The main function of HiLog is keylogging, i.e. keyboard input capture.
This software allows you to intercept user keyboard input and user clipboard data.
You can customize the results of the keyboard capture telling program to add time of the capture and/or name of the window in which capture had happened.
Clipboard data captured by this software could be two types - text and file lists (in case of file copying or moving).
Also, you can specify file size of the file that will contain captured text data, depending on predicted amount of captured keyboard input (10000 - is a good size if you don't know what do you need).
