Nowadays, many people have learned that after the computer hard disk files are deleted, the deleted files can be recovered through the data repair tool, but this does not mean that they are omnipotent. There are two types of files that are difficult to recover after deletion.

1. It is difficult to restore compressed files after deletion.

Many friends like to organize files and use compression tools to package and compress many files, which saves space and is easy to manage. However, the compressed file has a drawback: once the compressed file is lost, even if only 1% of the data cannot be found when the data is recovered, the entire compressed file cannot be recovered and the contents cannot be read at all.

In addition, not all files will be significantly reduced after compression, such as MP3, JPG images and other files themselves have been compressed, even if compressed again, the volume will not change significantly. Therefore, the compression of such files may not only lead to loss and can not be recovered, but also get half the result with twice the effort.

2. The success rate of "big guy" file recovery is low.

Larger files occupy more space on the hard disk and are more likely to be overwritten after deletion, so the success rate of recovery is also reduced accordingly. Experts suggest that larger picture files, video files, disk image files (such as Ghost files) should be properly saved, once mistakenly deleted, and finally immediately shut down, find professional assistance to restore.

Notes after file deletion

First of all, stop the read and write operation of the computer, and the data is saved on the hard disk, just like putting things in a small room in the warehouse. After the user deletes the data, only the "room" address is marked with "delete", and the data is not cleaned. Only after the new data is saved to these "rooms" will the previous data be overwritten. Tools such as North Asia data recovery software WINDOWS Professional Edition V1.0 are based on this principle to retrieve mistakenly deleted data before the new data is overwritten.

Therefore, my emphasis on the principle of "stop all data reading and writing operations immediately after data loss" is easy to understand.

Secondly, for particularly important data loss, if the user is not familiar with the computer, it is recommended to go to a recovery company like Beijing North Asia data recovery Center for manual recovery; if you have a basic understanding of the computer, you can download and install our North Asia data recovery software WINDOWS Professional version v1.0 software.
