Hi ,
How do you get the size of an open file?
How do you copy a file?
I didn't find an api to get the size of a file.
For example, if I want to copy a file and rename it to another file, what should I do?
Thanks!

Hi @111llll111,
you can use the APIs:
UINT fx_directory_first_full_entry_find(FX_MEDIA *media_ptr, CHAR *directory_name,
UINT *attributes, ULONG *size,
UINT *year, UINT *month, UINT *day,
UINT *hour, UINT *minute, UINT *second);
UINT fx_directory_next_full_entry_find(FX_MEDIA *media_ptr, CHAR *directory_name,
UINT *attributes, ULONG *size,
UINT *year,UINT *month, UINT *day,
UINT *hour, UINT *minute, UINT *second);

There is no straight way to copy file as far as I know. (To just rename there is API fx_file_rename
)
To know file size you can open the file with fx_file_open
and then read the fx_file_current_file_size
attribute from the file_ptr

The FX_FILE
struct has the fx_file_current_file_size
so I can open two files at the same time, reading and writing at the same time is equivalent to copying.
