You had no chance to continue using your computer. mp3! in IRC was an order to play instantly a sound remotely, if you got the same sound in your computer it played remotely, so, if you put a forbidden name into the file to play, it crashed remote computer instantly. There was a fix in 2000 for it. Windows Me had the bug corrected. Other names were exactly the same and CLOCK$ IFS$HLP$ too.

[@cuteswan]

If you get stuck with a path length limit you can open a command prompt and use the SUBST command to map a drive letter to somewhere deep enough in the path tree. Then you can use Explorer to move (or shorten the names of) files and folders until the items are within the limit for the actual drive/volume. This will help get you out of a jam, but I *strongly* recommend against using SUBST as a permanent solution. IIRC you can also share one of the folders in the tree and it will pretty much work the same.

[@grn1]

I could've used this advice many years ago. I don't even think it was caused by Linux but rather that Windows had allowed me to copy the files/folders in the first place.

[@spvillano]

I've used that quite a few times to get out of a jam. I've also caught malware using metafiles, even volume shadow copy functions. I've also did a net use UNC path to drive mount to get around an obscenely long path. I've also been known to do things like copy con > com1 ath0 ^Z the carat denoting control... Useful for things like label printer initialization strings, when nothing else works to reset and reinitialize the damnable temperamental things.

1:00 - The reason that some Unicode characters don't work either is because Windows treats filenames with "special" (read non-ASCII) characters as long-filenames even if they're not literally "long", and when it tries to create a short-filename (8.3) entry for it, it tries to use the closest substitutes for them that it can, so when you try to create a file called LPT¹, it tries to create a SFN called LPT1 which isn't allowed, so it fails. The LFN-SFN substitution mapping has limits, so some do work. 3:00 - It's not just empty files that are stored directly in the MFT instead of in clusters, even small (

4:00 more on this, I guess: in (as far as I know) all modern filesystems, folders and files are basically the same thing - folders are just files that contain references to other files. this lets the computer treat them more or less the same, and also that all of the usual naming restrictions on files also applies to folders.

[@OttoWerse]

Fun fact: Some versions of the default Android Camera App used "aux.jpg" as the name for low-resolution previews of some images, so if you had set up automatic backups in Google Drive/Google Photos on a device with that version installed, it would create lots of undeletable files on any Windows PC that was set up to sync your Google Drive folder.

[@kikixchannel]

Possible to work around by using a tree of shortcuts instead of an actual folder, with the files and folders themselves just being in limited few directories (few because having just one folder with 'everything' is a technical issue in and off itself).

[@TheCandoRailfan]

On Windows 11, I was able to use the command prompt to rename an existing text file to LPT1.txt. Windows 11 also had no issues opening, deleting, copying, etc. the file. Out of curiosity I decided to copy it onto a USB, and plug it into a Windows XP laptop. There, it had the issues with copying it and deleting, etc. Windows XP's command prompt also did not allow renaming a file to LPT1.txt. TL;DR, on Windows 11, using these file names works better than on older versions of Windows.

in macOS the only forbidden characters in file names are ":" and "/".

It was for controlling the particle effect that played when the player died by walking into a nanorobot swarm trap and it caused the nanites particles to swarm around the player, block the cameras view, then despawned the player, spawned in some fake dead player body parts, and then dispersed the nanites. The result was that it really did look like the player was being eaten by nanites.

It is even possible to copy those long paths via Explorer using two windows and copy file by file if neccessary. To copy those folders Windows has the on-board tool ROBOCOPY.

Serial uses both DB9 and DB25. DB25 allowed one to have two serial connections on one cable and a few other tricks from the old serial terminal days. After all, the only way for the longest time to use a mainframe was via a serial terminal. So, buildings were festooned internally with 25 pin cables and occasionally even connectors in the walls, leading to a mux (multiplexer) room, which connected to the mainframe. Later came ethernet or broken ring with fat cabling, ethernet using coax mostly, with vampire taps. Boy, was that ugly at times!

I'm not sure how related it is to these forbidden names but there's one other filename limitation I know of in Windows. I don't know if it's related to "." and ".." being treated as actual files but you can't start a file or folder name with a period. There's an exception to this, however, if you end it with a period as well (after the file extension for files), then it will create it with the period at the beginning. An oddity with files in particular is that Windows will ask if you want to change the file extension but it actually doesn't do so. It also has another oddity in that if you then try to rename it, it only has the beginning period so you have to add the one at the end again. I actually have no idea why this happens but it's interesting.

At one time the nul device existed on ALL directories. Back in the day, we would redirect all output being set to & from the device CON if all we needed was the data that was written to a separate file that we could use.

As an IT professional: The file length limit is not a edge limit. Some customers just seem to thrive on overly long and complex folder structures. Luckily, the long file name support can also be enabled per GPO.

[@shr1han]

In a VM, I tried to install win10 and created something using the forbidden characters by booting into a Linux Live CD. All were behaving really differently. If I tried to create a folder named C:, Windows would take me to C:\ (i.e. the actual C: drive), and if I try to delete that from within Windows, it would actually try to delete the actual C: drive! Second, if I try to create folders with / and \, some made Windows refuse it's existence and some make explorer to take me into that path, e.g. if I create a folder named Windows\ in the C: drive, it would take me to the actual Windows folder. And again, deleting them would try to delete C:\Windows. Third, I tried to make folders with double quotes and Windows refused it's existence and some gave weird errors like ERROR: CRITICAL ERROR (the descriptive error name ever). Creating folders with < or > in the name did kinda the same thing as the others, but creating two folders, one with < and another with > in Desktop (say), I couldn't get access to the Desktop; when I log in to Windows, it gave me an error saying it couldn't access it. HERE'S THE SCARIEST PART: I CREATED THE TWO FOLDERS WITH < AND > IN THE ROOT OF C:\ DRIVE AND..... GUESS WHAT, IT RENDERED THE OS UNBOOTABLE! Automatic "Repair" didn't work either as it couldn't actually access the C: drive to perform repairs. The only solution was to delete the folders from within Linux Live CD.

0:09 Funnily enough, you can create them with software written to create files with those names. The blacklist seems to be at shell level (Explorer, standard save dialogs, etc.), not on the WinAPI level.
