Stop and identify where the files were stored
Close applications that are writing to the affected drive and pause new downloads there. If the missing data was on a removable device, disconnect it until you have a recovery plan. Note the original location and whether the event was deletion, formatting or a device failure. These situations are different, and more software is not always the right next step.
Check the Recycle Bin, backups and any cloud version history first. Restore from a known good copy when one exists. A file merely moved to another folder does not need deleted-file recovery. Avoid running cleaners or formatting a drive because Windows suggests it; those actions can change the data you are trying to preserve.
Decide whether an ordinary scan is appropriate
A readable drive with a recent accidental deletion is a more suitable candidate for Recuva than a device that clicks, repeatedly disconnects or cannot stay accessible. Stop ordinary attempts on hardware showing physical symptoms, especially when the data is irreplaceable. CrystalDiskInfo can display available health information from a responding drive, but cannot repair damage or certify that continued use is harmless.
Keep in mind that SSD TRIM and internal cleanup may remove deleted data even after a short time. Overwriting can make recovery impossible on other media too. Neither a deep scan nor a paid license guarantees that those contents remain. For highly valuable data, consider specialist recovery before creating additional activity.
Prepare Recuva away from the source
Download and install Recuva on a separate healthy drive. If the loss occurred on the Windows system disk, installing there can itself overwrite deleted data; arrange an appropriate alternative system instead of automatically proceeding. For a stable external source, attach it when the tool and destination are ready.
Choose the relevant file type and original location in the wizard, then run the ordinary scan. Try a deeper search only if necessary and if the device remains stable. Inspect names, available previews and condition indicators. Favorable indicators are not proof that the recovered document will be complete.
Recover to another physical device and verify
Select important files first and save them to a different physical storage device. Another partition of the source is not the same protection. Writing results onto the affected disk can overwrite additional recoverable content.
Open copies of the recovered files and check their actual contents, not just their names and sizes. Keep the source unchanged until you have confirmed what was saved. Once the useful data is secured, establish another backup so that the next deletion can be resolved from a copy rather than another uncertain scan.
A missing partition calls for a different approach from one deleted document. TestDisk can examine partition structures, but writing changes requires understanding the layout and having a backup. PhotoRec searches for recognizable file contents when filesystem metadata is unavailable; original names and folder organization may be lost. Save recovered output to another device and avoid writing repairs to the only copy of valuable data.
