(Click any image in this story to enlarge it.) IDGĬardRecovery shows you thumbnails of the deleted JPG images it finds. If the files you're looking for show up early in the deep-scanning process, you can stop the scan and recover the files that the tool has found at that point, saving you time. During its deep-scanning process, CardRecovery shows you a list of deleted files it finds, updating this list as it scans. OS: Windows 98 and later (CardRescue available for macOS)Īlthough it can be used on USB flash drives, CardRecovery was designed mainly to recover audio, image and video files from memory cards used in cameras, so it will not search for other file types like office documents.ĬardRecovery does not do surface scanning it only deep scans. No other applications were running when each recovery tool was running, nor was the laptop connected to the internet or other network. This notebook was selected to gauge how well these recovery tools perform on a modern-day Windows computer with minimum specs. It had an Intel Atom CPU Z3735F running at 1.33GHz, and 2GB RAM. We tested the recovery tools on a laptop running the current version of Windows 10 Home, 32-bit version. Next, each was tested for its deep scanning capability on the USB flash drive. (Some of these products also offer versions for other platforms, which we didn't test these are noted at the top of each review.) Each tool was tested to see how effectively it could surface-scan the flash drive to find and restore all of the deleted files, their filenames, and folders. We tested the Windows versions of these file recovery apps. After these files and their folders were loaded onto the USB drive, they were deleted from the drive. The two ZIP archives were not put into folders on the flash drive. Sixteen of these files were sorted into three folders (Documents, Media, Pictures). It was formatted as FAT32 and loaded with two of each of the following file types: Microsoft Office documents (Excel, PowerPoint and Word), images (JPG, PNG), MP3, MP4, PDF, and ZIP. In our tests, we used a 16GB SanDisk USB 2.0 flash drive. The range is wide: from several minutes to hours. Basically, it takes less time to deep-scan a 16GB flash drive than one that's 32GB or more. This scan method can take a long time - the time is based on the size of the storage device. Under a deep scan, the recovery tool slowly reads every bit of the storage device, attempting to reconstruct what it recognizes as deleted files among this data. The second method is commonly referred to as a “deep scan.” You only want to do this if a surface scan fails to find the deleted files you need back. But the odds of success lessen if additional files have been saved onto the storage device since then. This scan method will likely result in successful recoveries if the files you want back were recently deleted. Four of the recovery tools in this roundup perform surface scans, and all were able to surface scan the 16GB flash drive that we used for testing in just seconds there was no appreciable difference among them regarding surface scanning. Based on this information, the recovery tool extracts your deleted files from the storage device and saves it to the other storage device you picked to save your recovered files to.ĭepending on the size of the storage device that’s being scanned, this should take only seconds for the tool to do. The first is a “surface scan.” The recovery tool simply locates hidden information on the storage device that points to where your deleted files were originally located on it. There are two ways that a recovery tool can scan for your deleted files. In this case, your recovered files are typically assigned generic, sequentially numbered names by the recovery tool, so you’ll have to rename them manually. Not every recovery tool is able to restore the original filenames of your deleted files or the folders they were under. Alternatively, the recovery tool may be designed to automatically save whatever deleted files it finds as it’s scanning to the output storage device you selected. It generates a list of deleted files that it was able to find on the storage device, and from this list you pick the ones you want to recover from deletion. Next, you start the recovery tool to scan your flash drive.
