From what I can read here ("How SDelete works"), shredding the files properly can be a bit tricky, when it comes to compressed, encrypted or sparse files. And it seems even more complicated when you try to implement the same for free space...

I don't think there is any dependency to the filetype - the physical file is overwritten with some pattern, maybe multiple, and that's it.

Free space is another thing...

Statler wasn't talking about filetype, but the storage attributes on an NTFS file. There are some issues beyond simply using the standard basic file I/O routines to overwrite the files.

You should follow the link (which may not have been obvious - http://technet.microsoft.com/en-us/sysi ... 97443.aspx) for the details.

Sorry, that's right - I misinterpreted meaning of 'compressed' as of something like zipped...

Indeed interesting, thanks for pointing to it.

I assume SDelete supports command line switches, so it would be easy to integrate it into XY via a user command?

Yes. it does. The switches are documented on the same page.

Oh, I must have been switch blind. Too much beach time...

It appears that my dotage has left me "syntax challenged".

Would some provide an example of how to use Sdelete from the Catalog on a group of selected files.

Thank you ...

Haven't tried it, but it seems if you choose "Open selected List Item(s) with Application" under "Action on click" (in the Advanced section at the bottom) and put the path to sdelete.exe into "Application", it should work.
Not sure if it allows multiple items to be deleted at once, if not simply choose "Multiple Instance" and that should do it.

Thanks oh wise one. That bit about multiple instances was the key to success. A matter of not seeing the forest through the trees really.

I use this:

Yes - that's it! It was the use of the double "double quotes" that was throwing the script syntax off this morning.

Actually I'm not so happy with the double "double quotes" rule as it is right now (in UDC and Scripting). I wished I opted for the common standard!!

XYplorer: use double quotes around app when there are command switches.
Common standard: use double quotes around app when app path contains blanks.

I know I cannot go back now because it would break tons of user code. But maybe I could offer an option (tweak) to use the common standard? Opinions?

Yes, make it optional please. +1 for this.
