Tried the below logic in windows form for file name incremental, if the file already exists in the specified path. but the files are created with the names "New1.txt2","New1.txt2.txt3". how the files can be created as "New1.txt", "New2.txt", "New3.txt"...."Newn.txt" on every button Click?
String filename =#"C:\path";
if (File.Exists(filename))
{
count++;
filename = filename + count.ToString()+".txt";
There is one more problem in your code. Why do you have file names like "New1.txt2","New1.txt2.txt3", "New1.txt2.txt3.txt4"? Because you don't keep initial filename somewhere. So, I'd propose to keep two variables for filenames: for instance, filename_initial and filename_current.
Try something like this:
String filename_initial = #"C:\path\New.txt";
String filename_current = filename_initial;
count = 0;
while (File.Exists(filename_current))
{
count++;
filename_current = Path.GetDirectoryName(filename_initial)
+ Path.DirectorySeparatorChar
+ Path.GetFileNameWithoutExtension(filename_initial)
+ count.ToString()
+ Path.GetExtension(filename_initial);
}

Hi I have a code that you can save file and give specific file naming.
the problem is how can I check if file exist in the folder directory.
What I'm trying to do is like this.
FileInfo fileInfo = new FileInfo(oldPath);
if (fileInfo.Exists)
{
if (!Directory.Exists(newPath))
{
Directory.CreateDirectory(newPath);
}
fileInfo.MoveTo(string.Format("{0}{1}{2}", newPath, extBox1t.Text + "_" + textBox2.Text + "_" + textBox3.Text, fileInfo.Extension));
im trying to add MessageBox.Show in the below
if (!Directory.Exists(newPath))
{
MessageBox.Show("File Exist. Please Rename!");
Directory.CreateDirectory(newPath);
But it does not work. Or is there a way to add extension name at the last part of filename it should like this
Example: STACKOVERFLOWDOTCOME_IDNUM_11162022_0
if STACKOVERFLOWDOTCOME_IDNUM_11162022 exist it will rename to STACKOVERFLOWDOTCOME_IDNUM_11162022_0
it will add _0 at the last part.
One way to do it is to write a method that extracts the directory path, name, and extension of the file from a string that represents the full file path. Then we can create another variable to act as the "counter", which we'll use to add the number at the end of the file name (before the extension). We can then create a loop that checks if the file exists, and if it doesn't we'll increment the counter, insert it into the name, and try again.
For example:
public static string GetUniqueFileName(string fileFullName)
{
var path = Path.GetDirectoryName(fileFullName);
var name = Path.GetFileNameWithoutExtension(fileFullName);
var ext = Path.GetExtension(fileFullName);
var counter = 0;
// Keep appending a new number to the end of the file name until it's unique
while(File.Exists(fileFullName))
{
// Since the file name exists, insert an underscore and number
// just before the file extension for the next iteration
fileFullName = Path.Combine(path, $"{name}_{counter++}{ext}");
}
return fileFullName;
}
To test it out, I created a file at c:\temp\temp.txt. After running the program with this file path, it came up with a new file name: c:\temp\temp_0.txt
I am reading files from a directory and reading all text and generating reports separately for each file. I want report name same as file name.
I have tried to get file name but when I pass it to reporting module it gives exception error.
string path = "D:\\AssertCount\\";
foreach (string sFile in Directory.EnumerateFiles(path))
{
assertCount=0;
reportingCounter++;
string[] files = Directory.GetFiles(path);
string fileName = files[reportingCounter];
}
ReportWriting(totalWords, assertCount,fileName);
here is complete report writing module
public static void ReportWriting(int totalWords, int assertCount,string fileName)
{
StreamWriter file = new StreamWriter("D:\\AssertCount\\Reports\\"+fileName+".txt");
file.Write("TotalWords = " + totalWords);
file.Write("\nAasserts = " + assertCount);
file.Write("\nOccurence of assert keyword in code is " + assertPercentage + " % ");
file.Close();
}
followin exception occurs
System.IO.IOException: 'The filename, directory name, or volume label syntax is incorrect : 'D:\AssertCount\Reports\D:\AssertCount\testData2.cpp.txt''
The issue is that Directory.EnumerateFiles() and Directory.GetFiles() return full paths, not file names. You could try replacing
string fileName = files[reportingCounter];
with
string fileName = Path.GetFileNameWithoutExtension(files[reportingCounter]);
to turn the full path into just the file name, without the extension (since you add on ".txt" later).
Alternatively, you're already enumerating the files in the directory with the foreach, so why not just use sFile?
foreach (string sFile in Directory.EnumerateFiles(path))
{
assertCount=0;
string fileName = Path.GetFileNameWithoutExtension(sFile);
ReportWriting(totalWords, assertCount,fileName);
}
You're duplicating the path:
'D:\AssertCount\Reports\D:\AssertCount\testData2.cpp.txt' (It should be just 'D:\AssertCount\testData2.cpp.txt'
The variable fileName already includes the full path to the resource (not only the file name). So you could just delete "D:\AssertCount\Reports\" from the creation of the StreamWriter object. The code would be like this
public static void ReportWriting(int totalWords, int assertCount,string fileName)
{
StreamWriter file = new StreamWriter(fileName+".txt");
file.Write("TotalWords = " + totalWords);
file.Write("\nAasserts = " + assertCount);
file.Write("\nOccurence of assert keyword in code is " + assertPercentage + " % ");
file.Close();
}
public static void CreateFolder()
{
string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory); //Gets desktop folder
string pathTo = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory) + "/" + "SYS_" + Random6CharString() + "/"; //Creates random directories
foreach(char path in Random6CharString())
{
System.IO.Directory.CreateDirectory(pathTo); //Method to create folders on Desktop
}
}
public static string Random6CharString()
{
string path = Path.GetRandomFileName();
path = path.Replace(".", ""); // Remove period.
return path.Substring(0, 6); // Return 6 character string
}
I'm making a game, and it should write folders to the users desktop to use as events on the game. When I get to a point, where 2 folders should be created simultaneously, it only creates one folder. Can anyone tell me how to make more than 1 folder at once? Or at least do them one after another instead of simultaneously? Thanks guys!
string pathTo = ...
foreach(char path in Random6CharString())
{
System.IO.Directory.CreateDirectory(pathTo); //Method to create folders on Desktop
}
You're using pathTo instead of the path variable of your foreach. So you're trying to create two folders with the same name in the same location (which it doesn't by the way, CreateDirectory can't overwrite an existing folder).
Look at your code:
string pathTo = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory) + "/" + "SYS_" + Random6CharString() + "/"; //Creates random directories
foreach(char path in Random6CharString())
{
System.IO.Directory.CreateDirectory(pathTo); //Method to create folders on Desktop
}
You're creating pathTo twice.
You could easily generate a random value for the path by using System.Guid.NewGuid(), by the way.
I am moving files from source folder to destination folder. Before moving files, I am checking that directory exists or not which is working fine. The issue is with my second check where I want to make sure that folder is not empty before moving files but it is not giving me correct result.
public void MoveFilesFromTempToSourceTbl()
{
//Moving all files from temp folder to orig folder.
string sourceFolder = (twitterDO.Path + "\\" + msgDate.Year.ToString() + "\\" + msgDate.Month.ToString() + "\\" + msgDate.Day.ToString() + "_Temp").Replace("\\", #"\");
string destinationFolder = (twitterDO.Path + "\\" + msgDate.Year.ToString() + "\\" + msgDate.Month.ToString() + "\\" + msgDate.Day.ToString()).Replace("\\", #"\");
string pattern = "*.txt";
if (Directory.Exists(sourceFolder))
{
if (File.Exists(pattern))
{
foreach (var file in new DirectoryInfo(sourceFolder).GetFiles(pattern))
{
file.MoveTo(Path.Combine(destinationFolder, file.Name));
}
}
if (Directory.GetFiles(sourceFolder).Length == 0) //Before deleting make sure that Temp folder is empty.
Directory.Delete(sourceFolder, true); // Delete Temp folder after moving all the contents.
}
}
I know I am making some small mistake but not sure what it is. Following is the screenshot of the result which I got in immediate window.

There's a bit of redundancy in your current code. Starting with the if-checks, here's how I would approach this:
var sourceDirectory = new DirectoryInfo(sourceFolder); // remember this, it is reused
if (sourceDirectory.Exists)
{
// Look for the files in the directory, if none found, will be empty array
foreach (var file in sourceDirectory.GetFiles(pattern))
{
file.MoveTo(Path.Combine(destinationFolder, file.Name));
}
// Re-check the directory for any remaining files
if (sourceDirectory.GetFiles(pattern).Length == 0) //Before deleting make sure that Temp folder is empty.
sourceDirectory.Delete(); // Delete Temp folder after moving all the contents.
}
As a small performance improvement, you could replace sourceDirectory.GetFiles() with sourceDirectory.EnumerateFiles() in the for-loop. This will allow you to start moving them as the method finds them, not after they have all been found.
You are passing "*.txt" into the File.Exists() call when you need to be passing a path.
You can read the Documentation here
Alternatively you could use something like this:
Directory.GetFiles(destinationFolder).Contains(filename)
I agree with David here but also I think the flow of you logic should be adjusted a bit. The File.Exixts(filename); should occur inside the foreach.
That will allow you to iterate each file and if it exists do something.
Try adding the following to check if any files exist in the location:
bool exist = Directory.EnumerateFiles(sourceFolder, "*.txt").Any();
How can I change the foldername if there exists some other folder with that name?
I tried in the below manner but it didn't work :(
private int ik;
protected void Button1_Click(object sender, EventArgs e)
{
string folderpath = #"C:\Users\nouser\Documents\Visual Studio 2010\WebSites\folders";
string foldername = TextBox1.Text;
string newPath = System.IO.Path.Combine(folderpath, foldername);
if (Directory.Exists(Path.Combine(folderpath, foldername)))
{
foldername = foldername + Convert.ToString(ik);
ik = ik + 1;
}
else
{
System.IO.Directory.CreateDirectory(newPath);
Response.Write("Folder created");
}
}
This code is able to create a new folder but unable to change the folder name from "newfolder" to "newfolder1" if "newfolder" already exists.
I'm assuming you want something where if you try to create a folder named "foo" but a folder named "foo" exist already you want your new folder to be called "foo1"? If so you'll have to detect if the folder exists or not and create a new name for it. You can do something like this
var count = 1;
var originalPath = newPath;
while(Directory.Exists(newPath)){
newPath = originalPath + count;
count++;
}
Directory.CreateDirectory(newPath);
This ensures that your new path doesn't already exist and if it does will ensure you get a unique name for your folder.
In your example I wasn't sure what you were doing with the variable
ik
I think thats where you were trying to create a unique directory, but what happens if you already have a newFolder1 there? This is why you should use a while loop to keep checking
Use system.IO.Directory move
System.IO.Directory.Move("newfolder","newfolder1");
For more information see msdn:
http://msdn.microsoft.com/en-us/library/system.io.directory.move.aspx
Use Move like this:
System.IO.Directory.Move("old name", "new name");
