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.

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