+# esp8266FTPServer
+Simple FTP Server for using esp8266/esp32 SPIFFs
+
+Now should support esp32!!!  
+
+I've modified a FTP server from arduino/wifi shield to work with esp8266....
+
+This allows you to FTP into your esp8266 and access/modify the spiffs folder/data...it only allows one ftp connection at a time....very simple for now...
+
+I've tested it with Filezilla, and the basics work (upload/download/rename/delete). There's no create/modify directory support(no directory support in SPIFFS yet).
+
+You need to setup Filezilla(or other client) to only allow 1 connection..
+To force FileZilla to use the primary connection for data transfers:
+Go to File/Site Manager then select your site.
+In Transfer Settings, check "Limit number of simultaneous connections" and set the maximum to 1
+
+only supports Passive ftp mode....
+
+It does NOT support any encryption, so you'll have to disable any form of encryption...
+
+feel free to try it out (sample provided)....unzip into your arduino library directory (and restart arduino ide).

+this is the original project on github I worked from: https://github.com/gallegojm/Arduino-Ftp-Server/tree/master/FtpServer
