CD-DVD Lock - Version 2.31 CD-DVD Lock is intended for restricting read or write access to removable media devices such as CD, DVD, floppy and flash, as well as for restricting access to certain partitions of hard disk drives. You can restrict access by two ways: hide your devices from viewing or lock access to them. You can gain access to your devices back by entering a valid password that only you know. Your data on your media are not going to be encrypted or altered in any way, therefore if you forget your password, you'll never lose your data stored on the protected media. Moreover, it works more faster than any other software using cryptooperation mechanisms. The main purpose of the program is to restrict an ability of copying data between removable media and hard disk drives as well as deny access to media itself. CD-DVD Lock will allow you avoid many of headaches connected with unauthorized software installations from any removable media, and also prevent data leak by removable media.
