Hello,
someone can help me to export skills from DAIL mod? (like GrimCalc)
Bye 
Are you wanting to get inside the DAIL.arz?
If so, make a new folder and copy archivetool.exe, zlibwapi.dll(both found in main GD directory) and Dail.arz into it.
Run CMD, change directory to your new folder.
Type: archivetool Dail.arz -database new folders full directory\another new folder
Example: archivetool Dail.arz -database d:\gdmodarchive\1

Thank you for your reply.
Maybe with my bad English I have not been able to explain exactly what I’m looking for.
I’d like to extract only the description of all skills in the DAIL mod.
It would be fantastic if I could get a result similar like GrimCalc.com but I’m a dreamer 
Following your instructions I extract a lot of folders and files but if I try to open a file that is in folder “Skills” or similar I can read only the scaling of skill and not the full description of that.
Probably I can not find the exactly files or folder that contains what I’m looking for.
The file that shows the skill name and description is tags_skills.txt found in resources/ui/TEXT_en/
However to get all the parameters of the skill, I’m not sure of another way other than reading through those dbr files, you can open them with notepad++ or something similar, might make for easier reading.
Someone else have a better idea
edit: to read .arc files use the same method but replace -database with -extract.
