The amount of time taken by the application to recover data depends on the following factors:
1. Type of scanning process
2. Size of the hard disk from which the data has to be recovered
3. Amount of data to recover
As the factors mentioned above are beyond the control of the application, speed of recovery process cannot be enhanced. However, you can reduce the time taken by the process by stopping the scanning process once desired files/folders are listed.
In the list of recently deleted files/folders in the tree window, select the desired files/folders and recover them.
Note: Advanced users can quickly scan and recover data by selecting specific region (starting sector and ending sector) using the Select Region slider in Raw Recovery option.
