Hi,
I'm usingh SHFileOperation function to copy and remove folder.
this function Returns zero if successful, or nonzero otherwise.

if it returns nonzero, then how I know  that what are the actual problem.

I'm getting nonzero returns value when their is no space in harddisk. in this condition I want to display the message "No disk space"

so, how I know the real problem on nonzero returns.

i don't think there is a error function specific for shell functions ... your best bet would be to try GetLastError

Why not use CFile which throws an exception in case of an error and you can handle accordingly. Using SHFileOperation() you must validate all the inputs before carrying out the operation.

Oops i am sorry I did not read MSDN clearly though..CFile works only for files. bkfirebird is right. Use GetLastError() to find if any error has occurred. Also make a check for fAnyOperationsAborted flag after the operation. As such the function just returns boolean value. Its a known issue of SHFileOperation() API.

Best way to do is write a recursive function which does file copy recursively.
