    Hello George_George, I'll tell u the exact problem u r having and how to rectify it. Your Code:------------------------------------------------- int remove_non_empty_directory (const char* path) { WIN32_FIND_DATA FindFileData; HANDLE hFind; int rtn; hFind = FindFirstFile(path, &FindFileData); if (hFind == INVALID_HANDLE_VALUE) { FindClose(hFind); return -1; } else { // delete 1st file rtn = DeleteFile(&(FindFileData.cFileName)); `` if (0 == rtn) { ErrorExit (NULL); } // List all the other files in the directory and delete all files while (FindNextFile(hFind, &FindFileData) != 0) { rtn = DeleteFile(&(FindFileData.cFileName)); `} FindClose(hFind); }` `` ---------------------------------------------------------- The problem lies in the highlighted lines. FindFileData.cFileName contains only the FILE NAME, NOT PATH. So the problem. Rectify it by replacing the highlighted lines by DeleteFile(path);

      That won't work as he is most likely passing in just a folder name, or a folder name with a wildcard attached. He should take the original path (excluding wildcard) and then add the filename from FindFileData.cFileName and then Delete that. regards,

          Hi I was just looking at your problem and why not try someting completely different. You could create a batch file which deletes the files within a folder. 1. Create a new text file for writing to (say on your c:\) with the extension of ".BAT" 2. Write to that file the path of the directory you want to delete, fprintf(cfile,"del %s\*.*",pathname) 3. Close the file 4. Using the SPOOL command run the file. Just a quick solution to your problem. Bry.:-D

              Hello everyone, I am using the following program to delete all files in a specified directory. But when running, no files could be deleted, and the related error information is, failed with error 5 -- access denied. Anything wrong with the program? remove_non_empty_directory ("c:\\temp\\non_empty_dir\\*"); // ErrorExit implementation from MSDN // http://msdn2.microsoft.com/en-us/library/ms680582.aspx int remove_non_empty_directory (const char* path) { WIN32_FIND_DATA FindFileData; HANDLE hFind; int rtn; hFind = FindFirstFile(path, &FindFileData); if (hFind == INVALID_HANDLE_VALUE) { FindClose(hFind); return -1; } else { // delete 1st file rtn = DeleteFile(&(FindFileData.cFileName)); if (0 == rtn) { ErrorExit (NULL); } // List all the other files in the directory and delete all files while (FindNextFile(hFind, &FindFileData) != 0) { rtn = DeleteFile(&(FindFileData.cFileName)); } FindClose(hFind); } return 0; } thanks in advance, George

              Why not just use SHFileOperation()?

                I was not concerned with privileges. I was simply suggesting replacing dozens of lines of code with a single one.

                  Because I suspect on Windows Mobile it is not supported -- I need to write program for both Windows desktop and Window CE. regards, George

                        Thanks DavidCrow, This function is convenient to use, but I am not sure whether we can use it on Windows CE. regards, George
