If you select a single file when using OFN_ALLOWMULTISELECT, the nFileExtension field contains the offset to the extension. If you select multiple files, the nFileExtension field contains 0.

This way you can determine if a single file was selected, and just read/copy the buffer pointed to by the lpstrFile field (which will be a single null terminated string containing the full path and filename including extension)

or if multiple files where selected, then you parse the buffer pointed to by the lpstrFile field, using nFileOffset to read/copy the folder first (using lstrcpyn for example and specifying length to read as the nFileOffset value) and then read/copy from nFileOffset to next null which is file1 string, add the file string length +1 to get next position to read/copy next file string etc till you reach a file string that starts with null - which is the double null for end of all files (as the last string before this is null terminated)
