Sara

Hello Sara, I am working with Arduino IDE Ver: 1.8.12.
I have an older PC that runs WIN 8.1, which can not be upgraded?

Hi.
I think you can use Arduino 2.0 on thar computer. You have to try it.
 
But, don’t you see the Filesystem Uploader command in the tools menu?
What options appear in your Tools menu? Can you show me a printscreen?
 
Regards,
Sara

Hello Sara, excuse my delay in returning your response, lots of things going on in our household!
No, my old PC can not upgrade to WIN 10, stuck with WIN 8.1??
Any way, the issue I am seeing happens when about I would be uploading a file with LittleFS, as the tutirial RNT Tutorial – ESP32: Uploae FIless tp L:ittleFS using Arduino IDE I noted a possible issue with the step to add esp32fs.jar to the Tool folder:

After I have selected the Tools menu,
I selected the ESP32 Sketch Data Upload tab;
Instead of opening the screen above, the sketch imediately returns the following message;
[SPIFFS] upload : C:\Users\Paul\AppData\Local\Temp\arduino_build_377234/Filesystem_uploader.spiffs.bin

Why didn’t box did not appear to select LittleFS, instead it simply used SPIFFS process? 

I would attache a screenshot, however I don’t see how to provide the dementions field input to use the forum’s Inset,edit Image () process?

Hi.
Are you using this release file? https://github.com/lorol/arduino-esp32fs-plugin/releases ?
Which release file are you using?
Regards,
Sar

I upgraded to the latest arduino-esp32-plugin/releases dated 04 Feb 02:54; I assume the date refers to 2025?
No change on seeing this screen when selecting the following;
After I have selected the Tools menu,
I selected the ESP32 Sketch Data Upload tab;
 

Also, now this is the results on the Serial Monitor:
16:59:00.956 -> Filesystem_uploader.ino
16:59:00.956 -> 02/17/2025
16:59:00.956 -> E (9) esp_littlefs: ./components/esp_littlefs/src/littlefs/lfs.c:1367:error: Corrupted dir pair at {0x0, 0x1}
16:59:00.956 ->

16:59:00.990 -> E (14) esp_littlefs: Failed to initialize LittleFS
16:59:00.990 -> An Error has occurred while mounting SPIFFS
Is there a process to allow to attach screehshots?

Hi.
It’s difficult to tell what might be wrong.
I suggest trying with a new installation of Arduino IDE. It sseems you may have some folders messe up or the littleFS file corrupted.
