Where did all the space go on my hard drive? I have a 74.4 SSD drive.  Disk Properties tell me that it has around 2 GB left.      However, if you add up all the files &amp; folders, only ~ 60 GB is taken up.  Where are the other 14 GB?
Almost half of disk space unaccounted for on Windows 7 computer I'm trying to determine what's eating almost half of disk on my Windows 7 Lenovo laptop but haven't been able to determine what.  I read some of the answers on this site but none of the causes seems to be the cause of my problem.  What I've done so far:   Checked Windows' System Restore points but only minimum use, either way I deleted around 2GB if usage from there Used WinDirStat and it came back with a total of 71.3GB usage at the root level C Drives properties says 135GB being used out of 138 GB total, ie, 135 GB - 71.3GB = 63.7GB missing somewhere No "Unknown" files reported by WinDirStat Windows Disk Management utility doesn't report any unused partitions or unclaimed space chkdsk comes out clean Windows disk cleanup tool doesn't report anything big, just small stuff in the lower MB range Lenovo backup tool hasn't been used nor there is a folder for the backup images   Any idea on what to look at and/or do?  EDIT: some additional info...
Comparing currency values as floats does not work In the movie Wonder Woman, we see Wonder Woman as a child who grows into an adult. During the same time we see the people around her - the Amazons - not seem to age at all. It's revealed that Wonder Woman is special.      She's actually a God and presumably immortal   The Amazons are, well, not quite human, but they aren't the same as WW.   It's also revealed that:      A long time ago there was a war between the Gods and all of them perished by the hands of Ares. Before Zeus died, he created Wonder Woman out of clay.   All of the Amazons have bronze aged weaponry and do not seem aware of the changes to the outside world. This suggests that they are several thousand years old.   Presumably Wonder Woman has a normal life span as a child and has just become an adult at the beginning of the film. This seems very incongruent to me. Maybe I missed something though.  So, does the film or the DC Extended Universe give any indication of how old Wonder Woman is? Or is my assumption that she's several thousand years old (based on the weaponry) correct, despite the apparent incongruity I brought up? How tall is Supreme Leader Snoke? In Star Wars: The Force Awakens, we see Supreme Leader Snoke a few times dispensing orders to his subordinates.      However, we always see him communicating via hologram, and we've seen in previous Star Wars films that these holograms are often projected at a different size than the original person is.   So how tall is he really?  I don't think we ever got a good shot of him with something to give a sense of scale. Evaluate the following limit of finite sum Is temperature a Lorentz invariant in relativity? Cursor hitting "border" between differently sized monitors I'm not sure if I'll be to explain this right. I have a dual monitor display on Windows 7 and my left monitor (laptop) has a lower vertical resolution than the right monitor (regular LCD monitor). So obviously, if I stick these monitors together, there's a part in the upper-left corner of my LCD monitor where cursor cannot go to the other monitor. I remember there was a trick to make this gap disappear, and make it seem like the monitors are of equal height.  Any suggestions?  By the way, I am also using UltraMon. Why didn’t anyone dial Abydos before Daniel solved the mystery of the seventh symbol? From what I recall from the movie, Daniel only finds the seventh symbol... however when he explain they give way to show him the star gate and they put their sequence in the dialing computer. This proves the dialing computer was prepared to dial 7 chevrons.  It’s also stated they’ve also tested the 6 previous symbols in the order they appear on before, one has to assume only to fail when they insert the 7th, making them aware of the fact you can, at least dial 7th chevrons.  With 39 chevrons on the gate and 6 already locked in, that leaves 33 to try to get a lock. Those are not that many not to go and simply try one by one so... how come nobody brute forced the thing? How to prove and interpret $\operatorname{rank}(AB) \leq \operatorname{min}(\operatorname{rank}(A), \operatorname{rank}(B))$? Bag-of-Words for Text Classification: Why not just use word frequencies instead of TFIDF? A common approach to text classification is to train a classifier off of a 'bag-of-words'. The user takes the text to be classified and counts the frequencies of the words in each object, followed by some sort of trimming to keep the resulting matrix of a manageable size.  Often, I see users construct their feature vector using TFIDF.  In other words, the text frequencies noted above are down-weighted by the frequency of the words in corpus.  I see why TFIDF would be useful for selecting the 'most distinguishing' words of a given document for, say, display to a human analyst.  But in the case of text categorization using standard supervised ML techniques, why bother downweighting by the frequency of documents in the corpus?  Will not the learner itself decide the importance to assign to each word/combination of words?  I'd be grateful for your thoughts on what value the IDF adds, if any. Any Set with Associativity, Left Identity, Left Inverse is a Group Why are my villagers attempting to breed (they have the red hearts) but then stop breeding suddenly and gray "angry" particles pop up? I set up a villager breeder and set down 4 beds with 2 villagers in the middle and a carrot farmer supplying them with carrots. The first time both of those villagers bred the breeder worked perfectly fine. After that, however, the gray angry particles popped up every time they would try to breed (they would engage in breeding at a normal pace, just could not actually produce a baby). I even killed the one villager they produced in case it took a bed and even then, the two villagers would not breed anymore. Is there something I have done wrong? This seems odd considering they were only able to breed once and even by eliminating their offspring the villagers could not breed again. Edit: version is 1.16.4 View linked Excel 'Windows' on separate screens I have a layer of georeferenced points, and a layer of vectorized borders. Is there a way I can use QGIS to calculate how many points fall within each area of the borders layer? Rootspaces are $\mathop{ad}$ nilpotent Is an idle temperature of 66°C for the A10-6800K CPU normal? I have an A10-6800K CPU and Piriform Speccy says that my CPU temp is 66 celcius in idle, the same goes for HWMonitor.  Is this normal/ideal? I have a  with a . packed vs unpacked vectors in system verilog Looking at some code I'm maintaining in System Verilog I see some signals that are defined like this:  node [range_hi:range_lo]x;   and others that are defined like this:  node y[range_hi:range_lo];   I understand that x is defined as packed, while y is defined as unpacked.  However, I have no idea what that means.  What is the difference between packed and unpacked vectors in System Verilog?  Edit: Responding to @Empi's answer, why should a hardware designer who's writing in SV care about the internal representation of the array?  Are there any times when I shouldn't or can't use packed signals? How would one throw an unwilling creature? My bugbear barbarian, who can lift about double the weight of a wolf, wanted to throw the wolf at a second wolf. How would we go about doing that given existing rules options?
