Double Files with a space at the beginning

Why did this happen and how?



The reason they are double is it happened after synchronization, but what the hell!
I never came across with this before.

If you have taken ownership (or used the "take ownership" hack) on any of your system and/or hidden folders, this can be a primary reason??

These are not hidden files, they are in the music library.
Why would the system consider them hidden or system files?
And is there a fix so it wouldn't happen again?
The term "sharing" should mean "easier to share" not "harder to use even if the files are in your computer". I hope there will be a solution for "sharing" in the near future.

Not exactly what I said. But I am just offering a reason., as I have had the same experience by taking ownership of junction files.

Thanks for your replies.
My surprise was why there was a space at the beginning since these are mp3 files in music library in a disk (whole disk is one partition) dedicated to libraries.
This was my first time having this kind of error.
I am always having trouble with security and sharing because I have more than one machine with several operating systems.
The worst thing with me is, I don't want to share any of these files with homegroup (I am connected a homegroup where I don't them to read my files, but I need to be in the homegroup to read/write their files).
