How do I determine if a file exists or not on my PC?

I thought this would be an easy one and maybe I am just making it harder than what it has to be. I simply want to search in a given directory to see if a file exists on not on my hard drive. Are there any ideas as to how to do this without causing an error if the file does not exist?

Hi:
In those situations what I've done till now is opening  the file
and  close it inmediatly, if I find out and error while opening it
I guess it doesn't exist. I know this is not the best way since there
may be other reasons for the Open File Function to fail, but it has
worked for me. Does somebody know a better way to do it?

    Use Workbooks.Open(...) method which takes the XLS file path
    to open. It returns a reference to the Workbook object if succeeded.
    Otherwise this action raises a COM exception. Sorry but I don't
    know how to handle COM exceptions in a general way. (I think
    the Error Out control may report an error if failed.)

  • How do I determine if my file system is case-sensitive before I buy Photoshop CS5?

    How do I determine if my file system is case-sensitive before I buy Photoshop CS5? I currently have Mac OSX 10.5.8 with an Intel Core 2 Duo Processor and 4GB of Memory.. Adobe says the following requirements are needed..
    2GB of available hard-disk space for installation; additional free space required during installation (cannot install on a volume that uses a case-sensitive file system or on removable flash storage devices)
    1024x768 display (1280x800 recommended) with qualified hardware-accelerated OpenGL graphics card, 16-bit color, and 256MB of VRAM
    Some GPU-accelerated features require graphics support for Shader Model 3.0 and OpenGL 2.0
    I don't know if I have a "hardware-accelerated OpenGL graphics card" or "256MB or VRAM".. I've never heard of "VRAM" before and the last bullet points is just as confusing. The last thing I want to do is buy this program and discover my Mac Book is just a tad bit to old for it, I've already done that once with a video game.

    Disk Utility highlighting the drive or partition & clicking the blue Info icon may report it, but since I don't have Case Sensitive I can't tell for sure.
    A simple test would be to save a small txt doc as...
    test
    Then save to the place same as...
    TEST
    If both show on the Disk, then it is, if it asks to replace test with TEST then it isn't.

  • How to test an image file existing or not

    Hi Everyone,
    I want to test whether an image file exists or not before setting the url of an image component in JSF to it. Following is my code:
    File testFile = new File(image_path + "/p1.jpg");
    if(testFile.exists()){
    info("file exists");
    }else{
    info("file not exists");
    this.myImage.setUrl(image_path+"/p1.jpg");
    Althoug the p1.jpg can be linked to myImage, the existence test always fails. That is, I got the message "file not exists" even though it is already displayed.
    What did I do wrong?
    Thanks in advance,
    Message was edited by:

    File testFile = new File(image_path + "/p1.jpg");Is image_path an absolute path or relative path?

  • I recently updated the iOS on my ipad 3 and lost all my files in the process. How do I recover my lost files which were not previously backed up?

    I recently updated the iOS on my ipad 3 and lost all my files in the process. How do I recover my lost files which were not previously backed up?

    If you don't have them backed up somewhere, then there's little possibility of recovering them. There are some utilities that can in some cases recover an inadvertently-deleted photo, but I've found none that can recover photos or other data from an iPad that was erased as part of an iOS upgrade. You can do a web search for something like "iPhone photo recovery" and you'll find some utilities you can try.

  • File.exists() is not accurate on smb2 network share (use WatchService?)

    Hi,
    According to this document: SMB2 Client Redirector Caches Explained File.exists() is not accurate on a smb2 network share. I am not able to change any register settings, so I want to deal with it. According to the document there is an API to get the notifications from the file system. I assumed that the WatchService is the Java implementation of this API. Am I correct?
    I started with the WatchDir example from the jdk samples and stripped it a bit. I only need to know when a file is created and delete (I don't care about file modifications). For testing I have added new File.exists() when a new event has been triggered. I also start a separated Thread which test the file existence also. When I don't start this separated thread the file exists returns true immediately. When the extra thread is started it is not accurate any more. I need a more accurate file.exists check in the whole application and all running threads.
    The output for my test case is this:
    FileExistsThread: subdir\test.txt == false
    watch registered for dir: subdir\
    FileExistsThread: subdir\test.txt == false
    FileExistsThread: subdir\test.txt == false
    FileExistsThread: subdir\test.txt == false
    FileExistsThread: subdir\test.txt == false
    FileExistsThread: subdir\test.txt == false
    FileExistsThread: subdir\test.txt == false
    WatchDir event: ENTRY_CREATE: test.txt
    WatchDir: subdir\test.txt exists == false
    FileExistsThread: subdir\test.txt == false
    FileExistsThread: subdir\test.txt == false
    FileExistsThread: subdir\test.txt == false
    FileExistsThread: subdir\test.txt == false
    FileExistsThread: subdir\test.txt == false
    FileExistsThread: subdir\test.txt == false
    FileExistsThread: subdir\test.txt == false
    FileExistsThread: subdir\test.txt == false
    FileExistsThread: subdir\test.txt == false
    FileExistsThread: subdir\test.txt == true
    FileExistsThread: subdir\test.txt == true
    FileExistsThread: subdir\test.txt == true
    FileExistsThread: subdir\test.txt == true
    As you can see the file test.txt  is created on line 9. The FileExistsThread have seen it on line 20, (at least 10 x 300 ms later).
    For testing I have used 2 Windows 7 pc's (with smb2 enabled which is default). The working directory must be on the remote pc and the file test.txt must be created (or copied from another folder) on the remote pc (not using the network drive, but on the pc itself).
    Here is my test code:

    If you donot have access to note 45172.1 as specified by Laurent Schneider.
    Snippet from note
    a. Mapped Drive : To use a mapped drive, the user that the service starts as
    must have setup a drive to match UTL_FILE_DIR and be logged onto the server
    when UTL_FILE is in use.
    b. Universal Naming Convention : UNC is preferable to Mapped Drives because
    it does not require anyone to be logged on and UTL_FILE_DIR should be set to
    a name in the form :
    \\\<machine name>\<share name>\<path>
    or
    "\\<machine name>\<share name>\<path>"

    What OS? The trick is to use a known special file that always exists in every folder. On Windows an example of this is NUL. It's the equivalent of /dev/null but exists in every directory automagically. That means you can do this:
    SQL> create directory temp as 'C:\TEMP';
    Directory created.
    SQL> select dbms_lob.fileexists(bfilename('TEMP', 'NUL')) from dual;
    DBMS_LOB.FILEEXISTS(BFILENAME('TEMP','NUL'))
                                               1
    1 row selected.
    SQL> create directory test as 'C:\NOTREAL';
    Directory created.
    SQL> select dbms_lob.fileexists(bfilename('TEST', 'NUL')) from dual;
    DBMS_LOB.FILEEXISTS(BFILENAME('TEST','NUL'))
                                               0
    1 row selected.

  • How to check if a specific file exist and which exit code to use ?

    Hi, First I'm not a scripting guy and I know almost nothing about VB scripting.
    I have a deployment of 6 tasks and I want to make sure that step # 2 will not be process if it failed in step #1, and so on for the 6 task.
    To do this, i have to run a vb script before installation or uninstalltion on each steps
    I'm trying to use a script (not from me) that i have modified for pre-uninstallation of software and also post-installation of the software.
    Pre-uninstallation: The script will look if the specified "exe" exist on the server and if so, than it will run the msiuninstall "application_name".
    If the uninstallation is successful, the post-installation script will check if the "exe" file exist again on the server, and it shouldn't find it (because it was deleted from the uninstallation), than it will return an exit code of successful
    to run the next process.
    Here an example:
    Step 1: Uninstall "Software#1" with msiuninstall Software#1.exe command
    Step 2: Uninstall "Software#2" with msiuninstall Software#2.exe command
    Step 3: Install "Software #3"with an .exe extension
    Step 4: Re install "Software #2" with an .msi extension
    Step 5: Re install "Software #1" with a .msi extension.
    Step 6: Send email to confirm the deployment is successful
    So i need to validate that step #2 will not process step #3 if it failled on # 2. It need to validate if the file exist before and after.
    At the end, Step 6 should send an email to confirm that the 6 steps of the deployment was completed without errors.
    Any idea how to do it ?
    Many many thanks for all the help !
    A desperate guy :)
    This is what i have
    'This script will look if an .exe file exist for a specific application.
    '=============================================================================================
    path = WScript.Arguments.Item(0)
    set objFSO = CreateObject("Scripting.FileSystemObject")
    If objFSO.FileExists(C:\Inetpub\wwwroot\Enterprise\EnterpriseWS\web.config) = true then
        exitCode = 0
    else
        exitCode = 1
    End If

  • How to test if a image file exists???

    Hi ppl,
    heres my problem...im using servlets and jsp and i only ever want to access the jsp file from a redirect in the servlet. Problem arises however if the user trys to access the jsp file directly in which case all the relative links on the page are no longer in the same context as if they were accessed via the servlet.
    i wanna have some kind of test on my jsp page which displays an error page if the user has access the page directly but im not sure the best way to go about this.
    i was thinkin about tryin to determine if an image file exists using a relative link...in which case if the relative links where off then it wouldnt.
    Any suggestions on the best way to do this...or if there might be a better way to test such a case?
    any advice much appreaciated.
    Mycall

    I would suggest moving all jsp's that you dont want the user to have direct access to under the WEB-INF directory. This way they would only be able to access it through your servlet.
    Hope this helps

    By using sp_cmdshell we can know whether files are there are not but in case of my scenario i want to know the directory(folder) is existing or not because the source folder may be blank so it will not get the files there so stored procedure returning the
     File Not found as output.
    following is the code i am trying to retrieve this please suggest any other way to solve it.
    Create table #tableExists  (isValid varchar(255))
    Declare @path varchar(255)='DIR "C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA "/B'
    INSERT INTO #tableExists 
    EXEC xp_cmdshell @path
    select * from #tableExists
    Regards,

    You can try the other two undocumented extended stored procedures as well:
    --EXEC master.dbo.xp_subdirs @pathName
    EXEC Master.dbo.xp_fileexist @pathName
    EXEC Master.dbo.xp_DirTree @pathName,1

    when the user registers with his email id, it will mails him the password and first time it will automatically login(default login) to the application with out asking for username and password.
    here i am sending mail to the given mail id. here i am not able to find the email was delivered or not. if i get to know that ican display registratin fails on the page with put default loginIt's best do it the way pbrockway2 suggested:
    Or you could send some mail to the id containing a link which, when followed, completes the registration process. If the recipient doesn't mail back, have the registration fail. So you ask the user to enter his/her email id. Send an email with the verification link and/or key. Tell the user to check their email and either click the link or enter the registration key in some form. Once that is done, you mark their email address as verified and email them their username/password (personally, I dislike it when sites mail me my password. It's an insecure medium and there is no need for me to see my password when I've just registered, I just would like an option to reset it, that's all). Don't send a mail with the username/password before you've verified the account. What if the user misspelled the email id? The username/password could end up with someone else. And since most people use the same username and password everywhere, you'd be exposing their details to a stranger.
