I try to download and upload file with name format like above i mention and got "553 File name not allowed. Too long." error

And i try to Up/Download with short name "IMG20220725_134430.jpg" and its work
It just my file name hit the allowed length of utf8 in this library i think?

Yes it's probably, what microcontroller and storage do you use?

I use ESP32CAM and 4GB Micro SD from Vega

I change in FtpServerKey.h
#define DEFAULT_STORAGE_TYPE_ESP32 STORAGE_SD

And in FtpServer.h
Remove <SPI.h>
Change <SD.h> to <SD_MMC.h>
Change STORAGE_MANAGER SD to STORAGE_MANAGER SD_MMC

Ah yes i use 1-bit mode by setting SD_MMC.begin("/sdcard", true);

Hi @Tri44,
I do multiple tests, and it seems that utf8 works correctly, I can't replicate it.
