I have never been a fan of hardcoding MAX_PATH but I have seen it a lot.

Now to the dangerous: I am perfectly aware that the only problem is array sizes. I only wanted to make clear that I only looked for C++ projects. For functions that return a file name, such asР’В GetFullPathName function, you specify a buffer size. No configuration or specialР”Р„llocation necessary. If you provide a string with a long file name then C (and of course C++) will automatically handle it. Most of them, likeР’В CreateFile function, get a string that is null-terminated.

If the C# compiler does not support it then you can call Windows using 'interop' (DllImport) but I don't know if the manifest is a problem. For functions that return a file name, such as GetFullPathNameР”Р„s for C#, you did not say anything about C#. No configuration or special allocation necessary. Then C (and of course C++) will automatically handle it. If you provide a string with a long file name Most of them, like CreateFile function, get a string that is null-terminated. The only danger is if a program does not allow sufficient memory for a file name, but see below. Since I could not find a setting in Visual Studio, which enables this (I only looked for C++ applications, not C#), I daresay, I have to add this manually to the manifest.

That is way more than I have hoped for and quite useful, especially for portable apps.

If I understand that correctly, I can use this feature on any reasonable recent Windows 10 version without the owner having to temper with the registry or GPO. 'You can also enable the new long path behavior per appР’В via the manifest: true The more interesting news for me is this:

Microsoft has listed the functions and someone else has already quoted that, so no point in doing it again. Enabling long paths via GPO or registry hack enables this feature. Therefore, programs have to actually opt-in via manifest. Even if you enable it, programs cannot just use it, for they are likely to have used a fixed-size array to store Since long paths are potentially dangerous, not yetР’В well tested and not properly supported by File Explorer, it is disabled by default.

My original understanding of this matter was as follows: I had to Google for something much, much less narrow but I got something useful out of it. These are the file management functions that no longer have MAX_PATH restrictions if you opt-in to long path behavior: CopyFileW, CopyFile2, CopyFileExW, CreateFileW, CreateFile2, CreateHardLinkW, CreateSymbolicLinkW, DeleteFileW, FindFirstFileW,Р”Р‡indFirstFileExW, FindNextFileW, GetFileAttributesW, GetFileAttributesExW, SetFileAttributesW, GetFullPathNameW, GetLongPathNameW, MoveFileW, MoveFileExW, MoveFileWithProgressW, ReplaceFileW, SearchPathW, FindFirstFileNameW, FindNextFileNameW, FindFirstStreamW,Р”Р‡indNextStreamW, GetCompressedFileSizeW, GetFinalPathNameByHandleW.Р”Р„fter posting this question, I have continued my research and found the sameР’В resource someone else has used in his answer. These are the directory management functions that no longer have MAX_PATH restrictions if you opt-in to long path behavior: CreateDirectoryW, CreateDirectoryExW GetCurrentDirectoryW RemoveDirectoryW SetCurrentDirectoryW. The major point of my posts is to aid in the learning process.

I may also give inefficient code or introduce some problems to discourage copy/paste coding. They are meant to just illustrate a point. Any samples given are not meant to have error checking or show best practices. This manifest will now be merged with your main application manifest. Third go to the project properties and add this manifest under the manifest tool. Notice that this is only the portion of the manifest that you want to add. Second, open the file that you created and insert the following portion of a manifest file. First, in your project add a text file and name it something like addition.manifest (yes, changing the extension). Then true to Microsoft's style, the MSDN documentation documented this as an either or thing, so there has been confusion about this since theР”Р„nyway, to add this to the manifest is easy. Original blog post that documented this did clearly state that both the GPO and the manifest were both needed.
