There are several ways to recover deleted pictures from a folder, depending on the situation.
Firstly, if you have a backup of your files, then you can easily restore your deleted pictures from your backup. This is a straightforward solution as long as you have regularly backed up your files.
Secondly, if you have not taken a backup of your files, then you can try using a file recovery software. There are multiple free and paid file recovery software available for download online that can help you recover deleted pictures. You can download and install a reputable file recovery software and then scan your computer system for deleted pictures. After the scan, the software will display a list of deleted files, from which you can select the pictures you want to recover.
It’s essential to minimize any further writing of data on your hard drive after you have deleted files as it can cause permanent data loss, even if you try to recover the files with a file recovery software. Therefore, it's recommended to stop using your computer or the specific drive where the deleted files were present immediately after you realize your pictures are missing.
In conclusion, if you have a backup of your files, restoring your deleted pictures is typically an easy process. If you don’t have a backup, using a file recovery software can help to recover lost files, but it's not always guaranteed. Therefore, prevention is still better than cure – always take backups of your data and essential files to avoid unnecessary data loss.
