    Do you mean this?
    Code:
    dir /s/b progname.exe

    Assuming that you do not know the location of X program, then you would use FindFirstfile and FindNextfile and recursivley call the file finding function to search for X program.

    Code:
    char szFileName[MAX_PATH];
    HINSTANCE hInstance = GetModuleHandle(NULL);
    
    GetModuleFileName(hInstance, szFileName, MAX_PATH);
    szFileName being the char array to copy the file name to, you can replace MAX_PATH with whatever no. you want, or you could probably use a string (such as str1.c_str()) in place of a char. But that will return the path to the executable file (C:\test.exe), so you'll have to change that to C:\ or whatever.

    Code:
    #include <direct.h>
    
    ...
    
    void Foo()
    {
    	...
    
    	char *tempPath = new char[512];		  // Create a cstring to store the path in
    
    	getcwd(tempPath, 511);				// tempPath now stores the path of the directory
    									// of the *.exe file.
    	...
    
    	cout << "This program has been executed from the directory: " << tempPath;
    
    	...
    
    	delete [] tempPath;
    }
    I'm not good at writing snippets of code like that, but I think you get the idea, getcwd() takes two parameters, the first is a cstring that will hold the directory in it and the second is how much space you are giving it.

    Well, you can either execute "dir /s/b somename.exe" from inside a C program, using a pipe to read the output, or redirect the output to a file, then read the file. Just remember that not everyone has one big disk, there may be several physical or logicial disks, so you need to get a list of those [there was a post on how to do that in Windows just a few days ago].

    Or, if you really want to do it in your application, use the method described by mikeman118. There will be little difference in performance, since the speed of finding a file is mainly dependant on the time it takes to get the relevant data off the disk, rather than how you get to the final data.

    But really, it's probably much easier to just write a little batch-file to do the same thing, rather than C.
