How to search for names of files in a folder

I've been searching this for awhile and haven't found anything so,I have a game and a game map editor or what not.. and you know when a user clicks on what map they want and such, but how can I search the files inside of a folder? I found JFileChooser but I don't really want to use that because it just wouldn't be right ... so any help would be nice, a link to somewhere, or another word to try and search
thanks

Look at the File API...
list() or listFiles() methods will return an array with every file and directory within a directory.

  • Working on a script to search for and move files - need Guru help!

    Hi, I'm trying to help my dad with a task and my outdated Applescript knowledge isn't helping me much.
    Here's what I need to do in a nutshell:
    FolderA contains a bunch of JPG files.
    FolderB is the root of a hierarchy of folders containing DNG files.
    Each file of FolderA has a mating file (same name but with .DNG) somewhere in the hierarchy of FolderB.
    The goal is to move each JPG file from Folder A to the folder containing it's mate.
    So, the basic flow is:
    1. Get list of files in folderA
    2. Looping through list, strip out file name (fileA) and find the DNG file somewhere inside FolderB
    3. Get the path of the folder containing the matching DNG file
    4. Copy/move FileA to the folder.
    5. Loop back to #2
    OK, so here's where I am:
    tell application "Finder"
    set JPEGfolder to "Macintosh HD:DadTest1:DadA"
    set DNGfolder to "Macintosh HD:DadTest1:DadB"
    set a_list to every file in Afolder
    repeat with i from 1 to number of items in a_list
    -- Everything happens within this loop
    set a_file to (item i of a_list)
    set fileInfo to info for a_file
    set theName to displayed name of fileInfo as string
    -- now theName contains the actual file name minus the extension
    At this point I don't know how to search for the mating file using Applescript. If I was in UNIX I could do a "find . -name filename" and parse out the path, but I don't know how this works in Applescript.
    I think I can figure out how to move the file once I have the path, but the search routine has me stumped for now.
    Any thoughts?
    Thanks!

    In my opinion your best bet is to take a 180° turn and simplify things significantly.
    Your current approach involves multiple file searches - for each file in the JPEG folder, search all the DNG folders looking for a match. That's an large number of searches, and a large number of something that AppleScript isn't great at.
    Instead you'd be far better off walking once through the DNG folders. For each DNG file look for a matching JPG file in the one folder that contains JPEGs. This would be exponentially faster - one walk through the filesystem vs. one walk through the filesystem for every JPEG.
    This should give you an idea of what I'm talking about (untested):
    global JPEGfolder
    on run
      set JPEGfolder to alias "Macintosh HD:DadTest1:DadA"
      set DNGfolder to alias "Macintosh HD:DadTest1:DadB"
      processAFolder(DNGfolder)
    end run
    on processAFolder(theFolder)
      tell application "Finder"
        repeat with eachItem in folder theFolder
          if class of eachItem is file and name extension of eachItem is "dng" then
            set basename to characters 1 through -5 of (get name of eachItem)
            try
              move file (basename & ".jpg") of folder JPEGfolder to folder theFolder
            end try
          else if class of eachItem is folder then
            my processAFolder(eachItem)
          end if
        end repeat
      end tell
    end processAFolder
    The idea here is that you start off in the top folder and iterate through each item. If the item is a file and it's name extension is DNG then try to move a corresponding file from the JPEG folder to the current folder. This is wrapped in a try block so the script doesn't fail if there is no corresponding JPG.
    If the current item is a folder then the script descends into that folder by calling itself.

  • How to SEARCH for specific file TYPES, e.g. PDF?

    If I know the title has in it "resume" and I know it's a PDF, how do you search for all PDF files that have the word "resume" in the title?
    AND..
    How would you search all PDF files that had the word "supervisor" inside the document?
    Thanks

    Command F should do it. Once the search window appears, you should see a drop down box headed kind and next to it one headed any. Select PDF from the any one. Click the plus button, and another field will appear and you can see again more drop down boxes. You just want to set these up so you end up with name and contains, you can then add your text to the remaining field.

  • Please answer. how to search for files

    Hi,
    We need an integration with SAP. They send us files in the format: yyyymmddhhmiss.atv
    For example we receive following files:
    20050503101115.atv
    20050504101115.atv
    20050505101115.atv
    So, we dont know how to search for all files with extensions ".atv" in the directory.
    We are using PLSQL. Is there some way to resolve with UTL_FILE?
    Any other suggestion?

    A possibility:
    In sqlplus, issue a HOST command to list the files to a file:
    ls *.atv &gt; atv_dir.txt
    Then use utl_file to read atv_dir.txt and parse it for the file names.
    You could put the filenames in a pl/sql table and use that as loop control.

  • In iTunes 11.0.2.26, an Albums search by track names returns albums as if they only have one track on them, but I still want to access the entire album. How can I have the search results show the entire album (with just the searched for name highlighted)?

    Hello, all.
    In iTunes 11.0.2.26, an Albums search by track names returns albums as if they only have one track on them, but I still want to access the entire album. How can I have the search results show the entire album (with just the searched for name highlighted)? For instance, I'm wanting to play an album with a particular track on it or I'm searching for albums that include that track. iTunes incorrectly assumes that all I'm after is that one track and then incorrectly displays the album as if there is only one ttrack on it. This is a bonkers default setting. Can I change this?

    Click the search magnifying glass and uncheck "Search entire library".
    Type in the name of the track.
    Click the album of interest to show tracks.
    Select the track.
    Press the X in the search box to clear the search.
    Double click the track you want to start playing first.

  • How to search for a certain cross reference using its name in FM 11?

    How to search for a certain cross reference using its name in FM 11?

    Well, thank you. I am only using Find dialog box. By "name", I'd like to give an example. The background is FM 11 structured. I have an element "xref" which is used to make cross reference. Now In Chapter 1, there is a sentence like "This is an ODU for ...". I made a cross ref of the word "ODU" to its full name "outdoor unit" in Chapter 2 (in the same book). After this, the word "ODU" in the sentence in Chapter 1 will no longer be a plain text. So I no longer can use the find dialog box to search for "ODU" because it is already an xref rather than text. I am not if it's clear.

  • How Can I stop Elements 7 from searching for a memory file?

    Recently, every time I turn on Elements 7 it starts searching for a missing file each time it encounters a photo with a "?" in the corner. I must have pressed a key somewhere to start this function but now I can't get it to stop. I can only continue to another photo if I press cancel while it is searching but I have to do this for each "?" marked picture. Is there any way of cancelling this feature? Thanks in anticipation.

    Two solutions:
    1. Uncheck the option Edit > Preferences > Files > Automatically Search For And Reconnect Missing Files.
    2. Either reconnect the missing files or delete them from the catalog, using the File > Reconnect > All Missing command.  See this FAQ for tips on how to use the command:
    http://www.johnrellis.com/psedbtool/photoshop-elements-faq.htm#_Quickly_reconnecting_large
    Leaving missing files in your catalog doesn't have any benefit.

  • When I open iMovie, the app searches for missing iPhoto files.  These are files I deleted.  I have to close about 30 dialog boxes before I can start using iMovie.  How do I make this stop?

    When I open iMovie (09), the app searches for missing iPhoto files.  These are files I deleted.  I have to close about 30 dialog boxes before I can start using iMovie.  How do I make this stop?

    So it seems the issue is when iMovie is wanting to creat thumbnails, if I ask it to ignore then it's fine but if not it hangs up searching for the video file.

  • How to search for a file faster?

    Whether you are searching for a particular file or searching within all the files then putting 10,000,000 file in a single directory looks (to me) to be silly!
    If you just want to find a particular file then why not build an index (say in a simple database). If you want to search within all the files then some directory tree structure will stop Java having to load into memory the whole of your directory content.

  • Searching for a good file manager

    I'm searching for a good file manager. Konqueror 3.5 is quite good, dolphin 4.1 and konqueror 4.1 are not. Since konqueror 3.5 is going to die due to lack of support in the future, I kind of need to find a new good file manager...
    Do there exist file managers with the following features?
    Many of these features are things I thought were quite logical to be in a file manager, but seem to be missing in most "modern" ones...
    -independent of any desktop (gnome or KDE), just a standalone program
    -preferably not being both a web browser and file manager in once, at least not in an annoying way. Konqueror 3.5 shows that being that combination is possible without being annoying.
    -ability to have a tree view of the folders on one side and list view showing the files and subfolders of the folder currently selected in the tree on the other side
    -detailed list view showing at least filename, type, date and size, and the ability to sort according to any of these properties
    -a non-detailed view showing image contents would also be nice, to browse folders of photos or other images
    -ability to open files in certain programs if you doubleclick the file, NOT open it by singleclicking, singleclicking may only select it
    -ability to select multiple files by dragging box around files or using keys like "ctrl" and "shift"
    -ability to do "open terminal here" or type terminal commands in the current open directory
    -must have ability to drag files from one folder to another, from list view to tree view and vica versa, to move or copy them
    -and must have ability to use "ctrl+c" and "ctrl+v" to copy files and foldes from here to there
    -multiple tabs is a huge plus
    -favorites (to local folder paths) is also a huge plus
    -preview of files when hovering the mouse over them is nice
    -must have ability to zip and unzip (or other compression formats) folders by just right clicking them and choosing a zip/unzip command there
    -in addition to that, must also have ability to browse through a zip file as you would through a normal directory, and drag files from the insides of the zip file to the tree view to automatically unzip those files there, and of course "ctrl+c"/"ctrl+v" should also work to copy a file from the inside of the zip file, to some other folder on your disk
    -no horizontal autoscrolling in the tree view, that is an invention straight from the abyss...

    I know exactly how you feel about KDE 4 vs. 3 -- Konqueror was the best part of KDE for me (pretty much the only part I ever used, actually; my window manager is a slightly modified version of WMII and I generally loathe "desktop environments"). KDE 4 ruined it, completely and utterly.
    I submitted about 20 different bug reports about Konqeuror 4, mostly features that they'd deleted or mangled; some of them are starting to be addressed now. I don't think they'll ever fix the speed issues though, because those are dependent on the underlying KDE 4 libraries as far as I can tell -- it's as if KDE 4 were purposely and deliberately designed to be slower than KDE 3. Even if they fix all of its deficiencies, that'll probably keep me from using it...
    Right now there's KDEmod, which will hopefully maintain its KDE 3 branch for a while longer. It's starting to show some problems, though; I haven't been able to get kdemod konqueror 3 to work fully out of the box (the settings pages are all blank). On my main machine, I somehow managed to hack together some of the KDEmod3 packages so that I have a functional konqueror 3 running alongside the Arch repository's version of KDE4. I'm afraid to pacman -Syu now, though, because it will probably break horribly :P
    I don't remember exactly how I got konqueror 3 going like that, as I did it in my initial fit of rage after I did the pacman -Syu that got me KDE4 (a decision I have regretted ever since), but it was something like this:
    1. move /opt to /opt.kde4
    2. make a new /opt
    3. download several KDE 3 packages from the KDEmod3 repositories manually
    4. extract those packages into the new /opt with tar -xzf (NOT pacman!)
    5. try /opt/kde/bin/konqueror
    6. read reams of error messages about missing libraries, segfaults, etc.
    7. try to supply the missing libraries by downloading other kdemod3 packages and manually extracting them
    8. goto 5
    Then, when everything worked (sort of), I renamed some stuff so that 'konqueror' is konqueror 4 (I think having it konqueror 3 broke something else, but I don't remember what), and konqueror 3 is called 'k3nqueror'.
    If KDEmod3 ever goes away and there's no other good replacement file manager by then, I'll probably take the source code of KDE3 and try to make a standalone version of konqueror out of it. (Which will probably be quite a project because of how interdependent all the KDE components are.)
    Some features I "need" in a file manager, besides the ones you mentioned:
    - Konqueror's tree view (where you can expand folder branches in the file list)
    - Infinite view splitting -- I frequently have my konqueror windows split into 4, sometimes as many as 6 or 7 view panes. Very useful for sorting out files.
    - Selection rectangles are sensitive only over files -- I find full-row-select really annoying, because there are no guaranteed "blank" areas that you can click on to clear a selection. I also use this behaviour to grab long-named files that are interspersed with short ones, because they hilight first when the rectangle touches them (you wouldn't think this very useful, but surprisingly often you do want to do something to all the long-named files...)
    - Right-clicking on a folder and clicking "Paste" pastes into that folder, not the current one -- you'd be amazed at how many file managers get this wrong. I shouldn't have to cd into a folder just to paste some files there.
