'needs-no-dep-files'
In finder I have a file with 3 items called "s-needs-no-depfiles". I haven't created this file. It's a Macbook Pro version c 2009. OS Mavericks. I have performance issues with the machine, and question marks over security, would like to understand the relevance of the file to any of this.
MacBook Pro, OS X Mavericks (10.9.5)
