How to delete hidden files?

I am trying to delete two hidden files and have copied the given prompts exactly into Terminal and all I get is files not shown. 

Files have permissions associated with them and if they are not yours, then you can't delete them without elevating your permissions level to do so.
System files are hidden and have special permissions for a reason, so you don't tamper with then and wind up messing up your machine.
Some files, even if deleted, are immediately rebuilt if a system process or program needs it, some are regenerated upon launching or rebooting the machine.
Some files deleted cant' be recovered at all and may cause the machine not to boot the next time.

The files may not exist at the path given, you entered it wrong, the instructions might be for another operating system or version of OS X and the files are no longer there.
What exactly are you trying to do?, what operating system and what hidden files are you trying to delete?
We can correct your perhaps misguided advice, or find a easier solution to your problem or tell you it won't work and why.
but we need to know more please.
If you don't want to tell us, then install the free TinkerTool and enable invisible files and you might be able to delete them manually, however if they are system/root files then your going to need to enter the Admin password for a "sudo" window of root power level destruction. At your own peril! Backup your data now before it's too late.
Good Luck

  • How to delete hidden files that I uploaded to Download folder

    I read posts on delete but am concerned I'll mess something up - I have never used Terminal and am hoping there's an easier way.
    I recently switched from Windows to Mac for my development computer.
    I wanted to edit an .htaccess file for a web site I downloaded it to the downloads folder and of course, because it has a dot as the first character it turns out I can delete it. I was able to edit the htaccess file with Fetch, saved it to a web dev folder and upload it. But I still have an .htaccess file in my Download folder that I would like to remove.
    What is the easiest way to do this?
    Thank you!

    The easiest way is to tell Finder to show hidden files. Open Terminal and copy this to Terminal window:
    defaults write com.apple.finder AppleShowAllFiles TRUE && killall Finder
    Then, go to Downloads folder and delete the file. Finally, return to Terminal and copy the same text but replacing TRUE for FALSE.
    Alternatively, if you know the name of the file, you can move to Downloads folder in Terminal with the cd command and use the rm command to delete the file, but it's dangerous. Don't do it unless you are sure what you are doing, and make a backup

  • USB/SDcard deleted/hidden files

    Hi All
    I realised myself quite recently that files that were 'deleted' on a USB stick were still taking up space on the USB dongle. Anyway it didn't occur to me to empty the trash because 'windows' doesn't work like that, until that is I read some of the other posts.
    Even so when USB dongles or SD cards that contain or have contained 'deleted' files I've seen that the iMAC has inserted new folders on the external dongle/SD called .Trash & .Spotlight. I only saw these folders & their contents when the dongle/SD card was connected to a Cyclone Micro Media device. This explained why the Cyclone doesn't recognise these 'deleted' photo JPGs & stops the slide show i.e. because they have two dots in the filename (eg .IMAGE001.JPG) which the Cyclone doesn't like.
    Sorry to whitter on ... my questions are:
    +- can the Mac OS display files that are hidden (as you can do on windows) in the Trash (or elsewhere for that matter)+
    +- why doesn't the Finder display of the Trash identify the full path name - by that I mean identify the actual device that holds the 'deleted' file. It doesn't seem to me that the 'deleted' files on a particular device can be identified from the list? or havn't I found the method yet?+
    +- would dropping into unix reveal such information and could you then delete the 'deleted' files held on a specific external device?+
    thanks -- keith

    HI red4vr,
    welcome to the forums.
    http://osxdaily.com/2009/02/25/show-hidden-files-in-os-x/ explains how to hide/show hidden files in the finder. As well as how to list hidden files in the terminal, and in the save/open dialog box. There are lots of hidden files on the computer that you should under no circumstance try to delete. A good rule of thumb is if you didn't make the folder, or what's in the folder; don't delete it. don't rename it, don't move it.
    If this is some thing you want to do on a regular basis you may want to use a program like 'blind." http://www.macupdate.com/app/mac/22495/blind this program adds a tool bar button to hide/show hidden files.
    You are correct about the trash can, it shows every thing (not counting hidden files) in the trash for all the drives connected. If you want to tell what is on a specific external volume. You can goto that trash folder.
    ie: finder, menu bar, go menu, goto folder, /volumes/NameOfVolume/.Trash
    Have a great new year

  • Question:  why isn't how to delete a file available.

    How come you have to search for the information on how to delete a file from Adobe Reader.   This should be in the instructions on how to use with how to download.  Does anyone agree?

    If it is a system file and even if the file is corrupted, it cannot be deleted.
    Try reinstalling phone software using Nokia suite if the phone supports Nokia suite and an USB port.

  • How to delete the file with space in name

    Hi
    I want to delete the file "test ex.txt" file.
    i run the following command in command prompt.i can delete the file successfully.
    /bin/rm -f /mnt/"test ex.txt"
    I want to run the command from java.So i am using the following code
    String cmd = "/bin/rm -f /mnt/\"test ex.txt\"";
         Runtime rt = Runtime.getRuntime();
    process = rt.exec(cmd);
    The file was not deleted.
    How to delete the file with space in name?
    Help me

    Use the form of exec that takes an array of command + args.
    arr[0] = "/bin/rm"
    arr[1] = "-f"
    arr[2] = "/home/me/some directory with spaces";Or use ProcessBuilder, which is the preferred replacement for Runtime.exec, and which Runtime.exec calls.

  • How to delete recent file history in adobe reader in Mac PC ?

    How to delete recent file history in Adobe Reader in Mac PC ?
    In Adobe Reader - Edit - Preferences - select Documents in the left panel and change the "Documents in recently used list" to 0. Yes ! the file history is gone But when you set back the value, you will see the file history again. This is not the way to do...
    I have checked all the preference or setting. I couldn't found any clear recent file history in adobe reader.
    Please help ! Thanks !

    First off, you CANNOT set recent documents to zero. The absolute minimum it will accept is 1. And on my MacMini, (I just checked it to be 100% sure) I opened seven documents with Recent Docs set to 10 - they were ALL listed. I set it to 1 and all but the most recent cleared. I then closed Reader and reopened it. The list was 1 item. I reset Recent Docs to 10 and there was still only 1 item in the list.

  • In adf,how to delete a file generated on server,when the webpage is closed

    Hi,
    I have an application consisting of 2 pages. in the 1st page i will give some input details and when i click on submit, some java code is getting executed in the back. That java code generates a csv file in the server location. after succesful execution of java code, i was redirected to 2nd page. In 2nd page, i am giving option to download and when the user clicked on download button and after the file is downloaded -- in the backend i am deleting the file from the server. Till this point everything is fine. But if the user didnt click on the Download button and instead if he closes the browser, the csv file gets remained on the server itself. This is the issue i am facing .. I am not able to get an idea in ADF Framework, how to delete a file when the browser is closed. Please help me out in this.
    Thanks in advance !!!

    ADF has nothing to do with tracking browser close buttons. What you can do is call a JS function and call the method which deletes the file from within the JS function. ADF has a component for calling java code from JS call.

  • HOW TO VIEW HIDDEN FILES?????

    i have searched for days on my computer for some hint a program or option that allows me to view any hidden files in an application folder, but it has yet eluded me.
    I am having trouble with a program of mine, and the tech service there told me to send them the programs log file, which they named. i looked in the applications folder, and the only files i saw was the program icon, and the uninstall folder, which contained the uninstall icon. i told them this, and they replied:
    "i'am sure that these files are on your computer. Maybe they are invisible.
    Please search (automatic) the folder ".********" ."
    if anyone knows, eitehr what this means, or how to view hidden files, please let me know
    Thanx

    To see inside an application package select the application then CTRL- or RIGHT-click and select Show package contents from the contextual menu. You can navigate through the application package's content. It's unlikely you will find anything useful there.
    To see invisible files open the Terminal application in your Utilities folder and at the command line prompt enter or paste the following command then press RETURN:
    defaults write com.apple.finder AppleShowAllFiles TRUE
    To turn off the display of invisible files substitute FALSE for TRUE in the same command line.
    Invisible files are invisible for a reason - to hide them from the prying eyes of novice users and ignorant tech support people. Perhaps it would be more helpful if you could detail the problem you are having.

    defaults write com.apple.finder AppleShowAllFiles TRUE && killall Finder
    After doing it, you will be able to see hidden files through Finder in all the volumes connected to the MacBook Pro
