How to remove all files in a directory in java?

I have tried method delete() of File ,
but no effect!
can anyone help me!
thank you

So, you have a directory and you want to delete all files in the directory. Here is some (untested) code:
File dir = new File("C:\\tempdir");
File[] files = dir.listFiles();
for (int i = 0; i < files.length; ++i) {
if (files.isFile()) {
files[i].delete();

File Dialog - How to remove all files pattern in LV 8.x

How to remove "all files" pattern in LV 8.x in the file dialog.
Is it possible?
Thanks

If it is a security issue, you will probably need to implement a custom dialog and actively filter for file types. No matter what pattern you have showing, the user can type a pattern into the dialog and get anything they want. In addition, file extension is not sufficient to determine file type. You should probably check the file itself to ensure it is an HTML file and does not have any embedded nastiness.
Fortunately, custom dialogs are easy to make. Using the event structure, you can filter inputs as well, so that only HTML files will be accepted. Good luck. Let us know if you need more help.

How to get all files in one directory

Hi there,
is there any way to get all the files in one directory?
e.g. a method
File[] getAllFiles(String directory){
Thank you

Just out of interest, which part of the File API was confusing?
http://java.sun.com/j2se/1.5.0/docs/api/index.html
If you look down the left-hand side, you'll see a frame listing "All File". If you select "File" from that list, it opens up the API in the right-hand frame. Quite near the top you'll find "listFiles".
I only ask as this (and other questions easily answered by looking at the API) are frequently asked. Did you overlook it when you read the API or did you just not read it?
I really want to know. I think there is scope to cater for that behaviour within this site. A nice API finder would be good; something more intelligent than the search function (which people use less frequently even than the API docs).

How can I create a array with all files from a directory

How can I create a array of files or varchar with all files from a directory?

I thought the example could be improved upon. I've posted a solution on my blog that doesn't require writing the directory list to a table. It simply returns it as a nested table of files as a SQL datatype. You can find it here:

How to get the file size (in bytes) for all files in a directory?

How to get the file size (in bytes) for all files in a directory?
The following code does not work. isFile() does NOT recognize files as files but only as directories. Why?
Furthermore the size is not retrieved correctly.
How do I have to code it otherwise? Is there a way of not converting f-to-string-to-File again but iterate over all file objects instead?
Thank you
Peter
java.io.File f = new java.io.File("D:/todo/");
files = f.list();
for (int i = 0; i < files.length; i++) {
System.out.println("fn=" + files);

     System.out.println("file[" + i + "]=" + files[i] + " size=" + (new File(files[i])).length() ); }

How to read all files under a folder directory in FTP site

Hi Experts,
I use this SQL to read data from a file in FTP site. utl_file.fopen('ORALOAD', file_name,'r');
But this need to fixed file name in a directory. However, client generate output file with auto finename.
SO do we have any way to read all file by utl_file.fopen('ORALOAD', file_name,'r');
We need to read all file info. because client claim for security issue and does not to overwirte output file name,
we must find a way to read all file in output directory.
Thanks for help!!!
Jim

If you use Chris Poole's XUTL_FTL package, I believe that contains functions that allows you to query the directory contents.

How to remove bad file?

hi
I am creating external table to import csv file into table...I put csv file in this directory(c:\temp1\hr.csv)...while importing, the bad file and text document are created..Actually the client does not require this....Can anyone say how to remove those files while importing?
Fazila

First of all bad file contains those record information which is rejected for any specific reason. So, you can get some valuable information regarding the rejected records. But, still if you don't want to keep it - then you can do it with a java based procedure. I don't thinki you can do it directly through any oracle procedure. Because, you are about to access the o/s system files. I don't think that can be done directly using Oracle Pl/SQL - which i'm not sure.

How to create pdf files in UNIX directory from oracle reports

I would like to know how to create pdf files in UNIX directory from oracle reports.
Thanks,

Please make your question more clear . Also mention the reports version.
1) If you are runnning reports in Unix, you can give
.... destype=file desformat=pdf desname=<filename>
in command line
Please refer docs below.
2) If by your question you mean
"My reports server is running in Windows but I want to ftp my files to Unix after creating it"
then the answer is that you can use pluggable destination "ftp"
.... destype=ftp desformat=pdf desname=<ftp url>

How to delete all files and folders (with files) in IsolatedStorage.

Hi awesome programmer:-) The code I have to clean up the local folder doesn't work properly so I won't even bother posting it here. I basically want to have a "master reset" option to remove all new created files and folder in the local folder.
Can you give me simple code to remove all files/folder so the app goes back to the state it was when the user installed it for the first time? Thanks in advance. ps I were able to delete a directory(-ies) with this method:
private async void DeleteDirectory(string directoryName)
try
var folder = await Windows.Storage.ApplicationData.Current.LocalFolder.GetFolderAsync(directoryName);
if (folder != null)
await folder.DeleteAsync();
this.Dispatcher.BeginInvoke(delegate()
txtUpdateFeed.Text = "Folder < " + directoryName + " > deleted.";
catch (Exception ex)
this.Dispatcher.BeginInvoke(delegate()
txtUpdateFeed.Text = "Delete Directory << " + directoryName + " >> Error: " + ex.GetBaseException().Message.ToString();
It seems to work, I have not tested with all conditions though. Anyway let me put up the code so you can see I have been trying: This is to delete everything but not all files are deleted:
private void WipeAllData(bool bln)
try
txtUpdateFeed.Text = "Removing files...";
if (bln)
txtUpdateFeed.Text = "Removing folders...";
//Delete videos directory
DeleteDirectory("videos");
//Delete pictures directory
DeleteDirectory("pictures");
txtUpdateFeed.Text = "Folders removed.";
//Delete the rest of the files
var iso = IsolatedStorageFile.GetUserStoreForApplication();
foreach (string name in iso.GetFileNames())
iso.DeleteFile(name);
BtnWipeAllData.Content = "Wipe All Data";
VideoCameraPowerValue = "on";
BtnVideoCameraPower.Content = "Video Camera: ON";
PhotoCameraPowerValue = "on";
BtnPhotoCameraPower.Content = "Photo Camera: ON";
txtUpdateFeed.Text = "Files removed successfully.";
catch (Exception ex)
MessageBox.Show("Wipe All Data Error:\n" + ex.Message.ToString());
Why isn't all files being deleted?

Hi Clint William Theron,
Based on your descriptions, I know that when you run the above code, it does not delete all the files, then have you checked that which kinds of files or in which folder the files can not been deleted?
Besides, if you want to let the app go back to the state it was when the user installed it for the first time, then an easy way is to uninstall and reinstall it.

How to Zip server files(in a directory) and throwing back to client

Can someone tell me how to zip all the files in a particular directory of my web application and throwing back to client to give option for save that zipped file.
i have used the below used function to zip in servlet. But I cann't zip a particular directory of my application in server.
Please help

try
//create a new File object based on the directory we
// have to zip File
File fileDir2Zip = new File(dir2zip);

Hi
Whatever file exist in directory should execute with out any condition because they delete all files after exection of my process chain. They are using another process chain once a day for deletion of all files in that directory.
So directory always contains fresh files.
Here by using routine in infopackge i am unable to run all files one by one at a time.
As of my knowledge by using infopackage we can run only one file at a time.
Here my question is , can we run more than one file in single run of infopackage?
or can we have any function module to run the infopackage from externally? so that i can use function module in abap program? any ideas..

Raju

How to duplicate a file in a directory to another directory?

I am a student just has just learn some basic Java programming...May i know how to duplicate a file in a directory to another directory?
How to start in doing this?
Thank You

I was suggesting to use java to send commands to the system shell so to speak....
I don't know of a way to do this... under the File class you can delete files, but there is no provision to copy Files so to speak....
one way would to be to open the file you want to copy with a file reader, and then write it all out to your new file.
see http://java.sun.com/j2se/1.3/docs/api/java/io/FileReader.html for information of FileReaders

How to remove all transitions?

I used the automate to sequence with default transition. A few dozens of transitions were added to the sequence.
How to remove all the transitions without deleting the sequence and starting from scratch please?
Thanks in advance.

The difference in file size you are seeing is because you are only using motionless stills in your movies. No motion, and no effects. Some codecs allows for file size reduction by writing first and last frame information for a still, regardless of the length in the video sequence. Why the transition increases file size is because the codec actually has to write info for each frame in the length of the transition.
This is not going to be the case with anybody working with actual video clips, or if someone adds motion to their stills. The codec then has to write information for every frame, resulting in a larger file size. For most projects, transitions will not make any significant change in file size.

How to remove all hyperlinks at once?

Hi guys,
I want to know how to remove all hyperlinks in a text at once. I know how to remove one link at a time. But it's time consuming if you paste a text with a lot of hyperlinks.
Thanks,

Enregistrer le script en tant qu'Application ou Progiciel : remove links.app
Déposez le sur le bureau par exemple.
Glisser-déposer l'icône d'un document Pages sur celle du script
va éliminer tous les Hyperliens et signets prédsents dans le document.
On peut également qlisser déposer un fichier index.xml.
+++++++
Save the script as an Application or an Application Bundle: remove links.app
Store it on the desktop for instance.
Drag and drop the icon of a Pages document on the script's icon
to remove the Hyperlinks and Bookmarks embedded in the document.
We may also drag & drop an index.xml file.
