Hi Norbyte and thanks a lot for this amazing tool !

One question though:
Is it really necessary to disable V1 .lsx to binary compression (and vice versa) ?

Some might still want to use the tool for classic modding, because it's a necessity for more serious modding, and classic probably has tons more of old version files.

Tried to convert the current ItemCombosPreview.lsx to LSB and that threw an 'old version not supported exception'. Could do it with the old (pre-EE) tool (and with an older version of the current tool last year before the editor came out) though and could do it with the current one after manually copying two 'version lines' from a newser LSX to the file.
(which of course I could not do when decompressing: copying some bytes into the binary.)

EE probably still has a wild mix of old and new version files and maybe that is the reason why recently my attempts to unpack some book LSBs failed. And probably the reason why batch conversion failed until the 'offending' LSBs were removed from the directory.

It's only XML after all or is there some magic I haven't noticed yet ?
(like the 'chunk thing')
