If you are the type of person who usually works with lots of sensitive electronic documents, you will probably put passwords on some or all of them to ensure no one else has access to them.

But what happens if you actually forget one? These files aren't like your typical online account where you can have a link sent to your e-mail address so you can reset the password. If it happens, then you can seek help from PDF Password Recovery.

The program is pretty straightforward and easy to learn. You just need to select the file for which the password should be recovered and choose the recovery method, and then the program will take care of the rest.

While the process is running, you can have the program shut down your PC after it is done. If you choose this, the recovered password will be saved in a text file in the installation directory, and you will be able to see it when you switch the computer back on.

The program can recover a password in three ways. One of them is by brute-force, which basically tries every possible character combination until it finds the right one. It is a sure-fire way but also lasts the longest.

Another one is the mask mode, where you can select which characters the program should choose in its combination attempts or specify how it began or ended. It is very helpful when you remember parts of the password, so the process can be done faster.

The last mode the dictionary method, where you can use an inbuilt or personalized one to search only through its words. This is practical in cases where you have a few passwords that you use over and over but are not sure which one you picked for the file in question.

This isn't a must-have application that everyone should have pre-installed. But in case you find yourself in a situation where you cannot remember a password for an important PDF file, then you can safely rely on PDF Password Recovery.
