Binary V/s Text files.

What is the difference between binary and text files?
Thank you for your reply.

What is the difference between binary and text files?
Thank you for your reply.They're both just files of (binary) data. The real difference is just in the way that they are read/written. Text files are 'line-delimited', having a sequence of cr/lf combinations (depending on platform) to separate 'lines' of 'text'.

  • Binary search in text files

    Hi all,
    I'm thinking about how to implement a binary sort to get,given a key, a value from a text file with a list of words in order. I saw randomaccessfile for j2se and I know that this work it's usually done by seek functions but how to do the seek work without the File class , with only the InputStream and Reader? I'm talking about the j2me midp 2 cldc 1.1 api, is there some methods or class to use for this thing? How could be implemented a binary search in a text file resident in the /res dir or the JAR or which could be the problems that cannot make possible this staff? If there was something like seek one way could be that one of decide a common length of words to read so going to the half of the text file it's possible with simply multiplication, and the do the binary search things.But for now I haven't found any resources or help.
    I hope you can help me to understand, thank you

    Hallo all,
    it is NOT the problem to locate the text I need to find in the fmb, or fmx.
    The problem is that since I want to change not only the text but also some more code around I want to do this in Form Builder - Object Navigator. And I'm not able to discover in which trigger or procedure the text appears.
    I do not want to edit fmx, or fmb in a text editor because I suupose theer are some checksums hidden for the format.
    -duro
    BTW in FMT there is no code seen (only some binary) for v6i as it was in v4.5.

  • Binary transfer of text files

    I'm trying to do this - edited FTPExtensionMap.txt
    accordingly, but get no joy. Files are still going up as ascii.
    I've restarted both DW and the OS (Win XP, DW 8). Has anyone
    experienced similar? I'm uploading to IIS.
    Thanks

    Guess I should have scrolled down to the app dev forum before
    posting - found my answer - there's two places that file resides
    and I edited the wrong one.
    Thanks...

  • Text files showing up as binary in Yosemite

    Anyone having trouble with text files?
    I have a dumpster of text files in which I keep a lot of general information, including lots of knowledgebase items I keep handy.  I have my text files set to open with TextWrangler.   I've used this as the main way I work since 10.6 -- I search with Alfred/Spotlight, and GREP search text files with TextWrangler.  This is the way I keep lots and lots of general notes that I need to reference.
    Well, with Yosemite, it previews all previous plain .txt files as binary, or at least that's what it looks like.  When I open and save them, they are now binary static/noise, and that's how they save.
    If I create a brand new text file and save as a .txt file with TextWrangler, then everything is fine.
    I don't think this is TextWrangler's fault, because previewing/opening files with other text editors, such as even TextEdit, still shows binary.
    As described above, this is pretty much a baseball bat right into my spokes.  It makes Yosemite unusable for me.

    The general approach at this time is to ask if you've checked for any problematic fonts (all languages) with Apple's Font Book (look in the Applications folder). Find and remove all duplicates also.
    Start there to be sure all fonts that are in play come out with a clean bill of health.
    Also, don't hesisate to perform wholesale deletion of old and/or little used fonts - be skeptical of anything that has come from Office 2008, including those related to an Equation Editor installation.
    By all means be sure your 3rd party apps are Snow Leopard compatible and know the rumors are that 10.6.2 will be play better w/fonts in some cases.

  • Loading from a Flat file: Binary and Text File

    Hi,
    Does anyone know what the difference is between loading from a binary file or text file?
    Ramon

    Hi,
    the difference is that text files contain lines (or records) of text and each of these has an end-of-line marker automatically appended to the end of it whenever you indicate that you have reached the end of a line.
    So what happens when we read from a text file is that the end-of-line character for the operating system that we are using gets converted into a low value end-of-string indicator and when we write to a file the appropriate end-of-line character(s) get written when we indicate the end of the line. This makes the reading and writing of text files much easier because the appropriate end-of-line markers are handled for us.
    With a binary file none of these conversions take place. When we read a binary file the end-of-line characters for our operating system will be read into the string and treated no different than any other character. When we write to a binary file the only end-of-line markers that are written will be those that we code into the output ourselves and hence will be exactly as we code it regardless of the operating system that we are running on. This makes it much easier for us when the file does not contain straight text and the end-of-line marker does not separate lines of text but rather appears as part of the non-text data content of the file.

  • How can I convert Binary File to Normal Text File?

    Hi,
    I need to read a binary file and need to conevrt as normal text file. The binary file contains some number & String (Names) with fixed length. It is the combination of Char, String, Integer, Byte & Single Bit.
    I used DataInputStream but I didnt get the expected output. Can anybody help me in reading a binary file?
    Thanks & Regards,
    Pattanaik.

    http://java.sun.com/docs/books/tutorial/essential/io/dataIO.html provides an example of using DataInputStream to do what you want.

  • Binary file text file

    I need to read binary file (actualy text file was saved in binary format) and convert to text file. After finished program, I must store this text file to binary format for use in next time. Anyone have any idea or suggestion will be usefull and great thanks

    thanksLook, every bit of text stored in a computer is stored in a binary format. The familiar ASCII bytes format is merely the most common of them. But, to the filing system, it's just another binary file.
    Java deals with many different ways of encoding text as binary. Mostly these are called "character encodings". The second most common one is UTF-8 which stores non-latin chacters as multi byte sequences. Also java can store and retrieve text from mixed file formats in which only part of the data is text.
    You'll get nowhere unless you can find out what binary format the text is stored in.
    In general java handles binary using Stream objects and text using Reader and Writer objects.

  • Binary search in a text file.

    Is it possible to carry out binary search directly in the text file without passing the file data into a List data, in order to save RAM?

    If the file is sorted, and if you know what byte position each record begins at, then, yes, using RandomAccessFile you can do this.
    I don't know if it's really the best approach though. If the file's not all that big, or if the relevant parts of its content can be represented in more compact form, then sorting in memory will be simpler and quicker.

  • Putting words from a text file into a binary tree.

    I am having problems figuring out how to do this.
    the text file will have a sentence like this
    Every one likes to play games.
    My Dog tore up my apartment last night.
    How old are you sir.I know how to put regular strings into a binary tree, but I don't know what to do in order to put these textfile strings into it.
    I thought of using string tokenizer but I couldn't get that to work because the sentences are not a specific length, they can be any length. Can somebody give me some tips on what to use?
    Thank you

But don't let that stop you. And don't wait around for people to validate your ideas. Try it and see what happens. You won't break anything. And when it doesn't work, figure out why and carry on.

  • Fm or method for converting  doc,pdf or text  files to binary format

    Hello,
    Are you aware of any function module or method which takes input as a file of type doc, pdf or text files and convert it to binary format? Kindly let me know.
    This is what i tried and was unsuccessful.
    i tried using gui_upload method and pass " asc" as file type while importing file of type .doc but it returns me string filled with strange characters.
    I did try converting this string to xstring using  cl_proxy_service=>cstring2xstring but i realized my 1st step of uploading file itself was wrong.
    Please let me know what can be done if you are aware of how to convert file of various types to binary.
    thanks
    Pooja

    hi All,
    thanks alot for the information and help provided by all of you.
    I did figure out a way where the word document or pdf  can be pretty much loaded with gui_upload. the file type used in the method would be "BIN" the following thing has to be done. declare data type as given below and file would be the complete path along with document name which has to be uploaded
    DATA: BEGIN OF res_line,
                raw(255) TYPE x,
             END   OF res_line.
      DATA: res_tab LIKE res_line OCCURS 0 WITH HEADER LINE.
    data :  wf_var_stringx TYPE xstring .
      CALL FUNCTION 'GUI_UPLOAD'
          EXPORTING
            filename                =  file
            filetype                = 'BIN'
            read_by_line            = 'X'
         has_field_separator     = ' '
         header_length           = 0
         header_line           = 'X'
          IMPORTING
            filelength              = l_filelength
          TABLES
            data_tab                = res_tab
          EXCEPTIONS
           OTHERS                  = 1.
    LOOP AT res_tab .
        CONCATENATE wf_var_stringx res_tab-raw INTO wf_var_stringx IN BYTE MODE.
      ENDLOOP.
    this will upload the file and will file the string x with its content.
    hope this helps to some of you.
    Thanks

  • Filling an object ArrayList from a text file

    Hi all,
    I am developing a project (for university) which has a class named "SupplierAgent", which is required to keep database of custom objects of type "InventoryItem". Basically these consist of a String (for the name of the item), an int representing the quantity on hand, and an int representing the unit price (in cents). I wish to have this inventory loaded from a text file rather than a binary file - that way the user can add new items to the file before loading the agent.
    I have included the code below, which works provided the file is rigidly structured. The main problem is the user having to type the path to the file: I cannot guarantee the user will have the file in any folder, and so the user is required to type in the absolute path. Is there any way to make this less annoying? Or is there a better way of loading a preset inventory while allowing the user to edit that inventory at will?
    I have included the current code below. it's not exactly in accordance with coding standards, because we are using the JADE agent architecture (hence why the method is called "action") rather than something more informative.
    I should also mention that it uses a command line interface. The "io" class basically includes a scanner and the System.out.println method. Its "yesOrNo()" method is for convenience: it asks the user a question and allows them to select y or n.
    public void action() {
                boolean loadFromFile = io.yesOrNo("Would you like to load the inventory from a file?");
                if(loadFromFile) {
                    BufferedReader br = null;
                    boolean fileFound = false;
                    while(!fileFound) {
                        io.output("Please enter the absolute path to the file, including filename extension:  ");
                        inventoryFile = io.input();
                        try {
                            FileReader fr = new FileReader(inventoryFile);
                            br = new BufferedReader(fr);
                            fileFound = true;
                        catch (FileNotFoundException e) {
                            io.output("File not found.  ");
                    String fileLine = null;
                    int lineNumber = 1;
                    InventoryItem item = null;
                    try {
                        while((fileLine = br.readLine()) != null) {
                            switch((lineNumber % 4)) {
                            case 1: item = new InventoryItem();
                                    item.setName(fileLine); break;
                            case 2: item.setQuantity(Integer.parseInt(fileLine));
                            case 3: item.setPrice(Integer.parseInt(fileLine));
                            case 0: inventory.add(item);
                        io.output("Inventory loaded successfully\n");
                    catch(Exception e) {
                        io.output("Error at line " + lineNumber + " of inventory file\n");
                        io.output("Unable to fill inventory.  Please ensure file is structured correctly\n");
                        io.output("See readme for explanation of file structure requirements\n");
                        myAgent.doDelete();

    You can use JFileChooser to allow the user to navigate to the required file.

  • Removing first line in text file... Memory and HD concern

    Hello all,
    I want to remove the first line of a text file. This is easy... One way
    to do it, is to find the first "end of line" caracter, strip the string
    and re-write the sting in file with the "strip to sreadsheet" VI.
    Since the file can be quite large (about 120000 lines), is this a good
    way to do it. Will it re-write all the line or just moving the "begin
    of file" pointer to the second line? If it re-write the whole file,
    this option is not very good since I could have to do this operation
    quite often. (I want the file to be a kind of circular buffer / backup).
    What do you think is the best way to do this?
    Thanks!

    I think you would have to read in all the data and write it to a new file, you could either keep the data in RAM or simply write to another file then delete the original, and then rename the temp one.  So obviously that is a lot of data and memory.
    My main question is are you trying to use a text file as a circular buffer?  If so can you tell us more about the data, ie is it strings of a constant length?  Does a user ever need to read the file or could we head binary?
    A solution would be to truly make the file a binary file, so you could actually seek through the file easier, and maybe make the first data chunk the location of the most recent write.  The obvious danger is then writing over existing data.  This solution is still risky because of the data writes.
    You may want to look at some of the other file formats like HWS which maintains a hierarchy of data for you so you can simply add and remove data from it.  However, a user will not be able to easily read it.

  • HOw to create a text file in the given path and delete it after the use?

    Hi all,
    I am trying to create a text file at the given path and delete the created file after the use.
    I am using following code.:
    import java.io.*;
    // write binary data as characters
    public class RanIO {
                                            public static void main(String f[])
                                                      // First illustrate append
                                                      String lineSep = "\n";
                                                      try {
                                                                     File temp= new File("C:/Ash","cute.txt");
                                                      boolean ch=temp.createNewFile();
                                                      if(ch)
                                                           System.out.println("file created");
                                                      else
                                                      System.out.println("file Not created");
                                                      //writing to file
                                                 /*     PrintWriter p = new PrintWriter(new BufferedWriter(new FileWriter("cute.txt",true)));
                                                      p.print("Emp NO");
                                                      p.close();*/
                                                                // Open fileWriter in append mode
                                                                               FileWriter fos = new FileWriter(temp, true);
                                                                               BufferedWriter bw = new BufferedWriter(fos);
                                                                               PrintWriter pw = new PrintWriter(fos);
                                                                               double d=550;
                                                                          // lineSep = System.getProperty("line.separator");
                                                                          pw.print("Hello");
                                                                          //pw.print( lineSep );
                                                                          pw.print( d );
                                                                          pw.close();
                                  boolean det=temp.delete();
                                                 if(det)
                                                      System.out.println("File deleted");
                                                 else
                                                      System.out.println("File not deleted");
                                                 } catch (IOException ioe)
                                                                System.out.println( "Append IO error:" + ioe );
    My problem:
    1)
    I am not able to write to the file. I want to know, where i am going wrong.
    It is giving error message like
    "Canot resolve Symbol: temp,"
    But, FileWriter Constructor should accept a File type parameter.
    here temp is a file parameter.
    If i am not using file=new file();
    i can't delete the file after the use. i.e if i use
    PrintWriter p = new PrintWriter(new BufferedWriter(new FileWriter("cute.txt",true)));
    how can i delete cute.txt after the use?
    2)
    I am not able to write to the text file. file is created but, a blank file.
    "Hello" is not written into the text file.
    can anyone help me in this regard
    Thanks in advance
    Ashvini

    Thank you Ram,
    But, i want to create a text file in Append mode.
    for that i used
    FileWriter fos = new FileWriter(temp,true); But, it is not accepting FileWriter constructor in
    this format. if i use
    FileWriter fos = new
    FileWriter("c:/ash/cute.txt",true); it works fine. !!!!!Here's the javadoc
    public FileWriter(File file,
    boolean append)
    throws IOExceptionConstructs a FileWriter object given a File object. If the second argument is true, then bytes will be written to the end of the file rather than the beginning.
    Parameters:
    file - a File object to write to
    append - if true, then bytes will be written to the end of the file rather than the beginning
    Throws:
    IOException - if the file exists but is a directory rather than a regular file, does not exist but cannot be created, or cannot be opened for any other reason
    Since:
    1.4
    Are you using jdk.13 or lower ?
    >
    ONe more doubt, Does flush method deletes a file?
    if not, then i need to use
    File temp=new File("c:/ash/cute.txt");
    FileWriter fos = new FileWriter(temp,true); //which
    is again a problem
    if(temp.delete())
    out.println("File is deleted");
    }I don't know whether i am taking it wrong ! or
    anything wrong with my coding ! but, after creating
    and writing data into a text file. I must delete it
    as it contains confidential informations.
    Regards,
    Thanks.'flush' writes to a file immediately. Else you should explicitly call 'flush' to write contents from buffer to underlying source.
    javadoc again
    PrintWriter
    public PrintWriter(Writer out,
    boolean autoFlush)Create a new PrintWriter.
    Parameters:
    out - A character-output stream
    autoFlush - A boolean; if true, the println, printf, or format methods will flush the output buffer
    cheers,
    ram.
    Question; What do you gain by opening a file, writing to it and deleting it in the same program ?

  • Write one line of numbers to a text-file or write multiple lines each iteration?

    Hi,
    I'm currently working on an application that has a few different while-loops running at the same time. One loop acquires the data (DAQloop), another shows the data (raw and processed data) on graphs (Graphsloop) and yet another stores the data in an open ascii text file (Storageloop).
    The data is passed on from the DAQloop to the Storageloop through a queue. At this moment I let the Storageloop take up the first element of the queue (the oldest) to store it in the textfile each iteration. I was wondering however whether it would be better to let the Storageloop take up all the elements currently available in the queue to store it in one go.
    Does anybody have any ideas on this? Which would be better performancewise? The textfile is already opened and is just passed on as a refnum.
    Thx!

    Using LabVIEW 8.5 on Windows7
    Solved!
    Go to Solution.

    With the normal LabVIEW file primitives, you will get your best disk speed when you write about 65,000 bytes to disk at once (or read, for that matter).  When I write similar code, I include a string buffer in the write loop.  Every time I get write data, I add it to the string.  When the string hits 65,000 bytes, I write to disk.  You could break this into three loops, as well - a read, buffer, and write.  Depending upon you current chunk size, you could see over an order of magnitude change in disk write speed.  This write operation is often throttled by the conversion from binary to ASCII, not the disk I/O.  If you do this, be careful with your buffer.  You can get some serious slowdowns depending upon how you implement it.  This post has some details and examples.
