Problem with deleting files !!

I want to delete file, but for some extensions it is not possible, how can I delete all files?
I use
myFile.delete();

How about the return value from your delete call, is it "true"? What happens when you try to delete the file via your OS? Why do you seem to think that this behavior is specific to certain file extensions? Which extensions are you having trouble with?
Sorry for all the questions. Just as a guess, I think the most common reason for a delete call not to work on a Windows box is because the file is in use by some other program - an editor, or maybe a web server. Trying to delete the file via the OS might give you a better idea of why it's not deleting.
good luck

  • Problem with deleting files from new Zen St

    I recently bought a Zen Stone and today needed to delete some files. Did this from Windows (like with my Zen Nano), but this did not free any space on the Stone.
    Went to browse files (albums) on Stone and found several names that did not show up in either a Windows Explorer or Media Lite search.
    Apparently when I deleted the old files, they did not actually get deleted (guess I have to use Media Lite to do this)
    Any suggestions as to how to remove these files without reformatting?

    If you want to preserve the data on the boot drive, you must try to back up now, before you do anything else.
    There are several ways to back up a Mac that isn't fully working. You need an external hard drive to hold the backup data.
    1. Boot from the Recovery partition or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
    2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

    I think the real problem is that you don't check the return value from read (it's probably less than data.length indicating an incomplete read). Isn't there a readFully somewhere?

  • SFTP MGET of large files fails - connection closed - problem with spool file

    I have a new SFTP job to get files from an FTP Server.  The files are large (80mg, 150mg).  I can get smaller files from the ftp site with no issue, but when attempting the larger files the job completes abnormally after 2 min 1 sec. each time.  I can see the file is created on our local file system with 0 bytes, then when the FTP job fails, the 0 byte file is deleted.
    Is there a limit to how large an ftp file can be in Tidal?  How long an ftp job can run?
    The error in the job audit is Problem with spool file for job XXXX_SFTPGet and an exit code of 127 (whatever that is).
    In the log, the error is that the connection was closed.  I have checked with the ftp host and their logs show that we are disconnecting unexpectedly also.
    Below is an excerpt from the log

    I believe there is a limitation on FTP and what you are seeing is a timeout built into the 3rd party application that tidal uses (I feel like it was hardcoded and it would be a big deal to change but this was before Cisco purchased tidal)  there may have been a tagent.ini setting that tweaks that but I can't find any details.
    We wound up purchasing our own FTP software (ipswitch MOVEit Central & DMZ) because we also had the need to host as well as Get/Put to other FTP sites. It now does all our FTP and internal file delivery activity (we use it's api and call from tidal if we need to trigger inside a workflow)

  • [SkyDrive] Files can't be uploaded because there's a problem with a file or folder.

    On Windows 8.1 RTM, the SkyDrive metro client shows a message that "Files can't be uploaded because there's a problem with a file or folder." and lists one particular file. When I installed the PC, I have switched then Access all files offline
    option to On.
    The file resides in a directory I have deleted from the disk. When attempting to get rid of this "problem" (as there are no hints nor UI available) I have manually checked that the directory does not exists on the disk any more, as well as deleting
    the directory from cloud storage using a web browser. However, the message is still there.
    Restarting the computer several times nor keeping it idle for a significant amount of time did not help.
    How to get rid of that "problem" / how to fix it?

    Hi
    Let’s try to redirect the skydrive folder and sync again to see what’s going on:
    1. Open regedit and find following key:
    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\SkyDrive
    2. Change “UserFolder” to another location.
    3. Open the SkyDrive Metro app to confirm your files and new directory.
    Then check the issue again.

  • Have a problem with deletting a folder that has lots over 100+ folders in it that are locked, please help

    Have a problem with deletting a folder that has 100+'s folders in it that are locked. Please help.

    Put the folder into the trash - go to the Finder menu and hold down the alt key whilst selecting Empty Trash.
    I've never tried this with a folder full of locked files, but it certainly works with a single locked file.
    Hope that helps!

  • Problems with .ARW files and auto toning

    problems with .ARW files and auto toning
    let me try to explain this because this has happened in past and never found a way to resolve but i lived with it
    now that I have a Sony A7R the problem is more serious
    Firstly i take pride it making the picture happen all in camera, i use DRO lvl 5 to get enough light, like when i'm shooting at dusk. DRO its like doing HDR but in a single file, it lightens the darks. in my camera i'm happy with results
    but when I upload them to lightroom, they come out near black.
    allow me to explain
    lets say I import 100 images
    i double check my preferences and everything is UNCHECKED when it comes to importing options, there is no auto toning, nothing.
    as the images import i see a preview in the thumbnail which looks fine.
    i double click on one to enlarge it, hence leave grid view.
    for a brief 1 or 2 seconds, i see the full image in all its glory but than lightroom does something funny, it darkens the image
    one by one as it inspects each image, if it was a DRO image it makes it too dark.
    to make this clear, the image is perfect as it was in the beginning but after a few seconds lightroom for some reason thinks it needs to correct it.
    how to prevent lightroom from doing this, i want the image exactly as it is, why must lightroom apply a correction>?
    i think it has to do something with interpreting the raw file and lightroom applies its own algorithm.
    but here is what i dont get.....before lightroom makes the change i'm able to witness the picture exactly as it was taken and want it unchanged..
    now i have to tweak each file or find a profile for it which is added work.
    any ideas how to prevent lightroom from ruining my images and just leave them as they were when first detected...
    there are 2 phases...one is when it originally imports and they look fine
    second is scanning each image and applying some kind of toning which darkens it too much.
    thanks for the help

    sorry thats the auto reply message from yahoo email.
    i've disabled it now
    thing is, there is no DRO jpg to download from the camera
    its only ARW. so my understanding is when i use DRO setting, the camera makes changes to the ARW than lightroom somehow reads this from the ARW.
    but then sadly reverts it to no DRO settings.
    because i notice if i take normal picture in raw mode its dark but if i apply dro to it, it comes out brighter, yet when i d/l the image from camera to lightroom, which is an ARW - there are no jpgs. lightroom decides to mess it up
    so in reality there is no point in using DRO because when i upload it lightroom removes it.
    is there a way to tell lightroom to preserve the jpg preview as it first sees it.
    its just lame, picture appears perfect...than lightroom does something, than bam, its ruined,.
    what do i need to do to prevent lightroom from ruining the image? if it was good in the first place.

    Image files must be sent as byte[] NOT as String ......

    Because i commented the above line & compiled, so it is not giving any error now.

    it's read windows registry value. So, no problem if you comment it.
