File Managemant Utitlity is broken completly (NXT and EV3)
It realy can't do ANYTHING except deleting files and Renaming the Brick.
If you try to download something to your computer on the EV3 it says (as example) cannot get File Size for "FileName.Extension.Extension"
and on NXT something similar to this
cannot find file "FileName.Extension.Extension"
And one weird thing about the error messages is, that they Include the extension twice (test.txt.txt) is that the error maybe?
