    I am not get something, so forgive me. I have moved those enum values as #defines, but of course, now I get error from struct: doesn't know who is FILE_FLAGS flags; from level1 struct.

    /*
    typedef enum {
    FILE_READONLY = 0x00000001,
    FILE_HIDDEN = 0x00000002,
    FILE_SYSTEM = 0x00000004,

    FILE\_DIRECTORY = 0x00000010,
    FILE\_ARCHIVE = 0x00000020,
    FILE\_DEVICE = 0x00000040,
    FILE\_NORMAL = 0x00000080,
    
    FILE\_TEMPORARY = 0x00000100,
    

    ....
    .....

    }FILE_FLAGS;
    */

    #define FILE_READONLY = 0x00000001
    #define FILE_HIDDEN = 0x00000002
    #define FILE_SYSTEM = 0x00000004

    of course, FILE_FLAGS enum has disappeared ... obviously, I don't understood something ... but what ?

    struct level1
    {
    FILE_FLAGS flags; // <-- error
    ....
    };

      Ok, but even flag is comming as function parameter, just like this:

      static void SomeFunction(level1* na, FILE_FLAGS flag)
      {
      ....
      na->flags |= ~flag;
      ....
      }

      So, I guess I cannot give up FILE_FLAGS enum ... don't I ?

        Change this parameter to be

        static void SomeFunction(level1* na, int flag)
        {

          Add this line somewhere before the first reference to FILE_FLAGS :

          typedef int FILE_FLAGS;

            I encounter another error if I made these modifications:

            data->com = na->flags & ATTR_IS_COMPRESSED; // <-- error C2059: syntax error : '='

            (where data->com is int) because now ATTR_IS_COMPRESSED is #define, not part of enum FILE_FLAGS ...

              What is data->com?

              That is not the reason. I can only assume that you have done a partial change and some parts of your code are still incorrect. If you still have the FILE_FLAGS enum then it is going to cause problems. It would probably help if you showed all the code portions that are connected. It is difficult to be certain of the answers when looking at only a single line of code.

                      The fact is like that: I have an error:

                      the error is reported here:

                      where: data is a struct:

                      and na is

                      ATTR_IS_COMPRESSED

                      is from here (from my modifications):

                        Not sure why you posted all that back to front ... However there are a couple of simple mistakes: #define statements do not require an = sign. They should be

                        #define ATTR_IS_COMPRESSED 0x0001
                        #define ATTR_COMPRESSION_MASK 0x00ff

                        The name data refers to a struct definition, not a variable. You need something like:

                        typedef struct
                        {
                        .....
                        int com;
                        ...
                        } DATA;

                        DATA* data;

                        I am assuming that you actually assign the memory required for both structures at some point further on.

                          That was the problem, on #define: I assigned with '='. My bad !
