#1465 Bug: 7z opens a file for read/WRITE access when just EXTRACTing ...

[Daniello Alto]

... so in case
you've
1. open myfile.7z in a hexeditor that opened the file with just shareRead and now
2. Like to Extract that file in 7Zip
7z will give Error:
'Can't access file since it's used by another process.'

I see that error unnecessary.
It can be avoided if 7zip only opens the file for write access if it really intent to perform any modifications
