    Clean Windows Temp folder and the User Temp folder?

    Hi everyone,

    Is there any function that can delete the files located in the windows Temp Directory and the user Temp Directory ( from Windows 98 up to Windows Vista ) ?

    If there is no such function, how can i get the path to the windows Temp Directory and the user Temp Directory under Windows 98?



    Best regards

    No, there is no such API.
    However, you can get the temp directory using GetTempPath API.
    Windows\Temp folder is not a temp folder at all. It was used before I think, but not anymore. But applications still puts junk there. There's no API to will return that path, so you can use the GetWindowsDirectory API and add \Temp to find that path.

    Thanks for quick reply.

    But i think that (GetTempPath and GetWindowsDirectory ) work only under Windows Vista, Windows XP, or Windows 2000 Professional ! Am i wrong?

    GetWindowsDirectory works on Windows 95+, but GetTempPath only works on Windows 2000+. The other way would be to check the tmp or temp environment variables.
    You can get an environment variable with GetEnvironmentVariable. Works on 95+.

    O.K i have tested (GetWindowsDirectory and GetTempPath) out on Windows 98 and both of them returned error code (120) which means:


    ERROR_CALL_NOT_IMPLEMENTED This function is not supported on this system.
    120
    0x78
    EDIT:

    Oops! i will test GetEnvironmentVariable and reply again. Sorry.

    What's the code?
    Are you using unicode?

    All of the previous functions works on Windows 98 just fine. And here is the code to test it :
    Code:
    #include <windows.h>
    #include <stdio.h>
    #include <string>
    #include <iostream>
    
    #define BUFSIZE 4096
    #define VARNAME TEXT("tmp")
    
    int main()
    {
        DWORD dwRetVal;
    	DWORD dwRet, dwErr;
        DWORD dwBufSize=BUFSIZE;
    
    	CHAR envtemp[BUFSIZE];
        CHAR tempBuffer[BUFSIZE];
    	CHAR getwindowsBuffer[BUFSIZE];
    
         // Get the temp path.
        dwRetVal = GetTempPath(dwBufSize, tempBuffer); 
    	
    	
        if (dwRetVal > dwBufSize || (dwRetVal == 0))
        {
            printf ("GetTempPath failed (%d)\n", GetLastError());
        }
    
    	std::string tpath;
    	tpath = tempBuffer;
    	std::cout << tpath << " : Is the Temp Directory path\n";
    	
    	// Get Windows Directory.
    	dwRetVal = 0;
    	dwRetVal = GetWindowsDirectory(getwindowsBuffer, dwBufSize); 
    
    	    if (dwRetVal > dwBufSize || (dwRetVal == 0))
        {
            printf ("GetWindowsDirectory failed (%d)\n", GetLastError());
            
        }
    
    	std::string wpath;
    	wpath = getwindowsBuffer;
    	std::cout << wpath << " : Is the Windows Directory path\n";
    
    	dwRet = GetEnvironmentVariable(VARNAME, envtemp, BUFSIZE);
    
    	if(0 == dwRet)
        {
            dwErr = GetLastError();
            if( ERROR_ENVVAR_NOT_FOUND == dwErr )
            {
                printf("Environment variable does not exist.\n");
            }
    		else
    		{
    			printf("GetEnvironmentVariable failed ( function call not supported )(%d)\n", dwErr);
    			return FALSE;
    		}
        }
    	else if(BUFSIZE < dwRet)
        {
           
                printf("GetEnvironmentVariable failed (%d)\n", GetLastError());
                return FALSE;
        }
    
    	std::string envpath;
    	envpath = envtemp;
    	printf("%s : Is the path for variable %s\n", envtemp, VARNAME);	
    	return (0);   
    }
    Just last question:

    Under Windows2000 and above the program above returns the User Temp Directory, but under Windows 98 it returns the Windows Temp Directory!
    Could it be that Windows 98 does not have a User Temp Directory or i must use another API function to get it ?

    95/98 uses Windows\Temp AFAIK.
    And another tip for you:
    http://cpwiki.sf.net/Indentation
    Indentation is import.
    But perhaps you might need to read
    http://cpwiki.sf.net/User:Elysia/Indentation
    too.

    Tell me if you find one better than the other and if anything is missing.
