This is a POC only.
Animated Gifs on Led matrix with very basic ftp
Create SPIFFS area using partitions.csv or Arduino IDE.
Use Winscp to upload file to the SPIFFS area. Gifs are stored in src/data/gifs
WinSCP
To force WinSCP to use the primary connection for data transfers:
In Login, go to Tools/Preferences.../Transfer/Background,
set "Maximum number of transfers at the same time" to 1.
username admin
password esp32
port 21
Use terminal to gain the IP address for ftp.
Remeber you are limited to how much SPIFFS space you have, run serial terminal on ESP32
when booting you will see something like...
