Files that has been replaced, even just once, is generally considered to be unrecoverable. There have been theories regarding the feasibility of recovering replaced data, but none have been put into actual practice. As such there is no evidence in favor to recover replaced files, but several suggesting it is entirely impossible.
Overwriting is a process of writing a binary set of data in computer data storage and is a term used to describe when new information replaces old information or data. In general it writes over the previous data, hence the name. Overwriting generally occurs when unused file system clusters are written upon with new data, though overwriting is also used in security algorithms. These algorithms use a precise set of rules to remove any part of an original data from the memory by writing a new raw data on the memory.
Sometimes the file (such as excel, word document) is not saved in the case of being covered or replaced, and want to restore the file is extremely high degree of difficulty; sometimes the folder structure is damaged or covered, but the file content is not Lost
Sometimes the file is automatically saved, and the newly overwritten file does not really cover the actual old file in the disk storage area.
In short, when the file or folder overwrite or replace, do not be nervous, do not continue to write to the disk.
There are a lot of data recovery software can be used to recover replaced files or folder.
But, keep a clear mind, because the complexity of data loss, and different software algorithm strategy is different, no software can 100% sure to recover of any data lost in any case.
On the other hand, all kinds of software has its own unique function, can solve the unique problem;
This is the meaning of their existence.
You need to do is to remain patient, choose more try;
Aid file recovery software also has a lot of complex strategies, can try to solve many complex causes of data loss problems, of course, is not 100%;
What you need to know is that we have “undelete” “unformat” “recover partition” “full scan” “android recovery” and other ways to try to solve your problem;
In most cases, it is possible to restore the file system and partition structure, as well as the file directory structure and various files, and to recover many files according to the file format in difficult cases.
