Recuva and other utilities can scan a hard drive for deleted files and allow you to recover them. Recuva, made by the developers of CCleaner, is a good option.

Windows doesn’t include a built-in tool that scans your hard drive for deleted files, but there are a wide variety of third-party tools that do this. If you try to recover a file by installing a file-recovery program on the same hard drive, the installation process and normal use of the hard drive can overwrite the file. You should try to use the hard drive as little as possible: The best way to recover a deleted file from a hard drive is powering the computer down immediately after the file is deleted, inserting the hard drive into another computer, and using an operating system running on another hard drive to recover it.If you want to be sure you can recover the file, you should perform a recovery immediately. You should recover the file as soon as possible: As Windows continues to write files to your hard drive, the chances of it overwriting the deleted files increases.If you’ve accidentally deleted a file and need to get it back, there are some things you should bear in mind: Image Credit: Simon Wüllhorst on Flickr Recovering Deleted Files

This would make writing to an SSD slower over time. Your operating system erases files immediately to speed up write performance in the future – if it didn’t erase the file data immediately, the flash memory would first have to be erased before being written to in the future. Essentially, data can’t be overwritten onto flash cells – to write new data, the contents of the flash memory must first be erased. When you use a TRIM-enabled SSD (all modern SSDs support TRIM), deleted files are removed immediately and can’t be recovered. Solid-State Drives Work Differently: None of this applies to solid state drives (SSDs). If you want to erase a file’s contents when it’s deleted, you can use a “file-shredding” tool – see the last section for more information. To increase performance and save time, Windows and other operating systems don’t erase a file’s contents when it’s deleted. To actually erase the file’s contents, it may take several minutes – just as long as if you were writing 10 gigabytes of data to your hard drive. For example, if you’re deleting a 10 GB file, that would be near-instantaneous. In contrast, actually erasing a file by overwriting its data takes significantly longer. Deleting a file’s pointer and marking its space as available is an extremely fast operation.

If you’re wondering why your computer doesn’t just erase files when you delete them, it’s actually pretty simple. Image Credit: Matt Rudge on Flickr Why Deleted Files Aren’t Erased Immediately Note that this doesn’t apply to solid-state drives (SSDs) – see below for why. If the file has been partially overwritten, the file recovery program can only recover part of the data. A file recovery program can scan a hard drive for these deleted files and restore them. However, until Windows actually writes new data over the sectors containing the contents of the file, the file is still recoverable. From the file system’s point of view, the file is no longer present on your hard drive and the sectors containing its data are considered free space. When you delete a file, Windows removes the pointer and marks the sectors containing the file’s data as available.
