Well you can always use edge to ignore a limit (like not having attack (if you have any left))
There is a chance that the file is protected but you will not know that before you mark the data server.
The actions are:
1. Mark.
2. browse the files to select what file to target.
3. If there is a data bomb disarm it (or take some nasty damage) (need firewall)
4. If there are protections crack the file (need attack)
5. Edit the file to copy it to your own device.
so whether or not you need an attack depends on the file, the information can indeed help you.
@Kynos You will get a reply after about 20-30 minutes. You guys need to decide if you are patient enough to wait, or you go into decontamination or leave. (of course your characters do not know that there will be an answer). The time that pass is how long it take before a human goes in and check on you. I'll leave that to you to decide.
