When you delete a file on a computer, it is never truly deleted or erased as the content of that file is still intact. For example, considering how to restore deleted files, on Windows you will find them in the Recycle Bin and on Mac they will be moved to trash. Then all you need to do is press restore and the file will return to the original location.
However, many people press shift-delete or use other methods to permanently get rid of files or to make them skip the recycle bin step. However, even though you have that specific file space open to store other files, the original file still has not been permanently deleted as the space is not used immediately. If you want to recover a file, it is thus vital that you do it as soon as possible and, depending on the capacity of hard drive you might not have a lot of time before the space is re-used.
If you have defragmented your hard drive after deleting a file, your chances of recovering a deleted file is quite slim since the computer has officially opened up free space. This is where recovery software comes into play. You can easily acquire tools or undelete software to help, but these are not usually included in normal operating systems.
These tools do not guarantee recovery of deleted files, but the software comprehends the systems used to delete these files and can help you locate the missing files. Most files can be found, but it does not mean that these files have not been altered. Depending on how often you change files or create new ones, these undelete programs can often recover files from months and years ago.
If you have a Windows operating system, the apparent top program for recovering deleted files is the “Uneraser”. This system makes extensive use of complicated recovery algorithms and creates thumbnails for you to identify lost files as quickly as possible. This makes it possible for you to see deleted files immediately instead of searching through other deleted files.
However, when choosing a program to restore deleted files, always try out a trial version first to see if you understand and trust the product. Whether on Windows or Mac, you should be able to make sense of what the program does. Make sure the program recovers the file as it was and not fragmented files.
When it comes to Apple Mac, a great program is Data Rescue 3, which is used by professional recovery services. It recognises over a 100 popular file types and constantly upgrades algorithms to give customers a top file recovery service. What makes the program unique is its bootable DVD image which can recover lost files from a computer that cannot start up.
What you can also do, with regards to how to restore deleted files, is connect a Mac disk drive to a Windows computer and use a program like the Uneraser to recover data. This method does not guarantee success, as does other recovery processes, but it could be used in some extreme cases. Ultimately, it can also be a good idea for you to take your hard drive to the nearest computer service shop and they can either recommend a program or use recovery methods themselves.
