There are several steps that can be taken to retrieve lost files, including checking the recycle bin, using the backup feature on the computer and using file recovery software. If these steps do not work, a company or individual who specializes in file recovery may be able to help.
The first thing to do when trying to retrieve lost files is to check the recycle bin. The icon for the recycle bin can usually be found on the computer's desktop; however, if you can't find it, simply use the search function and type in recycle bin. If the files are found inside the recycle bin, highlight them, right click on them and select restore. The files can now be found in their original location.
If the files aren't located in the recycle bin, they may be preserved if the hard drive is regularly backed up. Navigate to the software that is being used to backup the files, either to an external drive or the cloud, and follow the instructions to recover files from the last backup. If the files still can't be located, try using file recovery software. There are numerous free downloads for file recovery software available online that may be able to recover files that have been deleted from the recycle bin.
