Rename file or folder not working for SD card using C/C++

[snahmad75]

Hi,

//int rc = rename("/sdcard/myfolder/", "/sdcard/myfolder2/");
int rc = rename("/sdcard/foo.txt", "/sdcard/foo2.txt");


I get rc =-1


Any idea?

I think rename file works. but it creates another copy of file.

but rename existing folder does not work.
