It’s crucial to remember that the likelihood of successful data recovery depends on a number of variables, including the state of the storage medium, the period since the files were deleted, and the amount of activity on the drive in the wake of the deletion. As a result, there is no assurance that Recuva will always be able to properly recover your files.
To prevent overwriting any possibly recoverable data, it is always advised to install and execute Recuva on a different drive from the one from which you want to recover files.
