Ask HN: Best Alfred for Windows?

You could try Wox for it's more expansive capabilities.

For file search you could try Everything published by Voidtools.

Does it have the same easy to pull cmd+space type thing? I really like that it's always there no need to open an application.

Wox has a preconfigured hotkey.

Everything allows you to set a preferred hotkey in the settings.

Everything is the tool I miss the most on Mac, I haven't found anything even close

Windows has its own indexing, filenames as well as content for specific types. Just press [Win] and type the filename.
