I use p.basename from flutter path library to get file name, but i got it with extension, how to remove extension? also to get path I use getApplicationDocumentsDerectory from path_provider library
File newFile = File(filepath);
String name = p.basename(newFile.path);
this is code I use to get file name
You just use 'basenameWithoutExtension' method like basename.
File newFile = File(filepath);
String name = p.basename(newFile.path);
String nameWithoutExtension = p.basenameWithoutExtension(newFile.path);

String fileName = _profPic.path.split('/').last;
print(fileName);
Output is Screenshot_2020-05-12-17-14-07-564_com.miui.home.png
but I require only home.png
It's impossible path or dart can decide which parts of the name you need.
You must manipulate the string. In your case, this method will do what you need:
String getName(String fullName){
final parts = fullName.split('.');
return parts.skip(parts.length - 2).take(2).join('.');
}
example:
final name = 'Screenshot_2020-05-12-17-14-07-564_com.miui.home.png';
print(getName(name)); // home.png
Or, you can convert this method into an extension.
I have my files saved on resources folder and when I try to write other thing it does not work. Could anyone help me?
public void SaveGameData()
{
PlayerSavedData aux = new PlayerSavedData();
aux.allSavedPlayerData = SavePlayerInformation.playerDataList.ToArray<PlayerData> ();
string dataAsJson = JsonUtility.ToJson (aux);
string filePath = Application.persistentDataPath + "playerInformation.json";
File.WriteAllText (filePath, dataAsJson);
}
This is wrong
string filePath = Application.persistentDataPath + "playerInformation.json";
Try this instead
string filePath = Path.Combine(Application.persistentDataPath,"playerInformation.json");
Also note that you need WRITE_EXTERNAL_STORAGE permission
The Resoures folder simply doens't exist any more afer your build. The assets in the Resources folder get packed into the game's archive for assets.
Better you put file in StreamingAssets folder.
I am trying to copy a file from one dir to another using the copyFile(path, fileName, newPath, newFileName) function. It gives an error like {"code":13, "message":"input is not a directory"}. The documentation has only 12 error code and no 13th. I'd like to know what i did wrong please.
Here is a sample of my actual code.
this.path = "file:///storage/emulated/0/TheFolder/thefile.ext";
this.newPath = "file:///storage/emulated/0/NewFolder";
this.fileCtrl.copyFile(this.path, fileName, this.newPath, newFileName)
this.path must be a directory but your are showing some file name
change your code as follows
this.path = "file:///storage/emulated/0/TheFolder";
this.newPath = "file:///storage/emulated/0/NewFolder";
this.fileCtrl.copyFile(this.path, YOUR_EXISTING_FILE_NAME, this.newPath, NEW_FILE_NAME);
path -Base FileSystem
fileName - Name of file to copy
newPath - Base FileSystem of new location
newFileName - New name of file to copy to (leave blank to remain the same)
In my application, I have files in FTP server one directory and I move that file source to target path. In this process, when I move selected source file that source file will not show in the source path, it will show only in target path.
I tried this below code, but I am getting error:
string sourceurl = "ftp://ftp.com/Mainfoder/Folder1/subfolder/subsubfolder/"
string Targetpat =
"ftp://ftp.com/Mainfoder/DownloadedFiles/"+subfolder+"/"+todaydatefolder+"/"+susubfolder;
Uri serverFile = new Uri(sourceurl + filename);
request = (FtpWebRequest)FtpWebRequest.Create(serverFile);
request.Method = WebRequestMethods.Ftp.Rename;
request.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
request.RenameTo = Targetpat+"/"+newfilename;//folders without filename
response = (FtpWebResponse)request.GetResponse();
Stream ftpStream = response.GetResponseStream();
An unhandled exception of type 'System.Net.WebException' occurred in System.dll
Additional information: The remote server returned an error: (553) File name now allowed.
response = (FtpWebResponse)request.GetResponse(); //This line throwing the above exception
request.RenameTo = newfilename: when I set only newfilename, it renames that source same file name only.
How can I move this file to another directory within in same FTP server?
Please can anyone tell me. Thank you
As I wrote you already before:
request.RenameTo takes a path only.
So this is wrong:
string Targetpat =
"ftp://ftp.com/Mainfoder/DownloadedFiles/"+subfolder+"/"+todaydatefolder+"/"+susubfolder;
request.RenameTo = Targetpat+"/"+newfilename;
It should be:
string Targetpat =
"/Mainfoder/DownloadedFiles/"+subfolder+"/"+todaydatefolder+"/"+susubfolder;
request.RenameTo = Targetpat+"/"+newfilename;
I have an application that uploads a file. I need to pass this file into another program but for that I need the file name only. Is there any simple code for that, using only Java or a servlet procedure?
while (files.hasMoreElements())
{
name = (String)files.nextElement();
type = multipartRequest.getContentType(name);
filename = multipartRequest.getFilesystemName(name);
originalFilename = multipartRequest.getOriginalFileName(name);
//extract the file extension - this can be use to reject a
//undesired file extension
extension1 = filename.substring
(filename.length() - 4, filename.length());
extension2 = originalFilename.substring
(originalFilename.length() - 4, originalFilename.length());
//return a File object for the specified uploaded file
File currentFile = multipartRequest.getFile(name);
//InputStream inputStream = new BufferedInputStream
(new FileInputStream(currentFile));
if(currentFile == null) {
out.println("There is no file selected!");
return;
}
There's a method in apache commons-io to get the file's extension. There's also guava Files class, with its getFileExtension method.
