How does Java circumvent the windows MAX_PATH WinAPI limitation

问题 Does anyone know how Java is able to circumvent the windows MAX_PATH limitations. Using the below code I was able to create a really long path in Java and was able to perform I/O, which would have been impossible using windows without prefixing \\?\. public static void main(String[] args) throws IOException { BufferedWriter bufWriter = null; try { StringBuilder s = new StringBuilder(); for (int i = 0; i < 130; i++) { s.append("asdf\\"); } String filePath = "C:\\" + s.toString();; System.out

How do I get in python the maximum filesystem path length in unix?

问题 In the code I maintain I run across: from ctypes.wintypes import MAX_PATH I would like to change it to something like: try: from ctypes.wintypes import MAX_PATH except ValueError: # raises on linux MAX_PATH = 4096 # see comments but I can't find any way to get the value of max filesystem path from python ( os, os.path, sys... ) - is there a standard way or do I need an external lib ? Or there is no analogous as MAX_PATH in linux, at least not a standard among distributions ? Answer try: MAX

Accessing files beyond MAX_PATH in C#/.NET

问题 BACKGROUND I need to write a tool using .NET version 2.0 at highest (using something off the shelf is not an option for this client for political, commercial, and confidentiality/trust reasons) to migrate files from one server to another over the network. The servers are file servers for local teams, and certain team folders need to be migrated to other servers to facilitate a reorganisation. The basic idea is we read each file and stream it over the network out of hours and after a few days

How to get CreateProcess/CreateProcessW to execute a process in a path > MAX_PATH characters

由 随声附和 提交于 2019-12-12 16:18:27
问题 I'm trying to get either CreateProcess or CreateProcessW to execute a process with a name < MAX_PATH characters but in a path that's greater than MAX_PATH characters. According to the docs at: http://msdn.microsoft.com/en-us/library/ms682425.aspx, I need to make sure lpApplicationName isn't NULL and then lpCommandLine can be up to 32,768 characters. I tried that, but I get ERROR_PATH_NOT_FOUND. I changed to CreateProcessW, but still get the same error. When I prefix lpApplicationName with \\?

Powershell: 'The fully qualified file name must be less than 260 characters'

问题 I tried to use powershell command copy-item as xcopy to copy content of one disk to another one. copy-item -Path h:\* -Destination g:\ -Recurse -Force However, I encountered the following errors: Copy-Item : The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters. I got these errors enough to discourage manually search and copy files or folders with long paths. What is the best

Resolving long path (>260 char) limitation for accessing files/folders in latest Windows 10 build using Javascript

由 [亡魂溺海] 提交于 2019-12-07 15:38:26
I am building a cordova windows application and get an error in accessing files and folders from my application that have path lengths greater than 260 characters because of the windows limitation. For accessing or creating new files and folders, currently, I am using Windows.Storage namespace of Windows (Runtime) API for Javascript with functions such as createFolderAsync, getFolderAsync, getFileFromPathAsync etc. Recently, I heard that the latest build of Windows 10 has removed the 260 character limit for paths of files/folders. (Here is the link ) But this is only available in some

C++ WinAPI: handling long file paths/names

由 蓝咒 提交于 2019-12-01 04:06:50
I'm looking at handling longer file paths in my windows application. Currently, I have a text box (edit box) in which a user can type an absolute file path. I then read that typed file path, using GetWindowText , into a string declared like so: TCHAR FilePath[MAX_PATH]; Obviously, here i'm relying on the MAX_PATH constant which limits me to 260 chars. So to handle longer file/paths names could I just extend my TCHAR array like this: TCHAR FilePath[32767]; . Or is there a better way? Could I use a variable length array? ( TCHAR FilePath[]; is this even possible in C++? - sorry i'm pretty new to
