Removing path and extension from filename in PowerShell

Question

I have a series of strings which are full paths to files   I d like to save just the filename  without the file extension and the leading path   So from this  c  temp myfile txt  to myfile  I m not actually iterating through a directory  in which case something like PowerShell s basename property could be used  but rather I m dealing with strings alone

This can be done by splitting the string a couple of times    Path  Link    http   some url some path file name    Split path on      Results of split will look like this      http      some url   some   path   file name  Split    Link Split        Count how many Split strings there are  There are 6 strings that have been split in my example  SplitCount    Split Count   Select the last string  Result of this selection      file name  FilenameWithExtension    Split  SplitCount -1    Split filename on      Result of this split      file   name  FilenameWithExtensionSplit    FilenameWithExtension Split        Select the first half  Result of this selection      file  FilenameWithoutExtension    FilenameWithExtensionSplit 0    The filename without extension is in this variable now   file  FilenameWithoutExtension   Here is the code without comments      Link    http   some url some path file name   Split    Link Split       SplitCount    Split Count  FilenameWithExtension    Split  SplitCount -1   FilenameWithExtensionSplit    FilenameWithExtension Split       FilenameWithoutExtension    FilenameWithExtensionSplit 0   FilenameWithoutExtension

Expanding on Ren   Nyffenegger s answer  for those who do not have access to PowerShell version 6 x  we use Split Path  which doesn t test for file existence   Split-Path  C  Folder SubFolder myfile txt  -Leaf   This returns  myfile txt   If we know that the file name doesn t have periods in it  we can split the string and take the first part    Split-Path  C  Folder SubFolder myfile txt  -Leaf  Split        Select -First 1   or    Split-Path  C  Folder SubFolder myfile txt  -Leaf  Split      0    This returns  myfile   If the file name might include periods  to be safe  we could use the following    FileName   Split-Path  C  Folder SubFolder myfile txt config txt  -Leaf  Extension    FileName Split        Select -Last 1  FileNameWoExt    FileName Substring 0   FileName Length -  Extension Length - 1    This returns  myfile txt config   Here I prefer to use Substring   instead of Replace   because the extension preceded by a period could also be part of the name  as in my example  By using Substring we return the filename without the extension as requested

Given any arbitrary path string  various static methods on the System IO Path object give the following results    strTestPath                   C  Users DAG Documents Articles 2018 NTFS File Times in CMD PathStringInfo ps1 GetDirectoryName              C  Users DAG Documents Articles 2018 NTFS File Times in CMD GetFileName                   PathStringInfo ps1 GetExtension                   ps1 GetFileNameWithoutExtension   PathStringInfo   Following is the code that generated the above output    console   Writeline   strTestPath                    0  1                            strTestPath    Environment   NewLine     console   Writeline   GetDirectoryName               0                            IO Path   GetDirectoryName   strTestPath       console   Writeline   GetFileName                    0                            IO Path   GetFileName   strTestPath       console   Writeline   GetExtension                   0                            IO Path   GetExtension   strTestPath       console   Writeline   GetFileNameWithoutExtension    0                            IO Path   GetFileNameWithoutExtension   strTestPath        Writing and testing the script that generated the above uncovered some quirks about how PowerShell differs from C   C  C    the Windows NT command scripting language  and just about everything else with which I have any experience
