What to do to restore deleted files isn't actually all that difficult, whether the files have been deleted from a PC or a Mac. There usually comes a time in any computer users life when a file has accidentally been deleted and sent to a trash bin and then the bin has been emptied. It goes without saying, of course, that the file in question was actually very important.
Fortunately for most computer users, there are a number of ways in which one can find a file and then restore it back to a folder or directory. In fact, there is almost nothing that ever deleted from a computer hard drive that is actually gone forever. The hard drive will move the deleted file out of the way and mark it, and it will eventually be overwritten, which can make it harder to recover, though it won't be impossible.
What you should understand first of all is that you have a better chance of being able to restore deleted files when you can make use of any one of a number of quality undelete or file recovery programs available on the market. With them, it's only a matter of a few clicks of a computer mouse to get the program back. Without them, it's more difficult, especially if the file has been overwritten a number of times.
Once you realize that you've accidentally deleted a file, it's very important that you stop using the computer right away. This is because the file that's been deleted will be overwritten at some point, which decreases the chance of recovery. Windows certainly has a number of file recovery software programs out there that can greatly aid in the restoration effort, though.
Mac computers also are easy enough to go through and then find and restore deleted files, though many of the better software programs cost a bit of money. After you have the program and have uploaded it, open it and then directed to scan the appropriate drive. After a time, you'll be given a list of files, photos etc. That you'll have to sort through in order to begin the search.
Go through the list -- and there will be a number of files that are nothing more than small bits that the computer created to help it run itself -- and search for the file in question. Once you've identified it, it's only a matter of right-clicking on the file and then sending it back to where ever it is you need it to reside. Remember, stop computing operations until you can find and then restore deleted files.
