would it cause any problems to delete the last two and only add the latest one, ie "all to the latest version"?

Also are the interim versions necessary so "1.1 to 1.2" if we already have "1.1 to latest version" can we delete the other ones or are they needed in the process?

Our problem is that since the application is large <300MB the all versions are very big and take a long time to upload, download test etc - it would be better if we only needed to use a single version of the large file, so just need clarification on this please?

Yes, you can delete the old update files.

So, if you have a bunch of "* to 1.3.wyu" as well as your latest version "* to 2.0.wyu", then you can safely delete the "* to 1.3.wyu" files.

Be careful not to delete the *.wys file. That's always necessary. The name doesn't change, but the contents of the file do change with every new built update.
