You can use the following syntax in PowerShell to delete all files with no extension:
Get-ChildItem -File | Where { -not $_.extension } | Remove-Item
This particular example will delete all files in the current directory that have no file extension.
Here is what the various commands do:
- Get-ChildItem -File: Retrieves all files from current directory
- Where { -not $_.extension }: Filters for files with no extension
- Remove-Item: Deletes files with no extension
The following example shows how to use this syntax in practice.
Example: How to Delete Files with No Extension in PowerShell
Suppose that our current directory has the following path:
- c:\users\bobbi\data2
We can use Get-ChildItem -File to list all files in this current directory:
We can see that our current directory contains the following files:
- Three files with .txt extensions.
- Two files with .csv extensions.
- Two files with no extensions.
Suppose that we would like to delete the two files that have no extensions.
We can use the following syntax to do so:
Get-ChildItem -File | Where { -not $_.extension } | Remove-Item
The following screenshot shows how to use this syntax in practice:
Notice that when we run the Get-ChildItem cmdlet again to view the updated items in the directory we can see that each file without an extension has been deleted.
Note: You can find the complete documentation for the Remove -Item cmdlet in PowerShell here.
