Again i really don't know what you are actually telling us there but i suspect it's maybe something important of which i at least am not aware. The majority of users here use a PC to access their units and media cards to add, delete or modify files and folders. Those who use a Mac and have trouble usually then don't when it is suggested to them to use a PC, which is the standard advice from PC users. But at least then if they do continue to have problems it is simpler to help them because then we can better work out what happened and advise them accordingly. I don't want to turn this discussion into a Mac v. PC thing (i know next to nothing about Mac anyway and am far from a PC expert as well), but i have never seen or heard a comment similar to yours:

My lack of understanding could be partly due to the wording of it (google/bing translation to English, maybe from Russian?) and perhaps you are saying something like this:

Hiding Garmin files in Windows is dangerous. (if so, why?). I think that you should use the appropriate software. (what software do we need to use then?). Windows causes damage (or interferes with/alters/modifies files) which could cause a malfunction of the Garmin unit. (how does Windows do that to them and to which specific files/folders, and what particular malfunction/s result?).
