What is the file size limit? (NodeMCU, Esplorer)

I recently tried to host a little web interface from my ESP8266. But something kept failing until I realized that a bigger file (around 10kb) was corrupt. Well, not really corrupt, but simply incomplete. And no matter how I changed it, the file was always cut off after a certain amount of characters.

My compiled NodeMCU firmware is about 649kb in size, so there should easily be enough space. I mean my board has at least 4MB of storage (32m), so that should be plenty to store my lua, html and css files!

I used Esplorer to upload the files btw.
So what exactly is the limit here?
Is it a memory issue? A flash storage issue? An issue related to Esplorer?

Is it somehow possible to get bigger files onto my board?

edit: I should mention that uploading the init.lua file always worked even if it was around 10kb. Maybe the uploading mechanism is different for the init.lua file?

Alright, here's the long form of my comment above. My best guess is (was) that this be an issue with ESPlorer. Whenever I look at its source code I'm actually surprized how well it usually works.

At https://frightanic.com/iot/tools-ides-nodemcu/ I compiled a list of tools and IDEs for NodeMCU. I suggest you pick a different uploader and try again. The NodeMCU-Tool for example is solid and it's definitely a lot better maintained than ESPlorer is.
