I kindly ask for some knowledge about folder symbols some experts here might have; I'm going to trial some tools and am very willing to share my experience with them afterwards, it's just I don't have any knowledge on this subject yet, so I hope to better adjust my approach with some additional info.
There are some tools; one free tool just has got the same (closed) folder symbol we all know, in just a few (ugly) colors; I would need many more, and especially, many more (and brighter) colors for that same symbol. It seems there are many symbol collections out there, both free and paid, so the question here would be, in what format such symbol should / would have to be imported into the tool, in order to be as tiny and without problems as possible.
Then, there is a paid tool in two versions, where the free (or cheaper) one just replaces your folder symbols on your current system, but not for any use, for example by usb stick, on another pc (where the symbols of the folders in question you might have re-colored before, would then revert to the original yellow).
Of course, this intrigues me, not because I want just buy the cheaper version but have the functionality of the more expensive one, but because I would like to understand what's going on.
Of course, I know I can replace folder symbols by delving into the right-click menu, without buying any tool for this, but here again, the question arises if such a replacement will only work on the current pc, in light of what can be concluded by the different versions of the above-mentioned tool.
Why such replacements (other symbol and/or just other color) would not be persistent to begin with? What does Windows do with such symbols, meaning does it process them in any way, instead of just displaying them?
Of course, we have the problem here with two concurrent folder symbols, closed and open; I don't assume I would be able to use them both, I just would be happy to have the "closed" symbol, but in as many different colors as I need them.
And if Windows does indeed some processing of such folder symbols, the question arises if this processing is different between my XP, Vista, 7 and now 8.
And finally, it would be of interest to know if such new symbols work invariably in any file commander or if, depending on the file manager in question, you should be up for bad surprises, again, in case, because of some special processing the layman would not expect to be done behind the scenes.
That's why I greatly would appreciate some more info, also perhaps by links I didn't find (yet) on my own.
