download does not work

[fred9999]

Thank you for the File Manager. I like its minimalistic design and bare essential feature list very much.

I'm trying to get the ESP32basicwsagzip.ino work on ESP32 (ESP32 Dev Module 4MB, LittleFS)

Features that work are edit, rename, upload, delete.

Download does not work. Browser goes to the address 192.168.1.44:8080/c?dwn=data.txt for file "data.txt", but nothing happens, empty webpage is shown.
Clicking on folder, browser goes to the address 192.168.1.44:8080/c?dwn=folder but does not represent anything

Download all files downloads alles.zip file
When I try to unzip it with IZArc it complains "bad zip header found". If I unzip it anyway it contains only the first file alphabetically from LittleFS file system, but the content is empty, 0 Bytes.

The behavior is the same on Firefox and Google Chrome.

Do you have any suggestions how to debug this situation and get your script working?

Thank you in advance.

Sorry, currently I have no idea of a fix.

Hi Holger,

OK I see. Thank you for the reply anyway!

LittleFS seems to be a bit tricky / buggy on ESP32. For example in my tests the "append to file" speed is about 10 times slower that with SPIFFS (about 60ms vs. 5ms). I have posted the issue on a couple of forums but no fix / advice so far.

Kind regards,
Fred

I have exactly the same problem. I solved it! Edit the file \libraries\ESPxWebFlMgr-master\src\ESPxWebFlMgrWp.h
...
function downloadfile(filename) {
window.location.href = "/c?dwn=/" + filename;
}
...
