load script into memory / avoid handle

[yasuo]

Hi there,

i have a script wich runs from USB, sometimes i will remove the USB after the script is startet, actually i even want to remove it using the script itself.

But windows will refuse ejecting the USB since the script is running from it and there is an open handle.

 

The common "resolution" is to copy the script to $temp and re-run it from there, but i dont want to copy my script for security reasons and i dont like filling up $temp.

 

Is there another way to end the script's handle or even to preload it completely into memory?

 

greetings

Don't know, but what about running it from temp and selfdelete on exit?

Agreed - have it delete itself on exit. A second way is simply have it run on a server. A third way if security is an issue is have an ID and password to launch the app.

What about creating a batch that eject the USB?

[Bert]

batch? that is so DOS....

[yasuo]

thanks for your ideas, but its not yet the solution

 

the batch is not the problem (you can use removedrive.exe or maybe devcon.exe), but as long the program runs from the same drive you cannot safely eject.

I also would avoid ejecting forcefully too often.

 

hmm deleting is an idea but "delete on exit" will not work in case the machine stops unexpected etc. etc.

deleting while its running is not possible normally

 

can i end the handle without stopping the program?

Perhaps if you could outline these security concerns, you might inspire a solution.

Not wanting to copy a file to a drive, but rather execute it in memory seems a little odd regarding security.
