    hi everyone
    occasionally when I try to open a file, I.M. told there is no specified application to open this file. for example exec and genDus22.b02
    I tried using that application Finder with no lock.
    and hoping someone can help me with this.

    I don't understand the question. What kind of file are you trying to open?

    I don't understand this question either.. sounds like you are trying to open a file type that iss not supported by any application you have.

    If that happens, you will have to download an application that opens those files. Use Google to search .[file extension] file mac :)

    It sounds like a data file for a spanned archive. For example, when you download a 500MB program, instead of having one large 500MB file, you might have five 100MB files, and these files usually have the extension of a01, a02, etc. And then you have a master file which compiles all these files into the program. There is no way to individually open each file, so all you have there is a waste of space.

    I'm back
    thank you for your help everyone
    I have said files when I meant documents.
    these documents are Unix Executable,
    are these documents best left alone.
    this is my 1st Mac.

    Can you give some examples? If something really is a Unix Executable, that would be a program you run from the command line, and generally you wouldn't even see them without looking for them (unless you're someone who uses the command line a lot, etc.)

    But I'm guessing you're talking about some other kind of file you have. What program was it created in? What type of file is it?

    If you know what type of file it is and know you have something to open it with, you can right click on it, and pick an application to open it. You can also "get info" and choose the application that's set to open files like that.

    I found to programs that will open those files.
    the 1st 1 the 2nd 1
    the question is with there is a program will it be safe to open it or not. I do not know where it came from. should I deleted or not.

    I'm not sure what you mean.

    Do you know where both of these files you're trying to open came from? Do you know what type of file they are? Do you know what program they were created in?

    If you don't know where these files came from, there is a risk in trying to open them (or downloading them to your system in the first place). Less of a risk since you're using a Macintosh, but still, there's a risk.

    I wish to thank everyone for their help.
    I have deleted those documents when I manage to get them to open.
    I have received the warning stating there was an application within it.
    so I have opened a couple of them and nothing happened.
    so I decided to just delete them.
    thanks again for all the help,,
