    The finder indicates available capacity is 140,53GB. Disk Utility shows only 123,84 GB, in the rMBP in my signature. Almost 17GB difference!!!:confused:

    I had read earlier somewhere, that there will always be some difference between these two readings (and the one in Disc Utility is the one that should be trusted...) but is this much normal in a 256GB Flash Storage Drive with Yosemite?

    Is there any safe and free way that I may get rid of any junk files, which should be there in some amount?

    Thanks for any assistance.

    Download and use OmniDiskSweeper. It will provide a sorted list of what's consuming your space.

    If you run it with sudo (As shown below), it will include some system files that it woud not normally have access to scan. That is a more accurate representation of what's consuming your drive.
    Code:
    sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
    Another option is to use this terminal command
    sudo du -d 1 -x -c -g /

    I prefer to redirect it to a text file (this puts it in your Documents folder
    sudo du -d 1 -x -c -g / > ~/Documents/du.txt

    Like the sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper command, it will scan all directories, but produce a text file as opposed to showing the results in a window

    I see you have a Time Capsule, so assume you have Time Machine turned on. It is Time Machine's local snapshots likely using that space and it is normal.

    From the help doc:
