i-Lock

i-Lock is a simple-to-use program designed to help you protect files on your USB flash drive. It can be easily handled, even by first-time users.
This is a portable app, so i-Lock does not come with an installation package. It is only necessary to save it to the USB flash drive, in order to directly run its executable file.
Therefore, the Windows Registry is not updated with new entries and no leftover files can be found on the hard drive after program removal.
Upon initialization, you can required to specify a username, password and encryption key. If you want, you can also fill in a field with a message, in case the USB drive gets lost and you want it returned.
The interface of the app is based on an Explorer-based layout that helps you locate and copy items to the removable device. There are two copying methods available - normal and by encrypting a file with a password.
Therefore, in order to access its contents, the users must type in the username and password. Moreover, you can encrypt the existing files on the storage device, based on the settings you have configured.
The straightforward utility does not put a strain on the computer's resources, as it barely uses CPU and system memory. It has a good response time and worked smoothly during our tests; no error dialogs have popped up and i-Lock did not freeze or crash. What sets this tool apart from similar software is that it allows you to protect only specific files of the USB drive, not necessarily all of them.
All in all, i-Lock provides a simple yet efficient solution for securing a USB flash drive. Thanks to its intuitive layout and overall simplicity, first-time users may seamlessly discover how to work with its features.
