Getting the folder name from a full filename path
I would probably use something like:
string path = "C:/folder1/folder2/file.txt";
string lastFolderName = Path.GetFileName( Path.GetDirectoryName( path ) );
The inner call to GetDirectoryName
will return the full path, while the outer call to GetFileName()
will return the last path component - which will be the folder name.
This approach works whether or not the path actually exists. This approach, does however, rely on the path initially ending in a filename. If it's unknown whether the path ends in a filename or folder name - then it requires that you check the actual path to see if a file/folder exists at the location first. In that case, Dan Dimitru's answer may be more appropriate.
Get folder name of the file in Python
You can use dirname
:
os.path.dirname(path)
Return the directory name of pathname path. This is the first element
of the pair returned by passing path to the function split().
And given the full path, then you can split normally to get the last portion of the path. For example, by using basename
:
os.path.basename(path)
Return the base name of pathname path. This is the second element of
the pair returned by passing path to the function split(). Note that
the result of this function is different from the Unix basename
program; where basename for '/foo/bar/' returns 'bar', the basename()
function returns an empty string ('').
All together:
>>> import os
>>> path=os.path.dirname("C:/folder1/folder2/filename.xml")
>>> path
'C:/folder1/folder2'
>>> os.path.basename(path)
'folder2'

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.IO;

WriteTree(info);
writer.WriteEndDocument();
writer.Flush();
writer.Close();
Console.WriteLine("Enter Return");
Console.ReadLine();
}

{
long size = 0;
writer.WriteStartElement("Folder");
try

writer.WriteAttributeString("date", info.LastWriteTime.ToString());
foreach (DirectoryInfo childInfo in info.GetDirectories())
{
size += WriteTree(childInfo);
}

catch (Exception ex)
{
string errorMsg = string.Format("Exception Folder : {0}, Error : {1}", info.FullName, ex.Message);
Console.WriteLine(errorMsg);

FileInfo[] fileInfo = null;
try

Extract only folder name right before filename from full path
This may solve:
filePath <- "/data/folder1/subfolder1/foo.dat"
basename(dirname(filePath))

How do I get the directory from a file's full path?
If you've definitely got an absolute path, use Path.GetDirectoryName(path)
.
If you might only get a relative name, use new FileInfo(path).Directory.FullName
.
Note that Path
and FileInfo
are both found in the namespace System.IO
.
How to extract directory path from file path?
dirname
and basename
are the tools you're looking for for extracting path components:
$ VAR='/home/pax/file.c'
$ DIR="$(dirname "${VAR}")" ; FILE="$(basename "${VAR}")"
$ echo "[${DIR}] [${FILE}]"
[/home/pax] [file.c]
They're not internal bash
commands but they are part of the POSIX standard - see dirname
and basename
. Hence, they're probably available on, or can be obtained for, most platforms that are capable of running bash
.
How do I get the file name from a String containing the Absolute file path?
just use File.getName()
File f = new File("C:\\Hello\\AnotherFolder\\The File Name.PDF");
System.out.println(f.getName());
using String methods:
File f = new File("C:\\Hello\\AnotherFolder\\The File Name.PDF");
System.out.println(f.getAbsolutePath().substring(f.getAbsolutePath().lastIndexOf("\\")+1));
How can I extract the folder path from file path in Python?
You were almost there with your use of the split
function. You just needed to join the strings, like follows.
>>> import os
>>> '\\'.join(existGDBPath.split('\\')[0:-1])
'T:\\Data\\DBDesign'
Although, I would recommend using the os.path.dirname
function to do this, you just need to pass the string, and it'll do the work for you. Since, you seem to be on windows, consider using the abspath
function too. An example:
>>> import os
>>> os.path.dirname(os.path.abspath(existGDBPath))
'T:\\Data\\DBDesign'
If you want both the file name and the directory path after being split, you can use the os.path.split
function which returns a tuple, as follows.
>>> import os
>>> os.path.split(os.path.abspath(existGDBPath))
('T:\\Data\\DBDesign', 'DBDesign_93_v141b.mdb')
