I found it to be incredibly useful in helping me resolve some performance testing issues when experimenting with DLL loading alternatives. Pointed me to exactly the tool that I needed to avoid having my tests skewed by file system caching. I could only see it because I have enough privileges. I think it would be helpful to other programmers doing performance testing and should be available in the foremost forum for programmer questions.
This post wasn't actually closed, although it does cover the same ground as the pointed duplicate.
It opens with this:
What tools are available to either completely clear, or selectively remove cached information about file and directory contents?
While tools that programmers commonly use are on topic for Stack Overflow, this does delve a bit into the realm of pin a tool on my problem. It's anchored in a concrete problem that someone needed to solve, but as it's written, it invites a bit of a popularity contest when it comes to answers. I agree that the question should be closed, and I understand why the moderator responding to the flag deleted it, but clearly, there's content that might be worth salvaging here - perhaps through a merge.
To be clear, I'm not overriding the decision that the moderator took, it's clear to me that the action was taken because the question was quite old and very unlikely to gather votes in either direction from the community, and it is problematic. I don't think eyes on that question are a problem any longer - and I have restored the question, but in a closed state.
Have at it, if you think a merge is warranted - use your flags. If you think there's value in some answers that could be duplicated purely for the purposes of preservation - grab them, just be sure to give proper attribution.
