Is there a way to access the phone filesystem from computer, wireless?

Known solutions: * USB Mass Storage (sadly, mostly deprecated on Android 4, 5, etc.). * MTP, and I know its benefits (a lot) and its weaknesses (browsing on a MTP drive with Windows Explorer has poor integration of usual features: try to right click on a file on a MTP drive, you don't have the usual UI things like Open with etc.) * Samba * FTP server solutions (good solution, but 1) how to use this if I'm on the road, with no Wifi router like at home? then I cannot link computer phone? 2) it seems that [such an app](https://play.google.com/store/apps/details?id=com.medhaapps.wififtpserver.pro) doesn't offer access to external sd card) * AirDroid, etc. But with all these methods, **you don't really have access on your computer to the phone's filesystem like if it was a local folder**. Question: **Is there a solution that makes it possible to browse the phone's filesystem as if it was a computer local folder, easily?**
