With DIM, there are special files that must be in the zip. I don't want to convert the zips to DIM installable zips. I just want to install them.

Ok, so looks like I'll start writing an app that does this. Let's get some requirements. Ability to specify more than one content folder is a must. So for each content folder, you'll create a zip store folder. You dump your zips in the respective folder and run the app and it'll put the files in the proper content folder.

Next, I need a list of folders to look for in the zip that will be copied to the content folder since each zip has a different nesting level (ex Content)

By default, these will be copied (user can configure this): runtime, data, people, presets, shader presets, environments

Ignore folders: documentation

Any unrecognized folders will prompt the user whether to copy to content folder or ignore.

Will need conflict resolution options when overwriting files.

A list of what's been installed and ability to uninstall (and restore any overwritten files). Log file.

I think that should be a good start. If you have ideas or features you want to see, let me know.
