Is it possible to copy a folder to a non empty destination without deleting the contents of the destination folder first?
My current implementation is as follows
var folderObject = NSFileManager.defaultManager();
folderObject.removeItemAtPath_error(toPath, nil);
folderObject.copyItemAtPath_toPath_error(fromPath, toPath, nil));
What i need to achieve is overwrite the contents of destination folder with that of source folder.
The call removeItemAtPath_error deletes the destination directory and copyItemAtPath_toPath_error creates a directory of the same name as the deleted one, hence it is empty.
As a side note, the naming of your NSFileManager instance is somewhat misleading, as it is not a folder object but a file manager instance reference.
An example of how this can be done (I'm unfamiliar with PyObjC, so this is only for inspiration):
# Define paths
var sourcePath = "/my/source/path/"
var targetPath = "/my/target/path/"
# Create reference to file manager
var fileManager = NSFileManager.defaultManager();
# Create array of all file and directory paths inside the source directory
var sourcePaths = fileManager.contentsOfDirectoryAtPath_sourcePath_error(sourcePath, nil);
# For each source file or directory
for sourcePath in sourcePaths:
# Copy the file or directory to the target path
fileManager.copyItemAtPath_toPath_error(sourcePath, targetPath, nil);
I am assuming that this recursively copies the directories from the source and maintains the directory tree.

I'm using Grails 2.5.6 to store uploaded images to folder on a server.
The following are my code to store the image
mpr.multiFileMap.file.each{fileData->
CommonsMultipartFile file = fileData
File convFile = new File(file.getOriginalFilename());
file.transferTo(convFile);
/** Processing File **/
File uploadedFile = new File("${directory}${generatedFileName}.${extension}")
convFile.renameTo(uploadedFile)
}
I have no problem running on development (MacOSX High Sierra)
But when i deployed on production (Ubuntu 14.04 server), i could not save the file outside CATALINA_HOME directory.
I have checked the permission and ownership of the destination directory, but still, the directory was created but the file was never stored.
For Example, i've tried to store the file on /home/tomcat/ directory (/home directory was in separate partition with tomcat which stored it /var), the directory was created, but the file was never stored.
When i put the destination directory within CATALINA_HOME folder, everything works fine. But this was not the scenario i want to do.
You say your destination directory is on another partition, so maybe another filesystem is used on this partition.
Or if you look on the javadoc of the renameTo method it is said :
Many aspects of the behavior of this method are inherently
platform-dependent: The rename operation might not be able to move a
file from one filesystem to another, it might not be atomic, and it
might not succeed if a file with the destination abstract pathname
already exists. The return value should always be checked to make
sure that the rename operation was successful.
...
#return true if and only if the renaming succeeded;
false otherwise
Thus I think the renameTo method is not able to move the file, don't know why but you can rewrite your code like this :
mpr.multiFileMap.file.each{fileData->
CommonsMultipartFile file = fileData
File uploadedFile = new File("${directory}${generatedFileName}.${extension}")
// String originalFilename = file.getOriginalFilename()
// you can store originalFilename in database for example
if(!uploadedFile.getParentFile().exists()) {
uploadedFile.getParentFile().mkdirs()
// You can set permissions on the target directory if you desired, using PosixFilePermission
}
file.transferTo(uploadedFile)
}
This seems to be a problem which is very difficult to explain. I am trying to read data from a folder full of files and the way I am trying to do this is by scanning the whole directory for all of the files. The file in question is stored in my Xcode project in the same directory as the view controllers and storyboards. Like so:
I would like to be able to scan the contents of the "data" folder. Consider the following code:
var tmpDir = NSTemporaryDirectory()
var error: NSError?
let filesInDirectory: [String]! = fileManager.contentsOfDirectoryAtPath(tmpDir, error: &error) as? [String]
This scans the contents of the app's local folder and returns it as an array of the file names. I would like to be able to do this with the "data" folder in my Xcode project. The following code will find the contents of a single file which is stored in the same directory as the "data" folder.
let files = NSBundle.mainBundle().pathForResource("sampleFile", ofType: "csv")
var contents = String(contentsOfFile: path!, encoding: NSUTF8StringEncoding, error: nil)!
Is there a way in which I can combine the capabilities of the two in order to scan the contents of the "data" folder in the Xcode project and then return the file names as an array?
Add the data folder to Copy Bundle Resources in Build Phases of your target.
Then you'll be able to read the path as it's within the same sandbox scope. (Assuming you are applying sandbox.) If not, just use absolute path/URL and you can access it directly without the copying process.

How can I update the following code to save in a directory of my choice on IIS. Currently it will only save in my downloads directory with the file name of the path.
E.g.. the following example saves in my downloads directory as
C--inetpub-wwwroot-sitename-Feeds-reports.xml
[HttpGet]
public XmlActionResult GetXmlData()
{
System.Xml.XmlTextReader reader = new System.Xml.XmlTextReader(Server.MapPath("~/reports.xml"));
var xml = XElement.Load(reader);
//I want to save the file to the following destination but this saves it with the file name of the destination in my downloads directory
return new XmlActionResult(xml.ToString(), Server.MapPath("~/Feeds/reports.xml"));
}
EDIT
I want to move the reports.xml file from the current directory to the Feeds directory.
I want to read file from "res" folder on blackberry. The file that i used is a file javascript.
I used this code InputStream in = classs.getResourceAsStream("file.js");. But i get "could not find this path" and I use also
String srcFile = "/res/ressourcesWeb/file.js";
FileConnection srcConn = (FileConnection) Connector.open(srcFile, Connector.READ);
InputStream in = srcConn.openInputStream();
but i got an exception.
Can any one help me to read the file and give me the right path that should I use?
Your res folder has to be inside src folder to be accessed from your code.
src folder is the root folder of your project package. And all folders outside of src folder are invisible for the code at runtime.
Check this post for more details: Blackberry runtime error: FRIDG: could not find img/logo.png
There's file location principle described.
You actually do not need to put your resources under the src folder for them to be accessible from your code.
That is one way to do it, but I don't think it's the best way. Files under the src folder should really be source code, not images, or other resources. For JavaScript resources, it's debatable whether those should be under src or not. Most projects I've seen have used the src folder for only Java source code.
In any case, if you would like to keep your file (or other resources, like images) outside the src folder, you can do so. The BlackBerry plugin for Eclipse actually sets it up like this by default, when you create a new project. There is a res folder at the top level, next to (not under) src.
If you have
src\
src\com\mycompany\myapp\
res\
res\resourcesWeb\
res\resourcesWeb\file.js
Then, you can open the file like this:
String jsPath = "/resourcesWeb/file.js";
InputStream input = getClass().getResourceAsStream(jsPath);
byte [] content = IOUtilities.streamToBytes(input);
String contentAsString = new String(content);
P.S. You also can probably do this:
String jsPath = "/file.js";
InputStream input = getClass().getResourceAsStream(jsPath);
and not specify the path to the resource. Obviously, this will only work if there are no naming conflicts in your resource folders (e.g. you don't have /res/resourcesWeb/file.js and also /res/otherPath/file.js)
I want to have one directory for all object files and create Common.pri file that set OBJECTS_DIR like that
OBJECTS_DIR = $$PWD/../
But when build project i can't find obj file in given directory.If I write this direct in .pro file I get the expected result.I successfully include Common.pri file. I checked that with
!include( ../../Common.pri)::warning(Fail to include Common.pri)
How to achieve what i want.I can't find anything in google
The PWD variable specifies the full path leading to the directory containing the current file being parsed, that is, in your case the full path leading to the Common.pri file and NOT the .pro file. I would place a warning($$OBJECTS_DIR) function in both the .pri and the .pro file to verify the value of OBJECTS_DIR variable.
