So the thing is that your operating system doesn't completely erase files right after they were deleted. In reality the space freed is marked as available, but the files are still there somewhere. That is why after the files were deleted you have to really act as fast as possible before they get overwritten. Ideally you should stop using the hard drive, connect it to an external docking station, and boot from a different system drive or machine. Then connect the drive where you lost the data.
Disk Drill has the top knowledge about the Recycle Bin recovery. And don't forget that you can even get a free Recycle Bin recovery, as Disk Drill Basic for Windows lets you restore up to 2GB of data for free.
The best free Recycle Bin recovery method is protecting your files in advance with Disk Drill for Windows. It offers a simple genius Recovery Vault method so that you never lose any files again. This method works on FAT32 and NTFS. With Recovery Vault enabled all your deleted files are thoroughly tracked and whenever you see the important file is missing, just go to "Undelete Protected Data" option of Disk Drill.
We all know these days computers are super fast and there is so much activity going on in the background that the file allocation tables are updated frequently. This way your deleted files may be pushed out of the stack and won't be found by a regular scan. Use Deep Scan for such situations. Disk Drill goes through your hard drive byte by byte to reconstruct every file. It knows so many file types that it can recover pretty much anything. Deep Scan will take longer time, but is such an effective method that it is worth the wait.
