Cannot upload more than 3 files

[pasz1972]

Somehow I cannot upload more than 3 files. After the 3rd file, a file is 0 bytes in size and the upload functionality is not able to receive more. Even after deleting files, the upload is not working anymore.

Waht ESP do you have and with what settings did you compile? You need at least 1 mb flash to store te firmware and the HTML files

reflash.. first upload root.html.. oben this file in browser. there you will see how much space is left.

@demlak true but only if you flash your ESP with the correct flash size. I had the same thing, I flashed my esp-201 on 512kB but it has 1mb flash so the root.html file only sees 512KB (2 files 99% full), I changed the flash size in IDE to 1mb and flashed it again then it showed 35% full with all files.

There is an example in IDE to read out the actual flash size of you ESP CheckFlashConfig

/* 
 ESP8266 CheckFlashConfig by Markus Sattler

 This sketch tests if the EEPROM settings of the IDE match to the Hardware

 */

void setup(void) {
    Serial.begin(115200);
}

void loop() {

    uint32_t realSize = ESP.getFlashChipRealSize();
    uint32_t ideSize = ESP.getFlashChipSize();
    FlashMode_t ideMode = ESP.getFlashChipMode();

    Serial.printf("Flash real id:   %08X\n", ESP.getFlashChipId());
    Serial.printf("Flash real size: %u\n\n", realSize);

    Serial.printf("Flash ide  size: %u\n", ideSize);
    Serial.printf("Flash ide speed: %u\n", ESP.getFlashChipSpeed());
    Serial.printf("Flash ide mode:  %s\n", (ideMode == FM_QIO ? "QIO" : ideMode == FM_QOUT ? "QOUT" : ideMode == FM_DIO ? "DIO" : ideMode == FM_DOUT ? "DOUT" : "UNKNOWN"));

    if(ideSize != realSize) {
        Serial.println("Flash Chip configuration wrong!\n");
    } else {
        Serial.println("Flash Chip configuration ok.\n");
    }

    delay(5000);
}

Solved. Had to select 4M (1M SPIFFS) for this board : http://cdn3.bigcommerce.com/s-vt19phz/products/2065/images/5309/ESP8266_ESP_12_Full_Evaluation_Board_from_Tronixlabs_Australia_3__92271.1421807409.1280.1280.png?c=2
