hello
I become to use tar with incremental feature for archiving data under ubuntu.
But when I try to extract archive later under windows (using gnu tar also) it creates many directories like this:

<...>
11324447220
11324447221
11324447223
11324447247
11324447275
11324447331
11324447343
11324447344
11324447345
<...>
home
etc

Internal structure of each of those directories is similar to main archived structure (subdiectories home and etc).
Some files are archived in those subdirectories
(for example: 11324447345/home/user1/document.txt) and some on main level (as they expected). I can't find any rule for it.
Under linux everything seems to be ok.

What is the problem? It's a matter of some tar switch or bug?

Windows might not have UTF-8 encoding. You might be able to add it. Or, you can use 7-zip, which exists for both Linux and Windows.

Ok, I found that this is tar for windows bug announced in 2008-10 and still waiting for resolving.
