Hello Takahiro I hope you have an idea what might be missing in the FAT file system support for long names.
When running the SCT I saw this error for the GetInfo functional test: GetInfo() Basic Test - checkpoint3 -- PASS E4F4F6A2-7538-4C79-AA3C-67184EC70E16 /home/supven01/work/sct_workspace/edk2/SctPkg/TestCase/UEFI/EFI/Protocol/SimpleFileSystem/BlackBoxTest/SimpleFileSystemBBTestFunction.c:8607: SystemInfo->Size - 18, BufferSize - 18, Tpl - 8 EFI: Entry efi_file_open(000000007ef8c250, 000000007edeb0c0, "BBTestGetInfoBasicTestCheckpoint3_File_0", 8000000000000003, 0) Error: allocating new dir entry EFI: Exit: efi_file_open: 14 EFI: Entry efi_file_open(000000007ef8c250, 000000007edeb0c8, "BBTestGetInfoBasicTestCheckpoint3_File_1", 8000000000000003, 0) Error: allocating new dir entry In the EFI shell output to a file with a long name sometimes fails (depending on the history of the volume). FS0:\> echo a > foo FS0:\> echo a > abcdefgh.ijk FS0:\> echo a > abcdefgh.ijkl ** Unable to write file /abcdefgh.ijkl ** FS0:\> Up to now the SCT test is the only thing that fails reproducibly.
