Binary package hint: file-roller
Winzip and many other zip programs can now produce zip files that are protected by 256 AES encryption. FIle-roller in ubuntu cannot handle these zips. The files within the zips are shown fine but when you try and extract the following error occurs:
skipping: Test.txt unsupported compression method 99
I believe this is because "unzip" is used to extract the archive. This is the output from "unzip":
dbrewer@HCC122J:~/Desktop$ unzip Test.zip
Archive: Test.zip
skipping: Test.txt unsupported compression method 99
If "7z" is used it works fine:
dbrewer@HCC122J:~/Desktop$ 7z x Test.zip
7-Zip 4.51 beta Copyright (c) 1999-2007 Igor Pavlov 2007-07-25
p7zip Version 4.51 (locale=en_GB.UTF-8,Utf16=on,HugeFiles=on,2 CPUs)
Processing archive: Test.zip
Extracting Test.txt
Enter password (will not be echoed) :
Everything is Ok
So I propose that file-roller uses "7z" instead of "unzip".
I attach an example of this kind of file. The password is "monkey" (no quotes).
Note peazip also can handle this. Maybe a replacement for file-roller? |
