File Unzip using miniz-cpp library

Note: this does not extract tar files, only zip files.

Do we know how well this handles really large files?

Say you try to unzip a 10GB file. Does it store the whole thing in memory? (10GB memory usage)

Are there any progress indicators while it's decompressing a large file? Or does it just hang until it returns?

Hmm. This will require looking deeper into the C API. The C++ wrapper can't do what you're asking. I'll look into it.

This can potentially get really intrusive depending on how the library is currently written. We'd also need to design an API to expose the progress.

What I envision is that in the table showing all the resources, when the user click Download, it will asynchronously start downloading and decompressing without locking the UI. Then we show the % complete or a progress bar on that row in the table. So there would be a background thread that manages the download(s). If we leave and re-enter the panel, the progress will still show the progress.

Most likely is that we inject a callback into the unzip routine that will be periodically called so we can update the UI with the % completed. This may need to go hand-in-hand with splitting up a large file so we don't hold the entire thing in memory.

IOW, a lot of investigation to be done.
