Changes
V1.03
x removed all SPIFFS from ESP32 version, switched fully to LittleFS
x fixed rename+delete for ESP32+LittleFS (added "/")
V1.02
x fixed the way to select the file system by conditional defines
V1.01
+ added file name progress while uploading
x fixed error in ZIP file structure (zip.bitflags needs a flag)
V1.00
+ out of V0.9998...
+ ESP8266: LittleFS is default
+ javascript: added "msgline();"
+ javascript: added "Loading..." as a not-working-hint to show that Javascript is disabled
+ cleaning up the "/"-stuff (from SPIFF with leading "/" to LittleFS without...)
+ Warning: esp8266 2.7.4 has an error in mime::getContentType(path) for .TXT. Fix line 65 is { kTxtSuffix, kTxt },
+ review of "edit file", moved some stuff to ESPxWebFlMgrWpF.h

History
-- 2019-07-07
+ Renamed to ESPxWebFlMgr and made it work with esp32 and esp8266
+ separated file manager web page, "build script" to generate it
-- 2019-07-06
+ "Download all files" creates a zip file from all files and downloads it
+ option to set background color
- html5 fixes
-- 2019-07-03
+ Public Release on https://github.com/holgerlembke/ESP8266WebFlMgr
Things to do
?? unify file system access for SPIFFS, LittleFS and SDFS
