Contains information that the SHFileOperation function uses to perform file operations.
typedef struct _SHFILEOPSTRUCT { // shfos
HWND hwnd;
UINT wFunc;
LPCSTR pFrom;
LPCSTR pTo;
FILEOP_FLAGS fFlags;

Members
hwnd
Handle of the dialog box to use to display information about the status of the operation.
wFunc
Operation to perform. This member can be one of the following values:
FO_COPY |
Copies the files specified by pFrom to the location specified by pTo. |
FO_DELETE |
Deletes the files specified by pFrom (pTo is ignored). |
FO_MOVE |
Moves the files specified by pFrom to the location specified by pTo. |
FO_RENAME |
Renames the files specified by pFrom. |
pFrom
Pointer to a buffer that specifies one or more source file names. Multiple names must be null-separated. The list of names must be double null-terminated.
pTo
Pointer to a buffer that contains the name of the destination file or directory. The buffer can contain mutiple destination file names if the fFlags member specifies FOF_MULTIDESTFILES. Multiple names must be null-separated. The list of names must be double null-terminated.
fFlags
Flags that control the file operation. This member can be a combination of the following values:
FOF_ALLOWUNDO |
Preserves undo information, if possible. |
FOF_CONFIRMMOUSE |
Not implemented. |
FOF_FILESONLY |
Performs the operation only on files if a wildcard filename (*.*) is specified. |
FOF_MULTIDESTFILES |
Indicates that the pTo member specifies multiple destination files (one for each source file) rather than one directory where all source files are to be deposited. |
FOF_NOCONFIRMATION |
Responds with "yes to all" for any dialog box that is displayed. |
FOF_NOCONFIRMMKDIR |
Does not confirm the creation of a new directory if the operation requires one to be created. |
FOF_RENAMEONCOLLISION |
Gives the file being operated on a new name (such as "Copy #1 of...") in a move, copy, or rename operation if a file of the target name already exists. |
FOF_SILENT |
Does not display a progress dialog box. |
FOF_SIMPLEPROGRESS |
Displays a progress dialog box, but does not show the filenames. |
FOF_WANTMAPPINGHANDLE |
Fills in the hNameMappings member. The handle must be freed by using the SHFreeNameMappings function. |
fAnyOperationsAborted
Value that receives TRUE if the user aborted any file operations before they were completed or FALSE otherwise.
hNameMappings
Handle of a filename mapping object that contains an array of SHNAMEMAPPING structures. Each structure contains the old and new path names for each file that was moved, copied, or renamed. This member is used only if fFlags includes FOF_WANTMAPPINGHANDLE.
lpszProgressTitle
Pointer to a string to use as the title for a progress dialog box. This member is used only if fFlags includes FOF_SIMPLEPROGRESS.
Remarks
If pFrom or pTo are unqualified names, the current directories are taken from the global current drive and directory settings as managed by the GetCurrentDirectory and SetCurrentDirectory functions.

Example:
Copy a file to a specific path and rename it.
TCHAR* chFrom =_T("C:\\TEST\\A\\gg.txt");
TCHAR* chTo=_T("C:\\TEST\\B\\gg.txt");
TCHAR* chNewName=_T("C:\\TEST\\B\\new.txt"); SHFILEOPSTRUCT shFileOp;
ZeroMemory(&shFileOp, sizeof(SHFILEOPSTRUCT)); shFileOp.wFunc=FO_COPY;
shFileOp.pFrom=chFrom+'\0';
shFileOp.pTo=chTo+'\0';
shFileOp.fFlags=FOF_NOCONFIRMATION|FOF_SILENT; DWORD dwCopyValue= SHFileOperation (&shFileOp);
//char buffer[32];
//ltoa((long)dwCopyValue, buffer, 10); char procID[];
sprintf(procID, "%d",dwCopyValue); if(dwCopyValue!=)
{ CString strMessage;
strMessage.Format(_T("The copy operation failed.\n The error code of SHFileOperation is %d"), dwCopyValue);
MessageBox(NULL, strMessage , _T("Alert"), MB_OK);
return dwCopyValue;
} shFileOp.wFunc=FO_RENAME+'\0';
shFileOp.pFrom=chTo+'\0';
shFileOp.pTo=chNewName+'\0'; DWORD dwRenameValue= SHFileOperation (&shFileOp);
if(dwRenameValue!=)
{
MessageBox(NULL, _T("The rename operation failed, error code is ! "+dwRenameValue), _T("Alert"), MB_OK);
return dwRenameValue;
}
Possible error code:
Go to this link System Error Codes to see what each code means.
1) SHFileOperation returns 124
124 means:
ERROR_INVALID_LEVEL
124 (0x7C)
The system call level is not correct.
DE_INVALIDFILES
0x7C
The path in the source or destination or both was invalid.
Make sure the source or destination path is valid.
2) SHFileOperation returns 2
ERROR_FILE_NOT_FOUND
2 (0x2)
The system cannot find the file specified.
Make sure the file being operated exists.
