Hi im lala here would like to ask something, if any investigator doing a computer forensic using free software tools, is it acceptable to use the evidence found in the court room ?  

In which country?
I am italian I use mainly open source software except mobile edit forensic and nobody said something  

Thank you for responding ????. I would like to know in any of your country so we can gather all information in one forum . So that i can make an analysis from all the answer receive ☺  

If the results of your forensic examination can be repeatable and validated, I do not see why using open source and free tools would be an issue. You will have additional explaining to do in court if it is a tool that is unknown and/or untested in the forensic community.

Personally, I would validate the opensource/free tool prior to using it in any case.  

I regularly use Open Source tools - as with any tool, so long as you know what it is doing, and can verify it, you're on solid ground. I would actually argue that this is _easier_ with open source, rather than proprietary software.

What I will say, is I would much rather work with a report created by someone who knows what they are doing using open source tools than a report generated by a "button clicker" in a commercial tool.
