It seems that Windows 10 is copying hidden system files to my SD card. After formatting my card in my 50g, there are no system files on it, but when I copy the files from the computer, Windows copies the hidden files over in a directory . I am able to delete the files in the directory, but not the directory.
When I try to execute < 3:SYSTEM~1 Purge > nothing happens. Is there a way to get this off of my card? I am able to delete the directory’s contents (I believe), so I am not trying to delete a non empty directory.
Thank you,

The bad news: Neither the HP 50g's Filer (left-shift APPS) nor the PURGE
command, even when used with DOS path notation (e.g. :3:"SYSTEM~1" PURGE),
can purge DOS directories from an SD card. You have to do that with a
computer. Sorry!
The good news: It doesn't matter. Just leave the directory there. It
won't have any bad effect on the HP 50g's operation.
Disclaimer: If I'm wrong, I'd be delighted to be corrected and thereby learn
something new. But I tried every way I could think of, and nothing worked,
so I currently suspect that it can't be done. Anybody know of a 3rd-party
library for the HP 50g that offers the desired functionality?

Well...I was expecting that, but Windows 10 won’t let me delete system folders. At least, I cannot figure out how. I tried that first.

If you've written files to the SD that you need on the calc then I
suggest safely ejecting (to make sure they are saved to the card) then
re-inserting the card and doing the above to remove the SVI folder.

I think that the directory can be removed with SDfiler utility that is
available from hpcalc org website. I recall that this utilily does not
respect the write protect tab, so be warned!

Thank you,
I’ll have to check the documentation. I’ve had that installed, if it’s Wolfgang Rautenberg‘s.

I do see it’s a different program. After installing it, it doesn’t see the system folder. I need to play with it. The documentation shows commands that aren’t showing, so maybe they need to be entered manually in the command line?

OK. The commands are executed like any other CAT command. SDFiler doesn’t see the directory and errs when SDRMDIR is executed.

The question here really is: Why is Windows 10 adding that hidden files/folder system? I think we should be looking specifically at that and not so much at the HP50G side. Under Windows 7, I have never seen the Win 7 adding hidden folder/files to my SD cards.

I couldn’t agree more. It’s irritating. It never did this on earlier versions. I use a Mac mostly and it puts system files on external Windows based media, so I would boot up a Windows machine just to avoid that.

For what it's worth, the SDRMDIR command will delete Windows system/hidden directories, just not THAT system directory. Seems the "System Volume Information" directory is a special case. Instead of the "File not found" error message, you get a "File in use" error message. So SDRMDIR must be able to see the directory, but not delete it.

I wouldn’t doubt that. SDFiler does not show the SVI folder in its directory listing, so I’m not surprised it cannot delete it.

Interestingly, SDRMDIR can delete other hidden/system directories that SDFiler does not show. The built-in Filer does show these hidden/system directories (as does the Filer6 program).

Yes, and the native filer can delete the system folder contents, but not the folder.

It's probably in use whenever the volume is mounted. Catch-22! Unless the command will work on unmounted volumes.
