Check if a file or folder exists question

• Check if the file exists returns the value false. File is located in system32

  I'm having a problem to detect if there is a file that has been simply copied to the system32 directory.  I tried to move the file to various other directories and simply using a vi with action "check if a file or folder exists.  I narrowed down it to not be able to find the file if I copy into c:\windows or c:\windows\system32.

  I thought it could be a permissions problem, but not my best to assign the user full name control folders.

  Another interesting thing is that if I do file an input control and click on the "folder" icon to open a list of files, I see either the files newly copied to the system32 directory.  Very strange.

  It is on a PC, Dell, Windows 7 Professional/Labview 2010 SP1 (note that I use the vi. as an executable on this machine).  Would it be a setting in the generation of my project?

  If you are using Windows 7 64 bit, it may be related to problems that the user has been seen here:

• UTL_FILE. OPEN_FILE question to check if a file exists and is not empty

  Hello
  
  I'm writing a code in 3 separate files are created based on certain conditions of parameter for the call of the extract.
  Say that the parameters are NULL, 'A' and 'B '.
  When the Null State is passed to the call of the extract then it should create file A and B if the records are found. If this isn't the case, then create empty files.
  It is possible that the setting of the extract is just 'A', then it would create a file say no zero and B with file from scratch.
  Now when the extract is called with the parameter 'B' and if the file already exists and is not empty then I shouldn't touch/crash with empty folders.
  Is there a simple way I can do this to check if a file exists and is not empty?
  
  I use
  OPEN_FILE
  (gv_utl_file_path
  lv_file_name
  lv_file_handle
  );
  
  Help, please.
  Thank you

• "cannot complete the operation because the file or folder already exists.

  Hi all

  Just spent in ghettovcbg2 and I must say it is indeed very nice.

  Just a small question though.

  It's not like it is possible to do multiple backups per day?

  I get the error "cannot complete the operation because the file or folder already exists.

  (1) is it only possible to make 1 backup per VM a day?

  (2) can I save to NFS I don't store files in the ESX Server data store?

  It should work automatically, this is more than a warning. You should be able to run more than one backup per day? If that is not the case, please read the FAQ here - http://communities.vmware.com/groups/ghettovcbg2 and then to provide me with the details requested.

• How to check if a file exists?

  Hi guys.

  I am running javascript in Acrobat .pdf file created in LiveCycle Designer.

  I need to check in silence if an external file outside the open document (C:\something\something\something.pdf) exists or not.

  I understand that I'm only able to do this as a function of confidence within a script to the folder level javascript.  I am familiar with those.   The problem is, I don't know what function I should use and will have a difficult time in the research on it.

  Try to use: doc.exists?

  Try to open the document with a function and catch the error if the file does not exist?

  I'm not so sure that if I just spend my path as a string, say "/ C/Something/something/something.pdf" or if I should first deal with the file as an object like:

  var myFile = new File("/C/Something/something/something.pdf") (which was not in Acrobat... don't try to run it as a function of confidence)

  Please notify.

  Thank you!

  I finished this figure myself.

  XFA/JavaScript in my paper, I call a custom function that I have written and pass a string (or a string variable containing) my file path for that I would like to check:

  if(typeof(MJS_FileExists) == "function") {
      try {
          if(MJS_FileExists("/C/something/somethingelse/filetocheckfor.pdf") == true) {
              xfa.host.messageBox("file is there");
          } else {
              xfa.host.messageBox("file is NOT there");
          }
      }
      catch(e) {
          app.alert("Processing error: "+e)
      }
  }
  

  The function I call is a folder level javascript.   You have to maybe do some Googleing on how and where to install them.   In the my file .js file real javascript level where the function is housed I use:

  var MJS_FileExists = app.trustedFunction(function(filename) {
      app.beginPriv();
      var existingDoc = false;
      try {
           var checkDoc = app.openDoc(filename);
           checkDoc.closeDoc();
       existingDoc = true;
      } catch(e) {
       existingDoc = false;
      }
      return existingDoc;
      app.endPriv();
  });
  

  It took me a lot of trial and error.  It sucks there is not a lot of in on the internet on how to do it via Acrobat / Live Cycle.   Hope this helps someone else.

• How to check if a folder exists

  Hello
  
  I have a custom filter component:

  public class BarcodeMetadataFilter implements FilterImplementor{
  }

  I check here if the file exists in xCollectionId value, so I have two qustions:
  
  (1) should what service I call to check if the file exists?
  (2) how to call this service from the filter?
  
  Kuba

  Call a service such as COLLECTION_GET_INFO. Pass the parameter dCollectionID which must be xCollectionID. If you receive and error, it may mean that the folder does not exist. You should check the error (exception) to ensure what he wants to say to you is that the folder does not exist.

  http://docs.Oracle.com/CD/E23943_01/doc.1111/e11011/c07_folders.htm#i1082467

  The following blog post will show you how to run a service, a filter: http://jonathanhult.com/blog/2012/06/execute-a-service-from-a-java-filter/

• How can I check if a file exists in the CVI real-time?

  Also, it would be nice if designated so help file functions have been supported in real time or now.

  I tried this:

  If (GetFileAttrs (DataFileName, NULL, NULL, NULL, NULL) == - 1).

  You can check if a file exists in the CVI real-time using GetFileInfo.

• WARNING 1909. Could not create shortcut < filename > .lnk. Check that the destination folder exists and that you can access.

  When I try to install some programs, I get the following message:

  WARNING 1909. Could not create shortcut .lnk. Check that the destination folder exists and that you can access.

  How this issue is resolved?

  I had this same problem trying to update iTunes. I found a solution here:

  by OneRing2Rule

  "When the installation fails and you get the error 1909, stop." DO NOT CLOSE the installation or click a button. Simply open another window, navigate to the data directory of program (C:\Program Data\whatever-the-name-of-the-directory-is C:\Program Apple for installation of iTunes), do a right click and select Properties, clear the read-only attributes at the bottom of the box and apply. Then go back to the installation failed and click Retry. »

• "Cannot run the script at line 1. File or folder does not exist. »

  Whenever I have start AfterEffects, I get an error as he is looking to find my recent projects.  The error is as follows: "unable to run the script at line 1. File or folder does not exist. "I haven't changed the location in one of my project files.  It's the same external drives that I use for months.  When I click on OK the same window opens several times and then finally the historic window opens completely blank and empty.  I am able to reopen projects however since the RECENT PROJECTS drop in the top bar.  It is a very strange and disturbing behavior.  In addition, I always use 13.7.2 because when I go to update it is impossible to connect and gives me this error.  I sat with Adobe support for an hour today, and we couldn't understand.  As I am in the middle of major projects, I decided to not update, but this error at startup is very worrying.  Someone has an idea of what could go wrong or how I can fix this?

  Thank you very much for your time.

  -Fredo

  

  Ok!  Just got a response and an Adobe technical support solution.  The problem is that there is a problem with these versions of sequels (and I found the same problem in first to my horror this morning as well!) and the last couple Mac OSs.  The solution is to close the window "library".  It is then normally.  Apparently they fixed in the last update, but I found the same problem on my second computer, which has been updated.  Anyway, if anyone has this problem, close your cc library window.  Voila.

• How to run a job that will check if the files exist?

  I have a file in real time ' ' which has about 15 files (test1.txt, other.txt etc.) txt, theres is other jobs that nothing related to coldfusion that if something fails then the file no longer exists.

  So I want to create a job if there is no such thing as a txt file so he sent me an email.

  What would be the best way to do something like that?

  I have to check for every individual txt, something like file?

  <cfset Pathtest = "\\folder1\dept\Alerts\other.txt">
  
  <cfif !fileExists(Pathtest)>
    <cfmail ...>
    sent me a email
    </cfmail>
      
  </cfif>
  

  If all the files are in the same directory, you can create a list separated by commas (or even a table) file names, and that loop.

  
  
  
      
          ... email me ...
      
  
  

  HTH,

• Check if a file exists in the network dir (JS)

  I found an old post that made me to:

  The problem is that when I use the macname/volumes/dir/folder/folder/file.indd path (which was created from variables) that myFile script is not conclude to the existence of a file that I know. All I get is the alert "file does not exist.

  I set myFile as being a string?

  No, set it as follows:

• Check if certain files exist

  Hi all
  
  I wrote a reference guide and I was wondering if I can check if certain files exist on a page.
  If it exists then I can send the user to a page.
  And if not, they will see another page.
  Grateful if someone points me to the right direction.
  
  Thank you
  Karen

  Hello Cognethos,

  You must use the double backslashes in your path of the file reference. Your script is OK except this line:
  If (FSO. FileExists ("C:\Program Files\Common Files\My file.txt Directory\My"))

  It should read this:
  If (FSO. FileExists ("file.txt C:\\Program Program Files\\My Directory\\My"))

  The technical reason for this is that there are special characters that you cannot use directly in a string. In this case, your path is the chain. Backslash is be one of the special characters that you cannot use directly in a string. To work around this problem, you must do what is called an escape sequence. In this case, the escape sequence for------is------.
