tl;dr: Windows' MAX_PATH is the devil, and it basically does not allow you to copy files with paths that exceed this length. No matter what. Even with official fixes and workarounds.
Long story:
So, I haven't had actual gainful employ in quite awhile. I've been earning just enough to get behind on bills and go without all but basic groceries. Because of this, our electronics have been ... in need of upgrading for quite awhile. In particular, we've needed new drives. (We've been down a server for two years now because its drive died!)
Anyway, I originally bought my external drive just for backup, but due to the above, I eventually began using it for everyday things. including Steam. over USB. Terrible, right? So, I decided to mount it as an internal drive to lower the read/write times. Finding SATA cables was difficult, the motherboard's SATA plugs are in a terrible spot, and my tiny case (and 2yo) made everything soo much worse. It was a miserable experience, but I finally got it installed.
However! It turns out the Seagate external drives use some custom drive header, or custom driver to access the drive, so Windows couldn't read the bare drive. ffs. So, I took it out again (joy) and put it back in the enclosure, and began copying the files off.
The drive I'm copying it to is smaller, so I enabled compression to allow storing a bit more of the data, and excluded a couple of directories so I could copy those elsewhere. I (barely) managed to fit everything with some pretty tight shuffling.
but. that external drive is connected via USB, remember? and for some reason, even over USB3, I was only getting ~20mb/s transfer rate, so the process took 20some hours! In the interim, I worked on some projects, watched netflix, etc., then locked my computer, and went to bed. (I also made sure to turn my monitors and keyboard light off so it wouldn't be enticing to my 2yo.) Cue dramatic music ~
Come morning, I go to check on the progress... and find that the computer is off! What the hell! I turn it on and check the logs... and found that it lost power around 9:16am. aslkjdfhaslkjashdasfjhasd. My 2yo had apparently been playing with the power strip and its enticing glowing red on/off switch. So. It didn't finish copying.

Anyway, finding the missing files was easy, but what about any that didn't finish? Filesizes don't match, so writing a script to check doesn't work. and using a visual utility like windirstat won't work either because of the excluded folders. Friggin' hell.
Also -- and rather the point of this rant:
It turns out that some of the files (70 in total, as I eventually found out) have paths exceeding Windows' MAX_PATH length (260 chars). So I couldn't copy those.
After some research, I learned that there's a Microsoft hotfix that patches this specific issue! for my specific version! woo! It's like. totally perfect. So, I installed that, restarted as per its wishes... tried again (via both drag and `copy`)... and Lo! It did not work.
After installing the hotfix. to fix this specific issue. on my specific os. the issue remained. gg Microsoft?
Further research.
I then learned (well, learned more about) the unicode path prefix `\\?\`, which bypasses Windows kernel's path parsing, and passes the path directly to ntfslib, thereby indirectly allowing ~32k path lengths. I tried this with the native `copy` command; no luck. I tried this with `robocopy` and cygwin's `cp`; they likewise failed. I tried it with cygwin's `rsync`, but it sees `\\?\` as denoting a remote path, and therefore fails.
However, `dir \\?\C:\` works just fine?
So, apparently, Microsoft's own workaround for long pathnames doesn't work with its own utilities. unless the paths are shorter than MAX_PATH? gg Microsoft.
At this point, I was sorely tempted to write my own copy utility that calls the internal Windows APIs that support unicode paths. but as I lack a C compiler, and haven't coded in C in like 15 years, I figured I'd try a few last desperate ideas first.
For the hell of it, I tried making an archive of the offending files with winRAR. Unsurprisingly, it failed to access the files.
... and for completeness's sake -- mostly to say I tried it -- I did the same with 7zip. I took one of the offending files and made a 7z archive of it in the destination folder -- and, much to my surprise, it worked perfectly! I could even extract the file! Hell, I could even work with paths >340 characters!
So... I'm going through all of the 70 missing files and copying them. with 7zip. because it's the only bloody thing that works. ffs
Third-party utilities work better than Microsoft's official fixes. gg.

On a related note, I totally feel like that person from http://xkcd.com/763 right now ;;21 -
Just in case nobody has mentioned this yet:
Yes Microsoft I do have a dualhead setup.
Yes Microsoft I do want to watch video on my left screen while having window focus on something on the right monitor.
No Microsoft this doesn't mean that I *lost* focus on the left window.
No Microsoft this doesn't mean that I want your Movies and TV application to suddenly minimize (and continue playing anyway) while I focus on some server monitoring window on my right display.
Microsoft, there exist people that use more than your average user with a single C: drive that play Candy Crush on Facebook all day. And the limitations that you currently impose might very well be what keeps the Microsoft UWP applications from getting adopted. Because you know what? SMPlayer, a default application in any of my Linux workstation machines, it does handle such window transitions just fine!
Microsoft, I love how you at least gave us the option to enable Ctrl-Shift-C and Ctrl-Shift-V in WSL and conhost in general over that abomination that is Right-click and Return (those are so random!) that are relics from CP/M. But seriously? At this rate, I'd definitely not call it usable for anyone but those with a single monitor yet.
So please _/\_13 -
Just now I realized that for some reason I can't mount SMB shares to E: and H: anymore.. why, you might ask? I have no idea. And troubleshooting Windows.. oh boy, if only it was as simple as it is on Linux!!
So, bimonthly reinstall I guess? Because long live good quality software that lasts. In a post-meritocracy age, I guess that software quality is a thing of the past. At least there's an option to reset now, so that I don't have to keep a USB stick around to store an installation image for this crap.
And yes Windows fanbois, I fucking know that you don't have this issue and that therefore it doesn't exist as far as you're concerned. Obviously it's user error and crappy hardware, like it always is.
And yes Linux fanbois, I know that I should install Linux on it. If it's that important to you, go ahead and install it! I'll give you network access to the machine and you can do whatever you want to make it run Linux. But you can take my word on this - I've tried everything I could (including every other distro, custom kernels, customized installer images, ..), and it doesn't want to boot any Linux distribution, no matter what. And no I'm not disposing of or selling this machine either.
Bottom line I guess is this: the OS is made for a user that's just got a C: drive, doesn't rely on stuff on network drives, has one display rather than 2 (proper HDMI monitor recognition? What's that?), and God forbid that they have more than 26 drives. I mean sure in the age of DOS and its predecessor CP/M, sure nobody would use more than 26 drives. Network shares weren't even a thing back then. And yes it's possible to do volume mounts, but it's unwieldy. So one monitor, 1 or 2 local drives, and let's make them just use Facebook a little bit and have them power off the machine every time they're done using it. Because keeping the machine stable for more than a few days? Why on Earth would you possibly want to do that?!!
Microsoft Windows. The OS built for average users but God forbid you depart from the standard road of average user usage. Do anything advanced, either you can't do it at all, you can do it but it's extremely unintuitive and good luck finding manuals for it, or you can do it but Windows will behave weirdly. Because why not!!!12 -
Personal project: I design and build single-board computers with old processors like Z80, 6502 etc when I'm not being too lazy. A few run CP/M. One that's been more interesting in terms of digging deeper has been an 80C188, for which I've written a BIOS (despite the chip's built-in peripherals and interrupts being at non-standard addresses) mostly in C, which it can use to boot DOS from an image file on an SD card (bit-banged off the UART chip with FatFs). (Yes it's slow, but so is a 5.25" floppy.)
Work: My first project at my current job. Not particularly exciting compared to some stuff on here, but it got me into making useful contributions to the open-source CRM we used at the time. Was building a basic extension to deal with duplicated organisation names. So learned CiviCRM fairly deeply, a bit of Drupal, a bit of PHP. It's a shame we don't use that system any more, the community was cool.7 -
(first day at Command line)
cp /path/file
yes :) no destination..because Windows user algorithm
first ctrl+c then ctrl+v
took 2 hrs to figure out what's wrong
