Windows Tips: Hide Your Files

This computer tips are talking about hiding your files.

The files that we are talking about are *.rar or *.zip files and they will be combined with *.jpg files, so the original file (*.doc, *.xls, *.ppt, & anything others) "will be considered" as an image file (*.jpg, *.bmp, *.png, & something like that).

These protection tips aren't Linux tips but absolutely Windows tips.
The most fundamental thing is that you make sure the file you'll be hidden was been archived into a *.rar or *.zip format. After all files converted into *.rar or *.zip format, then you can insert it into the image file to be hidden. Follow the instructions bellow:
1. Prepare *.rar or *.zip file that will be hidden. E.g. myfile.rar
2. Prepare an image file. E.g. pict1.jpg
3. Save all files (myfile.rar and pict1.jpg) into one drive and directory. E.g. D:\
4. Open command prompt, and go to drive D. E.g. D: (press enter)
5. Type this command (without quotes) and press enter:
"copy /b pict1.jpg+myfile.rar result.jpg" (it will create a new file, result.jpg).
result.jpg is a file which contains myfile.rar and pict1.jpg but appears as a standard image file.
6. To open the result file (result.jpg) just right click ==> Open with ==> and select winrar or winzip (hidden files visible!!!).

Note: make sure all files you named have no space (E.g. my file.rar <== incorrect name). The security tips above are great to gives you minimal protection from the hands of people who want to know your personal files. Good luck!!!

    network.http.max-connections = 64
    network.http.max-connections-per-server = 20
