    Where does all the trash go?

    I apologise is this seems a lame question, but I don’t know much at all about computers; nor have I ever really been that interested.

    However, when the garbage gets full, the garbage truck collects the crap and takes it to a land-fill where some is incinerated and the rest is pilled where upon it eventually gets full. What happens to all the deleted info when you empty the trash bin? Seriously, I’m curious.
    You bullied, you laughed, you lied, you lost!

    It sits there for a week or two in case the mods need to check anything and then it gets deleted.

    You said it yourself it gets deleted! Don't think of files as something physical their not. Think about a file as the same as a pencil drawing, when you create a file the computer draws it, when you delete the file the computer just rubs it out same as you would a with a rubber on a pencil drawing.

    your file is just a whole lot of numbers that are stored in their binary representation. so your hard drive for example is a vast array of binary bits that can be on or off ( 1 or 0 ).- these blocks of binary data are organised by your file system - it keeps a record of where your data is in the the vast array , simplistically , the address in the array where it starts and where it stops - so all the on and off bits between are then fed through the program whose job etc is to interpret that file type.

    when you delete you are basically telling the file system organiser that those bits are now free to be used again , so the bits are still there until they get used again - overwritten.
    If you torture data for enough time , you can get it to say what you want.

    Thanks for the explanation. If that's the case, then how do special authorities for instance retrieve information that has already been deleted and pressumably over-written? Not that i have anything to hide of course.

    if it has been overwritten - and normally to scrub a drive you will use a program that will write all on's (1's) or off's(0's) or random to every bit on the drive.

    certain security specs say that it has to be done a number of times , 3+

    there have been articles , and maybe proof on concepts that say that by examining the disk platter molecules they can determine previous states of the sectors of the disk which is why some require multiple write passes over the entire disk to ensure it is scrubbed clean.

    if your data is encrypted correctly it really wouldn't matter.

    there are always articles on geek news sites about data storage devices being bought second hand online - ebay etc -that still contain secret military data or bank numbers etc.

    encrypting your data is the best way to secure it.

    Just clicking the delete button on your pc recycle bin doesn't delete anything, it just tells windows that it can be over written if it needs to be, with the size of hard drives these days most stuff never gets deleted.

    Because they are separate things. As said, when you use your computer to "delete" a file, all that gets take off is the bit of code that tells the computer where to find the file. The actual data is still there. And it stays there until, by chance the computer decides to use that sector of the disc for storing other information (nd over writes).

    If you use a program that looks for the actual data (rather than simply the address of where the data is) it will find it with no problems.

    As noted, to be SURE of deleting, you are advised to overwrite the specific sector many times (some programs default at 7 times I believe).

    A good free program for keeping registery in check, startup, and encrypted shredding is Glary Utilities. You right click and shred the documents. It will overwrite the file using Department of Defense encryption standards.
    Use the recycle bin for regular stuff and shred the files you want to disappear forever.
