There are times when the most crucial software programs are unreliable and will crash, causing crucial files to be lost. But there’s still hope. The files are often still available on the computer in some form ready to be recovered by recovery software.
But computer users only have a limited amount of time before the data is lost forever. Files essentially remain until the computer decides to allocate the space that was formerly allocated to the computer. When this happens, the data is lost forever. The longer that users wait to utilize recovery software, the more likely that the files will be lost forever. Backup software or recovery software is necessary when the computer system has not backed up all of the files and a mishap leads to important files being deleted. This mishap could be human error, a problem with a software program or a hardware malfunction. If the files are important enough, the user might wish to recover the files with recovery software. Recovery software often has a scanning feature where users can search for specific files that they have lost. However, this feature requires that the user remember the file name. Recovery software also often has a full scan that allows users to scan the entire computer for files. This process takes much longer, but is helpful when a large number of files are lost for a variety of reasons. To cut back on time, some types of recovery software have features that allow users to scan specific areas for lost files. This is especially helpful when the user knows where the file originally was, such as when the user recently deleted the file.
Some users can recover files without any software if they have certain operating systems, such as Windows 7. Windows 7 has a feature called Volume Shadow Service, which keeps a copy of a file for up to one day. Regardless of how the file is recovered, it must be recovered quickly or it may be written over, meaning that it is lost forever.
