Can read files in the compressed file directly?

I have a large number of compressed files (ZIP) stored in different directories. For some reason, I want to be able to read all the CSV files in the compressed files directly, but do not unzip it. Now, I can only read the file list in the compressed file. What should I do next?

dataList = FileNames["*.ZIP", "//Data//", 3];
data = Flatten[#, 1] &@Import[#, {"ZIP", "FileNames"}] & /@ dataList

Hi Tsai,

What do you mean by

The zip file has to be unzipped to access its contents. Maybe this is what you are looking for?

data = Import[#, "*.csv"]& /@ datalist

This should be able to import the files in a zip archive:

zipFile = "testzip.zip";
data = Map[
  Import[zipFile, {"ZIP", #}] &,
  Import[zipFile, {"ZIP", "FileNames"}]
];

You can use vim to list the content of the zip/rar/tar archive:

vim archive.zip

If you're having trouble reading in Chinese characters, I recommend fiddling about with the character encoding. I had a similar problem once that I solve by first setting:

$CharacterEncoding = "UTF8"

Give that a try before importing the files.
