How to zero size all files in a folder

How to zero size all files in a specific folder. And then continuing on, how do I zero any new files placed in that folder in the future.

Yes. But I need to retain the domain name. So if your depiction is meant to represent the original domain names. This is correct.

But after this has been completed. There will be other files added which won't have zero file sizes. And I'd like some method of zeroing the size of those files too.

What is your purpose for doing this?

There's no problem with 0-sized files on any filesystem I know of. Powershell can easily do this.

Code:

PS C:\temp\zero> dir

    Directory: C:\temp\zero

Mode                LastWriteTime         Length Name
----                -------------         ------ ----

PS C:\temp\zero> dir | New-Item -Force -Value ""

    Directory: C:\temp\zero

Mode                LastWriteTime         Length Name
----                -------------         ------ ----

@bro67 - Sorry. I was tired when I sent my last reply. I'm sorry about that. Domain Name should be File Name. But I'm confused about what you say about the MBR and file table.

@margrove55 - The purpose is I'm continually receiving new files into this folder, and when after I have processed them, I want to convert the original files in the folder to zero bytes, so that I cannot receive the same files twice and process them twice.

@PolarNettles - What is Powershell? Does this come as part of Win10? I know I'm showing my noobness. If not. Where to get it. Is this the exact command I need to run or are these parameters only? And if so, What is the exact command line required to achieve this effect.

And then to the second part of my question? How to zero-ize only the filenames which have file sizes, the next I time run the command. Is that even possible?

Powershell is built in to Win 10. You can write PowerShell scripts similar to batch files. There are tutorials and courses available online, such as Getting Started with PowerShell 3.0 Channel 9 .

You can write the PS script to only zero out files with size > 0. This would be a good exercise as you are learning it.

You do not want to set file size to 0. It will mess up the MBR and File Tables. There is zero reason to even do what you are doing.

Please provide proof. Zero-sized files are used all the time . And why would the "file table" affect the MBR?

PS D:\> dir
