file-exists

I am trying to determine if a file exists in a network folder: // File name is "\\QWERTY\folder\dir\A123456.TXT" Path path = Paths.get("\\\\QWERTY\\folder\\dir\\A123456.TXT") Using NIO Files : Files.exists(path) == false Using File : path.toFile().exists() == true Using File seems to be the correct one according to our tests. Why does File work better than Files ? So, which is it? Can't be both! But wait, there is also Files.notExists(path) . When the network share file actually exists Files.exists(path): false Files.notExists(path): false path.toFile().exists(): true When the network share

I am working on an application. That application should get the resume from the users, so that I need a code to verify whether a file exists or not. I'm using ASP.NET / C#. You can determine whether a specified file exists using the Exists method of the File class in the System.IO namespace: bool System.IO.File.Exists(string path) You can find the documentation here on MSDN . Example: using System; using System.IO; class Test { public static void Main() { string resumeFile = @"c:\ResumesArchive\923823.txt"; string newFile = @"c:\ResumesImport\newResume.txt"; if (File.Exists(resumeFile)) { File

To read a file in Android from your app's private storage area you use the function openFileInput() . My question is, is there a way to check if this file exists before calling this function? The function can throw a FileNotFoundException , but I feel like calling this and then doing something based on a try - catch is a bad practice. Using File.exist() seems like a strange thing to use also since it would require instantiating a class and I am not sure if just passing the name of the file to it would get it to find the file in the private area of my phone. coder_For_Life22 public boolean

I'm trying to rename the file name of an image when it's uploaded if it exists, say if my file name is test.jpg and it already exists I want to rename it as test1.jpg and then test2.jpg and so on. With the code I've written its changing my file name like so test1.jpg and then test12.jpg any advice on fixing this would be great thank! PHP $name = $_FILES['picture']['name']; $actual_name = pathinfo($name,PATHINFO_FILENAME); $extension = pathinfo($name, PATHINFO_EXTENSION); $i = 1; while(file_exists('tmp/'.$actual_name.".".$extension)) { $actual_name = (string)$actual_name.$i; $name = $actual

How can I check if a file exists using Lua? Try function file_exists(name) local f=io.open(name,"r") if f~=nil then io.close(f) return true else return false end end but note that this code only tests whether the file can be opened for reading. Using plain Lua, the best you can do is see if a file can be opened for read, as per LHF. This is almost always good enough. But if you want more, load the Lua POSIX library and check if posix.stat( path ) returns non- nil . tDwtp I will quote myself from here I use these (but I actually check for the error): require("lfs") -- no function checks for

I want to check to see if a file exists in a particular folder from SSIS. How can I accomplish this? Variables: folder - string - C::\Temp\ file - string - 1.txt fileExists - boolean - False public void Main() { string folder = Dts.Variables["User::folder"].Value.ToString(); //@"C:\temp\"; string file = Dts.Variables["User::file"].Value.ToString(); //"a.txt"; string fullPath = string.Format(@"{0}\{1}", folder, file); Dts.Variables["User::fileExists"].Value = File.Exists(fullPath); Dts.TaskResult = (int)ScriptResults.Success; } You can use Foreach Loop Container and simply place all your items
