Is it possible to unzip all files from the zip folder without its folder?
Example:
zipfolder.zip has two subfolders called folder1(having files like 1.txt, 2.xlsx, 3.pdf) and folder2(having files like 4.txt, 5.pdf)
Note: The source can any type of archive files like .zip, .rar, .tar, .7-zip etc
This is my code:
String sevenZipLocation = "C:\\Program Files\\7-Zip\\7z.exe";
String src = source filepath (zip file)
String target = output path (output path)
String[] command={sevenZipLocation,"x",src,"-o"+target,"-aou","-y"};
ProcessBuilder p = new ProcessBuilder( command );
Process process = p.start();
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
#SuppressWarnings("unused")
String line;
while ((line = br.readLine()) != null){
System.out.println("line1 "+line);
}
process.waitFor();
When I execute this code the output like
unzip folder ----- folder1(having files like 1.txt, 2.xlsx, 3.pdf) and folder2(having files like 4.txt, 5.pdf)
But I want to extract the only file from all folders and the output like
1.txt, 2.xlsx, 3.pdf, 4.txt, 5.pdf in the output path.
Is there any command for that. Thanks.
All you need to change:
String[] command={sevenZipLocation,"e",src,"-o"+target,"-aou","-y","*.*","-r"};
PS. I don't think Java is the best choice to run OS commands. You'll be wasting a lot of time. But if you insist, don't forget there might be an errorstream too.

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.
Is there a way to get a gzip archive file to unzip to a different destination when a user double clicks on the archive? Currently, my compression code looks something like this in Scala:
val filename = SetFilename.getOrElse {
val path = files.head.getAbsolutePath
val baseUrl = FilenameUtils.getFullPathNoEndSeparator(path)
...
}
val output = new File(filename)
val fos = new FileOutputStream(output)
val gzos = new GZIPOutputStream(new BufferedOutputStream(fos))
try {
files.foreach { input =>
val fis = new FileInputStream(input)
try {
ioStream(fis, gzos)
gzos.flush()
}
finally {
fis.close()
}
}
}
finally {
gzos.close()
fos.close()
}
IS there any way to tell the compressed files to decompress in a different destination when a user double clicks on the archive?
It is not the gzip archive that decides it will be unzipped in the same location, it's something the operating system you're unzipping it on decides.
If you need to unzip into a specific place, you should look for a packaging solution like deb for Ubuntu or Debian systems; or dmg for OSX.
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)
i 'm .net developer. i want to Zip all files and make a one zip file with this technique.
ZipFile multipleFilesAsZipFile = new ZipFile();
Response.AddHeader("Content-Disposition", "attachment; filename=" + DateTime.Now.ToString("ddMMyyyy_HHmmss") + ".zip");
Response.ContentType = "application/zip";
for (int i = 0; i < filename.Length; i++)
{
string filePath = Server.MapPath("~/PostFiles/" + filename[i]);
multipleFilesAsZipFile.AddFile(filePath, string.Empty);
}
multipleFilesAsZipFile.Save(Response.OutputStream);
how ever for making this Zip i use third party library Ionic.
all files are ziped successfully but not extracted to client desktop. is there problem with my code. or this library that i'm using has been expired.
Is there free full version .net compatible library to zip all files.
Use SharpZipLib:
Nuget Package
Install-Package SharpZipLib
OR Download here
http://www.icsharpcode.net/OpenSource/SharpZipLib/
Snippet from examples:
private void CompressFolder(string path, ZipOutputStream zipStream, int folderOffset) {
string[] files = Directory.GetFiles(path);
foreach (string filename in files) {
FileInfo fi = new FileInfo(filename);
string entryName = filename.Substring(folderOffset); // Makes the name in zip based on the folder
entryName = ZipEntry.CleanName(entryName); // Removes drive from name and fixes slash direction
ZipEntry newEntry = new ZipEntry(entryName);
newEntry.DateTime = fi.LastWriteTime; // Note the zip format stores 2 second granularity
// Specifying the AESKeySize triggers AES encryption. Allowable values are 0 (off), 128 or 256.
// A password on the ZipOutputStream is required if using AES.
// newEntry.AESKeySize = 256;
// To permit the zip to be unpacked by built-in extractor in WinXP and Server2003, WinZip 8, Java, and other older code,
// you need to do one of the following: Specify UseZip64.Off, or set the Size.
// If the file may be bigger than 4GB, or you do not need WinXP built-in compatibility, you do not need either,
// but the zip will be in Zip64 format which not all utilities can understand.
// zipStream.UseZip64 = UseZip64.Off;
newEntry.Size = fi.Length;
zipStream.PutNextEntry(newEntry);
// Zip the file in buffered chunks
// the "using" will close the stream even if an exception occurs
byte[ ] buffer = new byte[4096];
using (FileStream streamReader = File.OpenRead(filename)) {
StreamUtils.Copy(streamReader, zipStream, buffer);
}
zipStream.CloseEntry();
}
string[ ] folders = Directory.GetDirectories(path);
foreach (string folder in folders) {
CompressFolder(folder, zipStream, folderOffset);
}
}

Works awesome!
I'm developing an eclipse plug-in and I need to traverse a directory and whole content of the directory. I found the method which reads a file in plug-in (bundleresource) as InputStream.
InputStream stream = Activator.class.getResourceAsStream("/dir1/dir2/file.ext");
this method works for files only. I need a way to read directories, list subdirectories and files like File.io.
Thanks.
Do you want to read a resource directory of your plugin? Otherwise you have to traverse a directory and open one stream per file:
String path = "c:\\temp\\";
File directory = new File(path);
if (directory.isDirectory()) {
String[] list = directory.list();
for (String entry : list) {
String absolutePath = path + entry;
System.out.println("processing " + absolutePath);
File file = new File(absolutePath);
if (file.isFile()) {
FileInputStream stream = new FileInputStream(file);
// use stream
stream.close();
}
}
}
If you want to traverse subdirectories as well you should wrap this into a recursive method, check if file is a directory and call the recursive method in this case.
