Perfect All File Locker - Pro Version

As its name implies, Perfect All File Locker is a piece of software that allows you to protect a file on your computer by assigning a password to it.

This is a portable app, so installing Perfect All File Locker is not necessary. This means that you can store the tool on a removable device (like a USB flash drive), save it to any computer and directly run its executable file.

You can always carry the program with you when you're on the move. An added bonus is that the Windows Registry does not receive new entries and no leftover files can be found after program removal.

The interface of Perfect All File Locker is based on a standard window where you can select a file for locking by using either the file browser or 'drag and drop' method. Unfortunately, you cannot import multiple items to encrypt (with the same password or different ones).

The application gives you the possibility of locking the respective file by key file (i.e. depending on another file) or by password. Hints can be added as well.

When you encrypt an item by using a key file, what Perfect All File Locker actually does is to calculate the MD5 checksum value of the key file and apply it as a regular password. In other words, it's not mandatory to store the key file for the encryption procedure, as long as you know its MD5 signature.

By default, Perfect All File Locker offers to delete the original files when the encryption job is done. This action can be disabled from the 'Option' tab or modified into making the app automatically delete or spare the original item after locking. You can select the encryption method; Perfect All File Locker can either lock the original file or create a new one.

The straightforward application requires a low amount of system resources to finish a task in reasonable time. It includes a help file but it's only in Vietnamese. Once a file is encrypted, the user can access its content without the help of Perfect All File Locker. For example, you can send it to other people via email, so they can open it by using the password you provide, and without the need for Perfect All File Locker.

On the downside, you cannot specify the output directory for the locked file (Perfect All File Locker automatically stores the new items in the same directory as the original ones). Moreover, the app does not integrate the option to remove the encryption from a file. Thanks to its intuitive layout, Perfect All File Locker can be seamlessly handled, even by inexperienced users.
