    messing with the file system

    i am curently working on a console app under windows. now it should search for a specific file type (i.e. *.txt or da*.txt) from any subdirectory which is specifyed (ie c:\tmp) and in it's subfolders (like dir /s /b). how can i do that. is there a tutorial on working with the fat filesystem?

    thanks

    Why do you need to work with FAT for that? What compiler are you using, each compiler has it's own set of function libraries for directory navigation. Check your compiler's documentation for that.

    my programm needs to collect all files *.txt in all subfolders from the curent list and scan them for a keyword. after completition it shall store all filenames and paths where the keyword is found in a .txt file.
    i'm using lcc and i'll check that documentation.

    thks

    p.s: why is browsing folders compilerspecific and working on files not?

    Not every OS has "directories", and even then, the interface to each type of directory can be different.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    even then it shouldn't be compilerspecific, more "libraryspecific". am i wrong?

    Isn't that the same thing? With your compiler, you (might) get a library that is for directory manipulation.

    The C standard is designed to be generic in this area, providing only basic file access.

    so, just because i'm wondering: could you build all the filefunctions like searching and so on from the ground up with just using c? i know you can when using asm.

    if yes, do you know where i could get a tutorial on that?

    Or you get the library with the OS. So it's not the same thing.
    For example the FindFirstFile function is OS specific, not compiler specific.
