    Deleting a set of file

    Hi, I want to delete a set of files but in an efficient way.
    I have an array of string called filesToUse that contains the list of files names to keep in disk. Then, I search in my folder all files but I need check every files do not match with any element in my array. By example:
    foreach(string sFile in System.IO.Directory.GetFiles("C:\\*.bmp"))
        bool flag = false;
        foreach (string s in filesToUse)
            if (s.Equals(sFile))
              flag = true;
        if(flag) System.IO.File.Delete(sFile); //anyone of these are in filesToUse
    I think that both foreach is unnecessary, any better solution without use 2 for's?
    Thanks in advance

    hi there,

    this is not a dotnet solution, but deleting files is recommended with forfiles.exe utility.

    here is information about forfiles.exe -->

    best regards,
