I need to get path for each file in directories
eg: c:/a/b/c/1.jar and c:/dir/bin/2.jar must be saved as string
"c:/a/b/c/1.jar; c:/dir/bin/2.jar;..."
But the folders name may change in the future and I don't want to write this manually
Thanks for help
EDIT 1:
I've got the folder with few folders into. in each folder is files. I need to get all files directory in one string. eg: "dir1; dir2; dir3; ..."
but I can give only directory of main folder "c:/bin"
EDIT 2: Solved by Sayse
You can use Directory.EnumerateFiles
var allFiles = Directory.EnumerateFiles(sourceDirectory,
"*.*", //also can use "*.jar" here for just jar files
SearchOption.AllDirectories);
If you wish for all files to be in one long string then you can use
var fileString = string.Join(",", allFiles);
If its only directories you want
var allDirs = Directory.EnumerateDirectories("...",
"*",
SearchOption.AllDirectories);
var dirString = string.Join(";", allDirs);
class Program
{
static void Main(string[] args)
{
DirectoryInfo di = new DirectoryInfo("C:\\");
FullDirList(di, "*");
Console.WriteLine("Done");
Console.Read();
}
static string myfolders = "";// Your string, which inclueds the folders like this: "c:/a/b/c; c:/dir/bin;..."
static string myfiles = ""; // Your string, which inclueds the file like this: "c:/a/b/c/1.jar; c:/dir/bin/2.jar;..."
static List<FileInfo> files = new List<FileInfo>(); // List that will hold the files and subfiles in path
static List<DirectoryInfo> folders = new List<DirectoryInfo>(); // List that hold direcotries that cannot be accessed
static void FullDirList(DirectoryInfo dir, string searchPattern)
{
// Console.WriteLine("Directory {0}", dir.FullName);
// list the files
try
{
foreach (FileInfo f in dir.GetFiles(searchPattern))
{
//Console.WriteLine("File {0}", f.FullName);
files.Add(f);
myfiles += f.FullName + ";";
}
}
catch
{
Console.WriteLine("Directory {0} \n could not be accessed!!!!", dir.FullName);
return; // We alredy got an error trying to access dir so dont try to access it again
}
// process each directory
// If I have been able to see the files in the directory I should also be able
// to look at its directories so I dont think I should place this in a try catch block
foreach (DirectoryInfo d in dir.GetDirectories())
{
myfolders += d.FullName + ";";
folders.Add(d);
FullDirList(d, searchPattern);
}
}
}
myfiles includes all files , like "C:\MyProgram1.exe;C:\MyFolder\MyProgram2.exe;C:\MyFolder2\MyProgram2.dll"
myfolder inclueds all folders, like "C:\MyFolder;C:\MyFolder2";

How to delete Files there names containing a specific string in a Directory and also all Subdirectories?
Given Filenames like:
EA myown EURJPY M15 3015494.mq5
EA myown EURJPY M15 3015494.ex5
EA self EURJPY M15 3098111 fine.mq5
EA self EURJPY M15 3098111 fine.ex5
Given Folderstructures like:
D:\TEMP\MYTEST
D:\TEMP\MYTEST\EURJPY
D:\TEMP\MYTEST\EURJPY\EURJPY_M15
Example: I want to delete ALL Files in all Subdirectories containing this String:
3015494
These Files are copied more than one time down of the Root-Folder "D:\TEMP\MYTEST" and also copied into the Subdirectories.
I try to write a little function for this. But i can delete Files into a given Folder, but not down into Subfolders ...
Last Code from me:
// call my function to delete files ...
string mypath = #"D:\TEMP\MYTEST\";
string myfilecontains = #"xx";
DeleteFile(mypath, true, myfilecontains);
// some code i found here and should delete just Files,
// but only works in Root-Dir.
// Also will not respect my need for Filename contains Text
public static bool DeleteFile(string folderPath, bool recursive, string FilenameContains)
{
//Safety check for directory existence.
if (!Directory.Exists(folderPath))
return false;
foreach (string file in Directory.GetFiles(folderPath))
{
File.Delete(file);
}
//Iterate to sub directory only if required.
if (recursive)
{
foreach (string dir in Directory.GetDirectories(folderPath))
{
//DeleteFile(dir, recursive);
MessageBox.Show(dir);
}
}
//Delete the parent directory before leaving
//Directory.Delete(folderPath);
return true;
}
What i have to change in this Code for my needs?
Or is there a complete different code something more helpfull?
I hope you have some good ideas for me to catch the trick.
DirectoryInfo dir = new DirectoryInfo(mypath);
// get all the files in the directory.
// SearchOptions.AllDirectories gets all the files in subdirectories as well
FileInfo[] files = dir.GetFiles("*.*", SearchOption.AllDirectories);
foreach (FileInfo file in files)
{
if (file.Name.Contains(myfilecontains))
{
File.Delete(file.FullName);
}
}
This is similar to hossein's answer but in his answer if the directory name contains the value of myfilecontains that file will get deleted as well which I would think you don't want.
//get the list of files in the root directory and all its subdirectories:
string mypath = #"D:\TEMP\MYTEST\";
string myfilecontains = #"xx";
var files = Directory.GetFiles(mypath, "*", SearchOption.AllDirectories).ToList<string>();
//get the list of file for remove
var forDelete = files.Where(x => x.Contains(myfilecontains));
//remove files
forDelete.ForEach(x => { File.Delete(x); });
hope this helps!
So this seems to me to be a simple looping issue it's just that I keep confusing myself over the logic.
So I want to count all the files within a folder, and then all the folders within that folder, I want to count the files that are in there too.
Which mean I have to loop through to check wether there is a folder and then check it until there are no more folders. But I can't write the algoritm because I keep confusing myself.
I'm pretty sure there is a standard algorithm for something like this but I can't remember the name.
This is what I have so far:
var rootDir = Directory.GetDirectories(#"C:\");
foreach (var dir in rootDir)
{
if (Directory.GetDirectories(dir).Length > 0)
{
}
}
Do I understand right, you need to count only files in folder and all subfolders? Directory.GetFiles has option for review all subfolders. Try this
Directory.GetFiles(WorkingDir, "*", SearchOption.AllDirectories);
use GetFiles
Directory.GetFiles
// Process all files in the directory passed in, recurse on any directories
// that are found, and process the files they contain.
public static void ProcessDirectory(string targetDirectory)
{
// Process the list of files found in the directory.
string [] fileEntries = Directory.GetFiles(targetDirectory);
foreach(string fileName in fileEntries)
ProcessFile(fileName);
// Recurse into subdirectories of this directory.
string [] subdirectoryEntries = Directory.GetDirectories(targetDirectory);
foreach(string subdirectory in subdirectoryEntries)
ProcessDirectory(subdirectory);
}
// Insert logic for processing found files here.
public static void ProcessFile(string path)
{
Console.WriteLine("Processed file '{0}'.", path);
}
here is a solution to count all files files and number of file per dir: i am using a dictionary to stock all datas
class Program
{
public static Dictionary<string, int> dico = new Dictionary<string, int>();
public static void CountFiles(string nameDirectory)
{
int nbrfiles = Directory.GetFiles(nameDirectory).Length;
dico[targetDirectory] = nbrfiles;
string[] subdirectories = Directory.GetDirectories(nameDirectory);
foreach (string subdir in subdirectories)
CountFiles(subdir);
}
static void Main(string[] args)
{
string tdir = "e:\\example";
CountFiles(tdir);
var totalfiles = dico.Sum(x => x.Value);
Console.WriteLine($"Directory {tdir} contains {totalfiles} files");
foreach (var item in dico)
{
Console.WriteLine($"Directory {item.Key} has {item.Value} file(s)");
}
}
}
So basically i am making an app that will sync file types is different ways, I want to search the whole of a logical Drive for example C:\ for all text files.How ever once i find all the text files i want to apply an action for example move all text files to one location or email all text files to the users email.
I have found this code from a past Stack overflow post
public List<string> Search()
{
var files = new List<string>();
foreach (DriveInfo d in DriveInfo.GetDrives().Where(x => x.IsReady))
{
try
{
files.AddRange(Directory.GetFiles(d.RootDirectory.FullName, "*.txt", SearchOption.AllDirectories));
}
catch(Exception e)
{
Logger.Log(e.Message); // Log it and move on
}
}
return files;
}
But what i want to know is how do i do somthing when i find the files ?
The code you posted looks like it should fill List<string> files with strings representing names of files that have a .txt extension.
It should be as simple as iterating over the value returned from the function and doing as you please with them.
This code should (untested) check for a target directory, create it if it doesn't exist, and then copy each file returned from Search() to the target path.
List<string> results = Search();
String targetPath = "C:/TargetDirectory/";
if (!System.IO.Directory.Exists(targetPath))
System.IO.Directory.CreateDirectory(targetPath);
foreach (string aFileStr in results)
{
String sourceFile = aFileStr;
String destFile = Path.Combine(targetPath, Path.GetFileName(aFileStr));
System.IO.File.Copy(sourceFile, destFile, true);
}
You would do a foreach on the list of strings that that function returns.
I'm not quite sure if I understand you correctly. If you just want to know how to process your filelist, you could for instance do the following:
var filelist = Search();
foreach (var s in filelist) {
string fn = System.IO.Path.GetFileName(s);
string dest = System.IO.Path.Combine("c:\\tmp", fn);
System.IO.File.Copy(s, dest, true);
}
which will copy all files in filelist to c:\tmp and overwrite files with equal filename.
I'm trying this function, which copies all files from a folder, and relative subfolders with files to another location:
using System.IO;
private static bool CopyDirectory(string SourcePath, string DestinationPath, bool overwriteexisting)
{
bool ret = true;
try
{
SourcePath = SourcePath.EndsWith(#"\") ? SourcePath : SourcePath + #"\";
DestinationPath = DestinationPath.EndsWith(#"\") ? DestinationPath : DestinationPath + #"\";
if (Directory.Exists(SourcePath))
{
if (Directory.Exists(DestinationPath) == false)
Directory.CreateDirectory(DestinationPath);
foreach (string fls in Directory.GetFiles(SourcePath))
{
FileInfo flinfo = new FileInfo(fls);
flinfo.CopyTo(DestinationPath + flinfo.Name, overwriteexisting);
}
foreach (string drs in Directory.GetDirectories(SourcePath))
{
DirectoryInfo drinfo = new DirectoryInfo(drs);
if (CopyDirectory(drs, DestinationPath + drinfo.Name, overwriteexisting) == false || drs.Substring(drs.Length-8) == "archive")
ret = false;
}
}
else
{
ret = false;
}
}
catch (Exception e)
{
Console.WriteLine("{0} {1} {2}", e.Message, Environment.NewLine + Environment.NewLine, e.StackTrace);
ret = false;
}
return ret;
}
It works good until you have to copy the folder into another location, but when you have to create a folder in itself (In my example I'm doing a subfolder called "archive" to keep track of the last folder files changes) it goes in infinite loops, because it keeps rescanning itself in the Directory.GetDirectories foreach loop, finding the newly created subfolders and going on nesting the same subfolder over and over until it reaches a "Path name too long max 260 charachters limit exception".
I tried to avoid it by using the condition
|| drs.Substring(drs.Length-8) == "archive")
which should check the directory name, but it doesn't seem to work.
I thought than, different solutions like putting a max subfolders depth scan (I.E max 2 subfolders) so it doesn't keep rescanning all the nested folders, but I can't find such property in Directory object.
I cannot copy the whole thing to a temp folder and then into the real folder because the next time I will scan it, it will rescan archive folder too.
I tought about putting all the directory listing in an ArrayList of Directory objects or so so maybe I can check something like DirName or so but I don't know if such property exists.
Any solution?
This is a case where recursion doesn't really work, as the list of directories and files always changes as you copy. A better solution is to get the list of all files and folders in advance.
You can get all files and directories in a tree using the Directory.GetFiles(String,String,SearchOption) and Directory.GetDirectories(String,String,SearchOption) with SearchOption set to SearchOption.AllDirectories. These will return all files and all directories respectively.
You can follow these steps to copy the files:
Get the list of all source directories and sort them in ascending order. This will ensure that parent directories appear before their child directories.
Create the target directory structure by creating the child directories in their sorted order. You won't get any path conflicts as the sort order ensures you always create the parent folders before the child folders
Copy all the source files to the target directories as before. Order doesn't really matter at this point as the target directory structure already exists.
A quick example:
static void Main(string[] args)
{
var sourcePath = #"c:\MyRoot\TestFolder\";
var targetPath = #"c:\MyRoot\TestFolder\Archive\";
var directories=Directory.GetDirectories(sourcePath, "*", SearchOption.AllDirectories);
var files = Directory.GetFiles(sourcePath, "*", SearchOption.AllDirectories);
if(!Directory.Exists(targetPath))
Directory.CreateDirectory(targetPath);
foreach (var directory in directories)
{
var relativePath = GetRelativePath(sourcePath, directory);
var toPath = Path.Combine(targetPath, relativePath);
if (!Directory.Exists(toPath))
{
Directory.CreateDirectory(toPath);
}
}
foreach (var file in files)
{
var relativePath = GetRelativePath(sourcePath, file);
var toPath = Path.Combine(targetPath, relativePath);
if (!File.Exists(toPath))
File.Copy(file,toPath);
}
}
//This is a very quick and dirty way to get the relative path, only for demo purposes etc
private static string GetRelativePath(string rootPath, string fullPath)
{
return Path.GetFullPath(fullPath).Substring(rootPath.Length);
}
I can do this so simply with files, like so:
public static void MoveAllFilesFromDesktopToJDrive()
{
DirectoryInfo di = new DirectoryInfo(#"C:\Users\Tafe\Desktop\");
DirectoryInfo Jdrive = new DirectoryInfo(#"J:\");
foreach (FileInfo fi in di.GetFiles())
{
if (Path.GetFileName(fi.FullName) != "desktop.ini")
{
fi.MoveTo(Jdrive.FullName + Path.GetFileName(fi.FullName));
}
}
}
But trying the same operation on directories tells me I can't move directories accross volumes. OK then, so this is what I've tried:
public static void MoveAllDirsFromDeskTopToJDrive()
{
DirectoryInfo di = new DirectoryInfo(#"C:\Users\Tafe\Desktop\");
DirectoryInfo Jdrive = new DirectoryInfo(#"J:\");
foreach (DirectoryInfo dirs in di.GetDirectories())
{
Directory.CreateDirectory(Jdrive + Path.GetFileName(dirs.FullName));
}
}
This copies the names of the files, but not the contents, I would just move the contents like I did with my MoveAllFilesFromDesktopToJDrive() method, but the directories contain subdirectories and subdirectories and such, so I can't figure it out. I know a TINY bit about recursion, but not enough to even attempt this. Also, It can't be that hard can it? There has to be something better in the API to facilitate this? If not, any help to complete this method MoveAllFilesFromDesktopToJDrive() would be a lifesaver!
Try looping this somewhere within your code:
string fileName = "test.txt";
string sourcePath = #"C:\Users\Public\TestFolder";
string targetPath = #"C:\Users\Public\TestFolder\SubDir";
// Use Path class to manipulate file and directory paths.
string sourceFile = System.IO.Path.Combine(sourcePath, fileName);
string destFile = System.IO.Path.Combine(targetPath, fileName);
// To copy a folder's contents to a new location:
// Create a new target folder, if necessary.
if (!System.IO.Directory.Exists(targetPath))
{
System.IO.Directory.CreateDirectory(targetPath);
}
System.IO.File.Copy(sourceFile, destFile, true);
