Check if file exists returns false. File is in system32

I'm having a problem detecting if a file exists which was simply copied to the system32 directory. I tried moving the file to various other directories and simply using a vi with the "Check if file or folder exists" action. I've narrowed it down to not being able to find the file if I copy it to either c:\windows or c:\windows\system32.
I thought this could be a permissions issue, but did my best to assign the user name full control of the folders.
Another interesting thing is if I make the file input a control and click on the "folder" icon to open a list of files, I cannot see the newly copied files in system32 directory either. Very strange.
This is on a Dell PC, Windows 7 professional/Labview 2010 SP1 (note I am running the vi. as an executable on this machine). Could it be some setting in my project build?
Solved!

If you're using Windows 7 64-bit, it may be related to the problems the user was having here:

It may be that the LabVIEW functions are 32-bit and are getting redirected.

File.exists returns false

File.exists returns false if the File object represents a symlink that is pointing to a non existing file.
How can I make it return true? I am using File.exists in a condition to
check if a symlink exists before calling File.delete.
I am using JDK 1.1.8.
Any help is appreciated.
Anil

Interesting. But it doesn't hurt to call delete() even the File doesn't exist, does it? Could you clarify why you need to confirm that before calling delete()?

File.exists() returns false even when the file exists

hi,
the exists() function of java.io.File function returns false even when the file exists on the file system. why is this? i checked the path of the file which gives me the correct path, but exists returns false. can anyone help?

post some of the code you�re using - then maybe I can help you out

File.exists() returns false for existing file, help :)

Hi all,
I'm having the STRANGEST behavior... I'm working on a simple DNS management system, and before I overwrite a zone file, I want to check if it exists... but exists() is returning false even when the file exists.
Here is my code snippet:
finest( "Checking the existance of "+filename ) ;
File zoneFile = new File( filename ) ;
if ( zoneFile.exists() ) {
    finest( "Zone File "+zoneFile+" already exists." ) ;
    throw( new ZoneFileExistsException( fqdn ) ) ;
else {
    finest( "Creating Zone File "+zoneFile ) ;
    ...It's producing this in the log (I cut off the timestamp parts):
Checking the existance of /opt/DNS/db.testingbutler222.com
Creating Zone File /opt/DNS/db.testingbutler222.com
but...
# ls -l /opt/DNS/db.testingbutler222.com
-rw-r--r-- 1 root other 733 Aug 27 19:23 /opt/DNS/db.testingbutler222.com
So... as you can see, the file CLEARLY exists... what the heck am I doing wrong or misunderstanding? This can't really be a bug in File, can it?
Kenny Smith

Hi,
Thanks for your response, but as I showed in my first post, I'm using absolute paths. My log file contains this:
Checking the existance of /opt/DNS/db.testbutler222.com...
Existance of /opt/DNS/db.testbutler222.com=false
# ls -l /opt/DNS/db.testbutler222.com
-rw-r--r-- 1 root other 695 Aug 29 12:17 /opt/DNS/db.testbutler222.com
I don't understand what is happening... I wrote a separate class that just tests the existance of a file, and that one is reporting the existance correctly.... (the source code is found in the second post above) I don't understand why my servlet code can see the file.
I have jakarta-tomcat running as root, and the file I'm checking was created by the same servlet. I've double checked permissions and such, just to make sure it wasn't that.. but it's still not working.
I even added code to create a FileReader from the file, that way if it throws a FileNotFoundException, I would know the file doesn't exist... and even though the file does exist, it throws the exception. :(

File.exists() returning false eventhough in reality the file exists

Hi,
I am trying to create a PDF file using FDFMerge software.
For creating the PDF file, I need to execute a shell script from command-line, which I am doing using "Runtime.exec".
( I opted for this 'RunTime.exec' approach so as to read the output generated by the shell script.)
After executing the shell script and reading all the output generated by the process, I am trying to check if the PDF file exists in the location the process created.
When I do File.exists() its returning me "false" eventhough in reality the file exists.
Any guess, why this is happening?
Thanks in advance.

File Doesnt Exist / Returns false

Hi Folks,
I was just mucking around with some file IO and I used the following code to try verify a files existence before trying to open it:
File Temp1 = new File(fullyQualifiedFileName);
     System.out.println(Temp1.getAbsolutePath());
     doesExist = Temp1.exists();
          System.out.println(fullyQualifiedFileName);
          System.out.println("Does "+ fullyQualifiedFileName +" Exist? -"+doesExist);
The path prints correctly, the file does exist at the location give, the filename is correct but for some reason it returns false. Any ideas?

Does the user have access rights to the file?

File exists always false

I'm making a mobile app for iOS and I have files in both the applicationDirectory (inside the app) and the cacheDirectory.
No matter what I do a check on file.exists always returns false even though it is there - it's a video and it can play so it's there alright.
What is going on?
I have a string representing the path eg. "/assets/video.mp4"
var f:File = File.applicationDirectory.resolvePath(filePath);
trace(f.exists) //false

When I trace the nativePath of the file I am trying to find it shows "C:\Users\User\AppData\Roaming\Arakaron.debug\Local Store". This is the exact path I am following in Explorer. Now, instead of applicationStorageDirectory I can do documentsDirectory and it reads that the file is in fact there. With the applicationStorageDirectory it only registers that the file exists after I copy from the embedded db file.

File.exists() returs false even the file is present in the specified path

Hi,
When i try to run the following program which checks whether the file exists in the given path or not
public class FileCheck {
public static void main(String[] a){
String str = a[0];
File f = new File(str);
if(f.exists())
System.out.println("File Exists ");
else
System.out.println("File does not Exists ");
So on solaris 10(korean) we have file named in korean language under "usr" directory. When i try to run the above program on solaris 10(Korean) using the default jre (1.5)with the parameter "/usr/file name in korean language" .The output of the program is "File Exists"
And when i run the same class file using the jre (1.6) which is installed in our application which is an english version with the same parameter ""/usr/file name in korean language"
The output of the program is "File does not exists".
And this problem is only with the files which contain the name in korean language.
So do we need to set any properties for the jre in our application to work for files which are named in korean language. Any help will be highly appreciated.
Thanks,
GPK

My guess is that Java 5 and 6 are picking up the file system encoding differently. As a consequence, the JVM is either:
1. reading and converting your command line argument incorrectly, or
2. reading and converting the file name from the file system incorrectly.
Write a quicky, short app that prints out the file encoding of your host. Run this under 5 and then 6. Do you see different outputs?

Reasons File.Delete returning false

Hi,
I always assumed that if file.delete did not delete a file, it would raise an exception - however, today I have found out otherwise.
What are some of the reasons why File.delete would return false (without throwing an exception). I've haven't seen the results of a chmod (which I am waiting on, but I have been assured they are set correctly - besides, I can delete files on the server directory through an Explorer on my Client PC.
Thanks,
Red.

Thanks,
It actually turned about to be an Oracle based setting (in ora.init) which was causing the problem.
Of your answers -
1. I believe would return a permission exception.
2. It would think would raise an acess exception
3. Should return false
4. Would likely raise an exception
Although I could be wrong...
Thanks again,
Red

Java script in HTMLDB to check if file exists in Unix file system

How do I use javascript to check if file is exists in Unix file system. I would like to dispaly the columns only if file is exists.

Hello,
This is one of those features that the manuals do not cover.
How to use and build AJAX features could be a whole book all by itself, and it's not really HTML DB specific feature even though we have built some hooks in application and javascript to make it easier.
Take a look at this thread
Netflix: Nice UI ideas
and I've built some examples here
http://htmldb.oracle.com/pls/otn/f?p=11933:11
Or just search the forums for AJAX or XMLHTTP

File.exists() vs. File.getAbsoluteFile().exists()

Is there a well known cause for File.exists() to have a different return value from File.getAbsoluteFile().exists()?
This thread: http://forum.java.sun.com/thread.jspa?threadID=428403&messageID=2595075 says that this can be the result if you attempt to change your current working directory, but as far as I can tell I don't do anything like that, no System.setProperties or anything. I am running from JUnit, but it doesn't seem like that would make a difference. Any ideas of what I should look for?
Thanks!

Thanks for your reply. I have looked through the API, and I understand the difference between relative and absolute path if that's the difference you mean. My (incorrect, apparently) assumption was that relativeFile.exists() would always refer to the same location as relativeFile.getAbsoluteFile().exists()-- That is, at one point or another, you more or less concatenate the working directory and the relative path before checking to see if that exists
I'm sorry I cannot post any example code because I don't know what could cause this situation. I was hoping for a general possible cause or two that might give me an idea where to look in my application

Java.io.File only returns similar file names

I have written a bean which reads a directory and places the file names in an array, which can be accessed by a JSP page. At first, the files inside the directory were named wb_1.jsp, wb_2.jsp, wb_3.jsp and so on. When I change a filename to something like work.jsp, it still appears in the file list, but when I rename it to something like identify.jsp, it doesn't!
If I count the array, it does read the correct number of files.
Class FileHandler
// Imports
import java.io.File;
// Class
public class FileHandler
     // Constants and variables
     public File dir;
     public File[] files;
      * Returns the number of files found inside the given directory
     public int showFiles()
          try
               setDir(getDir());     // Get file directory as set in the bean property
               files = dir.listFiles();     // List the files found inside the directory
          catch (Exception e)
               System.out.println(e + " : No files found to return a value");
          return files.length;      // Return the number of files
      * Returns the file name by using the in value in the files array
     public String returnFileName(int in)
          return files[in].getName();     // Return the name of the file
      * Sets dir file type to the setproperty value in
     public void setDir(File in)
          dir = in;     // Set class variable value for dir
      * Returns the dir value
     public File getDir()
          return dir;     // Return the setproperty value for dir
}And the JSP code which reads the array
out.println("<select onChange=\"jumpMenu('top',this,0)\" size=\"5\" style=\"width: 200\"");
String fileName = new String();
for(int x=0; x<file.showFiles(); x++)
     fileName = file.returnFileName(x);
     out.println("<option selected value=\"beheer.jsp?action=2&file=" + fileName + "\">" + fileName +"</option>");
out.println("</select>");

I forgot bean properties im the above code lines. Here it is, just in case.
<jsp:useBean id="file" class="FileHandler" scope="page" />
<jsp:setProperty name="file" property="dir" value="C:\\IBM Websphere workspace\\Project\\Web Content\\WEB-INF\\include" />

Check if a file exists in network dir (JS)

I've found an old post that has pointed me at:
if (myFile.exists){
alert("File Exists");
else
alert("File doesn't exist");
The problem is that when I use the path macname/volumes/dir/folder/folder/file.indd (which was created from variables) as myFile the script doesn't find a file that I know exists. All I get is the "File doesn't exist" alert.
Do I need to define myFile as being a string?
I'm still fumbling my way around JS, and converting Applescripts to JS to work cross-platform. Thanks in advance....

To get the path to a file i normally use this little script:
// JavaScript Document
var myFile = File.openDialog("Choose a File");
if((myFile != "")&&(myFile != null)){
    alert("Path: " + myFile + "\nType: " + myFile.type);
Perhaps this c/p can help you:
function mounter() {
    var myDocument = app.activeDocument;
    // we are saving the preview
    var destination = "/Volumes/myfoldername";
    //var destination = "/Users/tn/Documents/Tryksager/Design/";
    var volume = "afp://sub.dn.com/myfoldername";
    try {
        with (myDocument) {
            if(file_name = get_filename(name)) {
                    if (Folder(destination).exists) {
                    //alert("Folder exists: " + Folder(destination));
                    } else {
                    if (confirm ("Mount volume?", false, "Mount volume")) {
                        mount_volume();
                        // volume mounted, do what you need
                    } else {
                        alert("Could not mount");
    } catch ( err ) {
        // No error warning
    function mount_volume() {
        var myScriptFolderPath = pluginPath + "/resources/"; // Path to the applescript

File problem - checking the existence of a remote file

I have absolute paths to several text files from a ftp server (which don't require any
authentication and can be accessed over the internet).
I am trying to write a Java method that can check any of the above absolute ftp file
paths and returns true/false depending on whether the file exists/doesn't exist.
I tried somewhat this way:
File current_file = new File(absolute_file_path);
// absolute_file_path comes as a parameter
// e.g. "ftp://ftp.test.com/myfile.txt"
if(current_file.exists()) return true;
// if the file exists return true
return false;
// otherwise return false
Then I ran the program in my local machine which has internet access. But it returned
false for all the files (even if the file exists). Seems like it's unable to get those
files.
Could someone please tell me how can I rewrite my program so that it can be executed
locally.
Thanks,
SQ

Does anyone know if URL and URLConnection support FTP
directly? I can imagine downloads being simple, but
how about uploads? Never tried with FTP myself.Yes, they do. But uploads don't work properly with Java 1.3. (Note: I only know this because I've seen questions asked about it here, not from personal experience.) If I wanted to know whether a certain file existed on an FTP server, I would use an FTP client that could tell me that. Such as the Jakarta Commons/Net FTP client.

Java.io.File exists() problem

I have a web application deployed on a Windows 2000 server and am running Tomcat 4. I want to check for the existence of an image file before displaying it and am trying to use the java.io.File.exists() method. I am using the following code:
String strPicUrl = "/images/thefile.jpg"; //Actual value comes from database
File theFile = new File(application.getRealPath(strPicUrl));
out.print("File Exists: " + theFile.exists() + "<br>");the actual file name in this example is "/images/theFile.jpg", and theFile.exists() always returns true if the file is there, but differs in case. If I try to display the image it doesnt show up under Tomcat because aliasing is turned off by default. I need to find a way to determine if a file exists based on actual case matching. This way if I get a "true" value, the file should be accessible and/or viewable via the JSP engine.
Any ideas how to perform a case sensitive "exists()" regardless of the underlying OS file system?

This looks awesome, but when I tried to implement it without creating a class, I get a method error. Here is the code below:
String theDir = "C:\\Dir\\Subdir\\";
FileFilter theFilter = new FileFilter() {
     private String _theFile = null;
     public boolean accept(File file)
          if (file.isDirectory()) return false;
          String fileName = file.getName();
          if (fileName.endsWith(_theFile)) return true;
          return false;
     public void setTheFile(String theFileParam)
          _theFile = theFileParam;
theFilter.setTheFile("theFile.jpg");When I run this I get the following error:
[javac] ...blah error stuff...
[javac] cannot resolve symbol
[javac] symbol : method setTheFile (java.lang.String)
[javac] location: interface java.io.FileFilter
[javac] theFilter.setTheFile("theFile.jpg");
Since I am invoking the FileFilter object directly and not instantiating it in a class, is that causing the error or am I declaring "setTheFile()" wrong?

Check if file exists returns false. File is in system32
