I noticed that when you commit or checkout files using Git in a Windows environment, the file attributes are not preserved (for example hidden or read-only). If I commit a hidden file and then I check it out on another computer, the file is no more hidden. Is it possible to make Git recognize Windows file attributes?
No. Git doesn't track full UNIX permissions either, it just remembers the executable bit for convenience. As to why — it's a version control system, designed to track primarily source code. Which makes that feature downright useless (not to mention 'hidden' attribute is quite useless on its own, too).
