Problems caused by improperly editing the Windows registry could render your computer operating system unusable. Microsoft provides a wealth of critical information that you need to know about the registry in the Microsoft Knowledge Base. Use the Microsoft Registry Editor only at your own risk and only after backing up the registry as outlined for your operating system in the Microsoft article How to back up and restore the registry in Windows and in the related solution How to back up the system registry.
Additional information about the registry is also contained in the Help topics in the Microsoft Registry Editor. Choose the Registry Editor. And i have to call this every time, and reallocate memory every time? That's no good. Presumably you'd have this variable length array at the end of hte structure, othersize i have to do math to read the subsequent fields.

Sadly even in the latest version Win10, the File Explorer itself still has problem dealing with long path name. Even "Copy as Path" in the context menu doesn't work as expected; it only copy the first chars. Make me wonder what is the point of this change. Note that the claim that the system setting is independent from the manifest setting is wrong.
Both are required. The policy has to be enabled at the system level and the manifest has to declare that the application is long-path aware. I read that making this change could cause compatibility issues with older bit applications, but is this type of problem with compatibility common? I'd like to make the change myself. KDP, it creates a compatibility problem with most bit programs, a lot of bit programs, and any other devices that aren't able to handle longer filenames i.
Synetech Things aren't that bad, because first of all the manifest controls if ONE concrete app is able to use longer paths or not at all. Second, to get a problem, you need longer paths for an app which doesn't support those anyway. BaCaRoZzo 7, 6 6 gold badges 48 48 silver badges 75 75 bronze badges. This needs to be run from an Administrator elevated command prompt. This will fail with forward slashes, needs to be backslashes. I am not sure if this applies to windows 10 only, however I just found that when trying to run this command, if I run as an administrator as suggested above the drive does not appear to be available.
This is because the behaviour appears to be similar to mapping a network drive and is session specific etc, so when I ran as an administrator and used this command, that session could use x: TL;DR If you can't see the drive try running the command without being in administrator mode. One way to cope with the path limit is to shorten path entries with symbolic links.
Didn't have to create the directory first, so step 1 is not necessary. This trick doesn't always work as many application try to resolve the links — nponeccop. It does not create a symbolic link. It's an important distinction since junction mountpoints are always evaluated on a server and must target local devices, while symbolic links are evaluated on the client and may target remote paths if allowed by policy.
Like a subst. DefineDosDeviceW , a junction target is typically limited to about 4K characters. It's actually 8K characters, split about evenly between the substitute path and the display path. Add a comment. Peter Mortensen Each application still has to declare that it's long-path aware. Microsoft has done a poor job communicating this by making it seem like the application manifest is just another way to enable this feature, rather than clearly explaining that it's a contract between the OS system level policy and application in which both have to agree.
Even Visual Studio Community doesn't support long paths, sadly — Pieterjan. Conrad Conrad 2, 27 27 silver badges 47 47 bronze badges. Short path names can be disabled in the registry or was it the filesystem itself? Generating short names can be disabled for NTFS and should be because it's inefficient in many cases , either for the whole system or per volume, so it is an unreliable approach even for paths on the system drive, which must be NTFS.
MS has no plans to deprecate this feature. I still say to just use non-normalized device paths i. As to newer filesystems, we probably wouldn't see software installed on an exFAT volume, other than portable applications, since it has no security, but I wouldn't rule out ReFS. Users install programs in non-standard locations for reasons of convenience, space, or performance.

It's just that the property of a folder in Windows only reports the number of folder and files that don't violate the limitation.
