Then it stores a new series of 1.s and 0’s over the old one. Thus, instead of the computer going and erasing all the 1’s and 0’s, it waits until there’s something new to store.

FAT allocates that space as free space, ready to be written over. When you delete a folder or a file and remove it from the recycle bin, all what you’ve done is instruct the FAT to remove pointers to the data. FAT also protects written data so the computer can’t write over used space. FAT organizes all data bits in an orderly fashion. It’s the FAT that tells your computer system where the file is located on the drive.
The saved file is then written on another section called the File Allocation Table (FAT). If the file is too big for one section, the computer may break the file into multiple sections. In SSD and USB drives, the bytes are stored in a series of individual memory cells rather than long bands.įor speed and efficiency, the computer writes the data in the first available space it can find that’s sizable enough to hold the file. These bits of data are written in long continuous bands and saved around the physical hard drive. Your hard disk writes every byte of information you create as a series of blocks represented by 1’s and 0’s. How Does Data Storage Work In The Computer? To understand how deleting data works, let’s first understand how data storage works in a computer. For Solid-State Drives (SSD), the data is removed permanently when you delete files and folders. However, this only applies to regular Hard Disk Drives (HDD). Until your OS overwrites the hard drive sector, a file recovery program can scan, find, and restore the deleted files. Thus, for fast operations, the OS will only delete the pointer and then later overwrite the deleted data with new information.Īs you continue creating new files and folders, the OS overwrites the sections of the hard drive that have no pointers that indicate the existence of data. The reason the OS only deletes the pointer is because it takes much longer to delete a file than it takes to delete the pointer. So the data still exists in a sector of your hard drive, even though the system shows the data no longer exists. To make that file easier to find in the future, move it into a folder in "My Drive.Whenever you delete any file, what you’ve essentially done is delete the tracker pointing to the file. If someone deleted that folder, you won't see that folder in your Drive anymore.įind files you created in deleted foldersįind all files that are in deleted folders If it was in a folder someone else created Contact the person who created the file and ask them to restore it or share it with you again. When someone creates a file, they can delete, rename, and restore it. Search now If someone else created the file
The file isn't deleted, it's automatically moved to your My Drive. You share a folder with someone and they remove your file from the folder.Important: Only you can delete the files you own. It's automatically moved to your My Drive. You create a file in someone else's folder and they delete that folder.The file still exists, but is harder to find. If you can’t find a file that you created in Drive, it might have lost the folder it was in. Learn why files go missing If you created the file For example, to see spreadsheets, next to 'Type,' click the down arrow, then click 'Spreadsheets.' Use the advanced search options to find your file.In the search bar, click the icon to the far right.Click "Activity" to check the activity panel.
