Media application folders do not show up

I just changed the microSD card and put a larger capacity one onto my Curve 8900.
When I checked to the Media application forlders, it only showed one folder, Music folder.
It used to have five forlders; Music, Pictures, Videos, Ring Tones and Voice Notes.
Why did it happen and how to fix it?
Thanks,
Fit

P.SP.  
Not exactly. First you make sure that these directories really exist on the card connecting it to the computer. If they do then they should be indexed after you start/reboot your phone. To do that find the Icon Media, click it. If it goes ok, then you will see the scrolling bar at the bottom of the screen. Wait until it goes away. It can take a long time, say, 5-10 minutes if you use a large capacity card. I'm using 16 GB Class 6 A-Data card, it's extremely fast, almost full, excluding ~100 MBytes or so, and it takes a very long time to reindex it. I guess RIM should fix this issue. If I just reboot the phone it should not reindex the entire database, especially keeping in mind that the media engine creates hidden bb dat files in each directory having media files. So rereading all of them or even better - creating a large file with all these files inside, should be much faster. But ok, we have what we have. Here is one more trap although. If the directory name or the file name is too long, then the entire directory or even the whole branch can fall out from being indexed. As a result you will be able to Explore these files, but they will not be accessible through the Media Manager, which creates the groups of artists, disks, styles, etc., etc. I spetted on these rakes several times and to get the bad file name I had to restart the phone several times, adding my directories step by step to get which one is not accepted. Also keep in mind that if you have other languages installed you will be able to keep the file names in these languages. The same works for MP3 tag info. P.S. I'm waiting for 32GB cards to put my entire library there, 16GB is stil not enough space for it, especially if we add a few video files, even the short ones. Btw, the customer support was not able to answer me what is the maximum numbe of directory levels or the total path/file name length acepted by BB8900. If anyone knows please post this info here.

  • Applications Info Is Not Showing Up in the System Profiler

    My applications info is not showing up in the new system profiler. I get the message "no information found". Any help would be appreciated.

    I'd get them to send you another card.  If it works, great!  If not, then the connection on the computer is bad.  If that's the case, you can get a wireless PCI card or a wireless USB adapter, but the PCI card would be better.  Test it with another Airport card first though.

  • Messages located in sub folders do not show in iPad Mail

    Using iPad mail with Microsoft Exchange sync works great at the inbox level but any messages that are in sub folders do not show up in Mail on the iPad. All of the sub folders show up but do not show messages. In addition, I am not able to collapse the parent folders, the result is a very long list of empty folders. The exception is emails that I move to the folders on the iPad do show up if the folder is selected on the iPad. Looking for solution.

    Has anyone else noticed the following?
    I've synchronized with Exchange and am noticing some odd mail behaviour:
    - I have folders in my PC Outlook inbox
    - when I have mail open on my ipad, and a new message comes in, if I happen to be an a subfolder (example a special folder for messages from my boss or whatever) all the new mail goes to that folder instead of the inbox.
    - even weirder, it stays there when I go back to my PC and Outlook.
    Not very useful long term since I end up with seriously misfiled mail...

  • When switching spaces application menu is not showing

    I'm not sure the is a Snow Leopard specific problem, but I have certain applications assigned to certain spaces. When I switch to a space for that application and it has an open document, everything is fine. But if I close all of the document windows for the application and then switch away from that space and then back to that space, the Finder menu takes over. The application is still running, but I have to either click it's icon in the dock or cmd-tab to the application to get it's menu or toolbars to appear.
    Is this normal behavior? It's kind of a pain to mak sure that I at least have one open document window so that when I switch back to that space I don't have to "reactivate" the app. Just so I make sure i'm explaining this correctly...
    I have Photoshop in it's own space and then open the program and then don't open a document window and then switch to another space and then switch back to the Photoshop space, I now have the Finder's menu displayed and a blank desktop showing. I then have to click on the Photoshop icon or cmd-tab to the running application to get it's menus and toolbars to show.
    Thanks for your help.

    First off, I meant to title this "When switching spaces application window is not showing."
    Just in case anyone else runs into this problem or any other weirdness with switching between spaces, the answer seems to be trashing the com.apple.dock.plist file and then restarting the dock. The preferences file can evidentially get corrupted and create some problems. Spaces does not have it's own plist file but stores it's data in the dock's plist file. Be warned that this will reset all of your dock preferences including which apps you have on the dock.

  • Closing an application that does not show up as open

    I downloaded an application off the internet and it is messing with my computer.  I tried all the ways to delete but it wont because the error message says that it is still open.  however, I cannot close it using the conventional methods including turning off the computer.  it does not show up as open when I use the force quit menu so it will not let me force quit it.  ultimately, I want to delete this intrusive application.

    Name of app?
    Did it come w/a Read Me file?
    Did it come w/an uninstaller?  If so, use it.  If not, go the app manufacturer website for uninstalling instructions.
    Check System Preferences>Accounts>Login Items.  You can disable from there.  Also, there is a mapping location of where the file is.

  • Certain folders do not show in Finder.

    Hello,
    I have a MacBook Pro, OS X 10.9.4 version. Lately my Finder window does not show the files in certain folders in thumbnail view, which is my default use. So, if the folder is in thumbnail view, the files do not show. Only if I change to other views or search file name in Finder search bar, the files show. But it's been a hassle doing this everytime I open these folders. Happens with several folders. I do not really recall if this happened after an incident in particular or a software update, but it's been for almost three months. In case this would help, I overuse my devise and it might happen that I have a couple, sometimes more, of apps as Ai, Ps, InD, and Rhino opened at the same time. My MacBook is also 4 years old, and I have changed my hard drive two years ago. Processor is 2.26 GHz and Memory 2GB 1067 MHz. Any help with that..?
    If this is not the right community, please help redirect.
    Thanks in advance.

    I assume this is the option that you are having the issue with.
    When in this mode, have you clicked on the GREEN button in the upper left hand corner?

  • Application icon does not show up in iTunes - AdHoc distribution.

    I set an icon of size 57 x 57 as the application icon. The icon shows up in the applications list of the iphone. When I bundle it for an adhoc distribution and add it to iTunes, the icon does not show up in the iTunes Application list. But it shows up on the iphone device that I copy to.
    Am I missing something?

    iTunes does not use the icon for display (the icon is only used on the phone itself). In order for iTunes to display the artwork as well, you need to create a 512x512 JPEG file named "iTunesArtwork" (no extension) and copy it into the application bundle (note that you will have to build the application again after this so that the code signature will sign the additional file as well).
    This file should be same (other than the name) you load up to iTunesConnect as the 512x512 artwork.

  • Newly Created Folder Under My Folders Does Not show Up in Answers

    I created a new folder in My Folders using "Manage Catalog". It shows up in the Manage Catalog window but does not appear in Answers even after I refreshed the display. I've successfully created folders in the past, but this suddenly stopped working. The only thing that I had done was rename the Subject Area in the Administration tool. Does anyone have any insight as to why folders created does not show up under My Folder. However, I am able to create folders under Shared Folders.
    Thanks in advance.

  • Downloaded applications/games do not show

    I tried twice erasing and restoring from backup on my son's iPad mini but some applications do not show on any screen but are visible in the "Settings" and also in iTunes and example is "Skylanders Trap Team"
    In the example above I could not download the game from the AppStore, the "download/free" button was disabled.  I was able to subsequently download via iTunes and see that it was sync'd with the iPad, but it is just not visible.
    Please advise as to my next steps.
    Thank you

    Do you have restrictions turned on for installing apps or for age content? Settings>General>Restrictions. If you do, you need to turn those off in order to install apps and have them appear on the iPad.

  • Media Browser in iWeb not showing Photos

    Hi
    I have read through many of the threads on here from people who seem to have the same problem and tried many of the suggestions, but still do not seem to have improved matters.
    I have the message saying that I need to open iPhoto 2 or later. I am running iPhoto 6 and iWeb 1.1.2. I have an iBook G4 with 1GB Ram.
    I know it is nothing to do with the little dot and I have also tried deleting various preference files.
    Does anyone have any suggestions?
    Thanks

    I am having the same problem in Pages 2, Keynote 3, iWeb, iDVD, iMovie ....etc.
    iTunes and iMovie's material will show in the Media Browser in all the above apps. But iPhoto will not. If I move the iPhoto Library to my desktop and open iPhoto it will ask me to build a new library. I do, and in all the above apps I can see iPhoto and the library tree. If I grad some of the picture in the Originals folder on my desktop and put it into the new iPhoto library, it imports them just fine and then I open Pages 2 (Media Browser and there is the iPhoto tree.
    Sounds like a solution right? Nope!
    When I got back and import the rest of the photos from the Original folder on my desktop the Media Browser "loses" or drops the tree and I am left with the Message, "Open iPhoto 2......"
    I then deleted the new iPhoto library, keeping my Originals on the desktop and created yet another blank library, opened Pages 2 or Keynote 3 and again I can see the iPhoto tree.
    I went to my desktop and put one folder at a time into the new library via iPhoto, then open up Pages 2 (Media Browser) and I can see the tree. YEAH! Then I went an put another folder from the desktop into iPhoto and the tree in Media Browser goes away.
    I have found no reason or particular file to be causing this. Does anyone have any suggestions? Is this a Media Broswer error or iPhoto? iWeb?
    Notes:
    I ran the test each time by completely opening and closing Pages and iPhoto. I am running iPhoto 6.0.6 and Pages 2.0.2
    MacBook   Mac OS X (10.4.9)   I
