Advantages and disadvantages

According to numerous ratings from ordinary users and professional magazines, this program has been the leader among utilities for recovering deleted files for several years now. However, like any program, it has its advantages and disadvantages.

The advantages of the product include:

• Russified, intuitive interface;
• availability of a fully functioning free version;
• interaction with any types of information storage devices - from hard drives to memory cards;
• the ability to manually select places to search for lost files;
• search for system and hidden files;
• the ability to restore the structure of previously erased folders and archives;
• work with most of the most common formats, types and types of information: text documents, tables, presentations, photographic materials, audio and video files, folders, archives, etc.;

The disadvantages of the product include:

• duration of work - from several hours even with a simplified search;
• the ability to restore only those files whose condition was rated as excellent after data search - if their quality is average or worse, then they cannot be restored.

In practice, the vast majority of files do not lose their quality when deleted

The program can recover different types of files, but only if they are erased in a standard way, when moving and then emptying the Recycle Bin or formatting the disk. If you previously used any other utility to permanently delete files, then Recuva will not be able to restore them.

How to use the program - features and functions

Recuva is a utility that every technology user will need at least once, since no one is immune from accidental file deletion or system failures. How to work with this program?

Installation

Interface and Features Overview

After launch, the program will automatically prompt you to select the type of files that need to be recovered. To improve the quality of your search, it is recommended to check the in-depth analysis box.

How better program will analyze the disk, the more deleted files it will find

Upon completion of the search, the program will display a list of files that have been erased but can still be restored. The color of the circles next to the file name indicates the likelihood of success. Green ones have the maximum chances, red ones have the minimum ones.

Most files, as a rule, are completely recoverable

You need to check the boxes for the files that you want to return from “oblivion” and click the corresponding button in the lower right corner.

On the right side of the screen, to make selection easier, there is a “Summary” tab, which contains detailed information about erased files.

In many cases, it makes sense to listen to program recommendations

Please note that regardless of the type of drive from which data will be recovered, the procedure for using the program is the same.

What media does it work with?

Possible problems

“Partially recovered” files cannot be opened in the future

The second common problem is that the program may not “see” the connected equipment: flash drive, phone, video camera, etc. First, it is recommended to disconnect the device from the computer and try to connect it again. If this does not help, you should update the device drivers. To do this, go to the “My Computer” tab, select the device, right-click on it and select “Properties”.

The inability to recover after secondary deletion is the only problem that cannot be solved. If files were erased from the drive and after that new information was written to it or some other files were deleted a second time, then the utility will not be able to restore the originally erased ones - it simply will not find them.
