Filter for filepicker

[gilphilbert]

The filepicker is fantastic - just made my life infinitely easier!

One question though: I've read through the code quickly and it seems the answer is no, but does the filePicker have a filter? For example, could I allow it to show only files with a specific extension (*.txt) or fitting a specific name (*log.txt)?

If this is the filePickMenu as used in SDCard.ino or SdFat.ino (example sketches) then I would be very interested to know how you got it to work because it doesn't for me. Thanks very much in advance.

Can you share some code you've tried? I'm using this with U8g2 and custom input on an ESP32 with an SD card on a shared SPI bus using SD.h (code from SDCard.ino) - and I've had no issues at all.

Here is SdFat01.ino as modified. I am using it with a basic Uno clone and an SD card - no u8g2 here at all in this instance - input and output via serial monitor only - and it doesn't work for me. I get garbage characters where the SUBMENU line should be, and the program crashes and restarts when any key is pressed. This is with pins 10, 11, 12 & 13 used for SPI + 5V and GND connections and USB as the basic power and PC connection. The same hardware configuration works perfectly with the standard SdFat.h library examples.

I have switched from a Mega to an ESP8266, to avoid the AVR Progmem memory issues. But am now getting loads of compile errors about type File (from SdFat.h) not being recognized.
