If the installed system deletes the files on the c-disk by mistake, you have to use the recovery software.
The recovery rate after data loss is different in different cases.
When the files in the computer are deleted intentionally or unintentionally, or damaged by a virus, or the partition is formatted, if you want to recover these lost files, you can use this function. In fact, when the operating system deletes a file, it only marks the deleted file as "deleted" and marks the disk space occupied by the file data as "free". The file data has not been erased, but still quietly "lying" on the disk. As long as no new files are created after deleting a file, and the operating system does not write new data, the deleted file data will not be destroyed, and there is a chance that they can be "rescued" through certain technical means.
Formatting does not take into account the contents of the original data on the disk, nor does it delete the old files first. The specifics of formatting vary by file system type. For file systems such as FAT32, FAT16, FAT12, etc., formatting clears the file allocation table (or FAT for short, which is fixed at the beginning of the partition and contains information about the location of file data) and the root directory. File data is generally not erased. For NTFS file systems, there is no fixed location requirement for newly written data during formatting, but under normal circumstances the write location does not change with each formatting. Therefore, most of the old file data will not be overwritten, and there is still a lot of residual information for us to find the lost files.
FAT or FAT32 partition, deleted or formatted, larger files or frequently edited and modified files, the recovery success rate is lower, such as frequently edited and modified XLS or CDR files is very difficult to complete recovery. Those files copied into the file will not move, the recovery success rate is higher, such as PDF or JPG, MPG and other infrequently modified files, the recovery rate is still relatively high. This is because FAT and FAT32 partitions use the file allocation table to record the cluster chain fragmentation information for each file, deleted or formatted after the cluster chain fragmentation information is cleared, those who often edit and modify the file due to the dynamic growth of their file lengths in the file system are generally not continuous storage, so the file fragmentation information can not be recovered, the file recovery will not be complete.
The recovery probability of NTFS partitions is relatively high, and most of them can be recovered after deletion or formatting. Some files sometimes can not be recovered, for example, the length of the file is very large or the file is edited and used for a long time, this file will form a lot of fragmentation information, after deleting the file, this file can not know the length of the file, and it is difficult to recover, for example, some of the use of many years of database files, after deletion, with the data recovery software scanned the length of the file is 0, and can not be recovered. Regularly doing disk defragmentation can reduce this situation, but directly doing disk defragmentation is also risky, please refer to the above need to pay attention to the problem.
Repartitioning or deleting partitions or partition table destruction, generally the back of the partition can basically be completely recovered, the more back of the partition is destroyed the lower the possibility, so the important data is best placed in the back of the partition, do not put in the C, D disk.
Files deleted from the Recycle Bin are sometimes not found, and under NTFS, files deleted from the Recycle Bin have their filenames automatically changed to De001.doc or something like that, and the original filenames are corrupted. When your data is lost and you can't find the file name directly, remember not to miss these files that have been renamed by the system. Shift+Del will not destroy the file name if you delete it directly.

In many cases, even files that have just been deleted cannot be retrieved by ordinary deletion recovery function. This is because the important information in the deleted file has been corrupted by the operating system or by user misuse. This kind of operation that leads to secondary destruction often happens inadvertently. For example, after deleting some photo files by mistake, you immediately open "Explorer" to look for the files you just deleted in various directories and use the thumbnail preview function of Windows. This is exactly the kind of action that is enough to destroy a lot of important information about the deleted files. This is because the thumbnail preview function creates a thumbnail cache file underneath the folder. There are many similar inadvertent actions. In this case, it is necessary to recover the files by means of "Scanning for file types". Although the files found in this way are named with serial numbers, you can still confirm them by previewing them or copying them and opening them. It is especially effective in recovering photos and Office documents.
