How to make invisible folders or files

I have come accross a neat tricks, this is applicable in windows OS, I haven't try it in macintosh though.

First you create a folder, it will come out with a blank folder and the name should be "new folder". rename the folder by blocking all the letters and you press ALT+0160 (ascii code) it will show a blank symbol. Right click the folder and you click customize, change icon, there will be a couple of icons showing. find an icon that is blank icon, in my computer there is 3 blank icon in the row, chose either of one and apply it.
refresh your folder and you are done, the folder is invisible, if you want to hide some stuff from anybody this is a good trick though.
happy trying!!

 

please give your comment about this tricks, I would like to know how you guys rate it

 

well I found some weakness in this method though, and I am not sure it will affect back up of utilities, because I have tried some of utilities that related with icon stuff, seems the blank icon it is an icon afterall, however if you put this invisible folder in a folder, to find out this folder all you need to do is just change the view of the folder to "view by list" eventually it will show some some gap in the list
