Hi,

I’m fairly new to ruby and am trying to use the rubyzip library (I  
downloaded the latest gem) to change a directory name in a zipped file.  
The code below seems to work (i.e. the directory names show as changed  
in winzip), but I get “crc errors” when I try to actually decompress  
the file. I’d really like to avoid the overhead of unzipping and  
re-zipping each file. Any suggestions would be greatly appreciated!

require ‘zip/zip’

target = “test.zip”

Zip::ZipFile.open(target) do |zipfile|  
zipfile.each do |e|  
if !e.directory? and e.to\_s.include? “olddir”  
zipfile.rename(e.to\_s, e.to\_s.gsub(“olddir”, “newdir”))  
end  
end  
end

- Dan

I’ve got exactly the same problem. I sent the information to the  
developers of rubyzip and they created a bug in the tracker.

Just in case, has someone found a solution of that ? Maybe an unknown  
patch ? 🙂  
Thanks in advance,
