Permission problems with deep directories

[eirslett]

If you make a 7z archive like this:

index.txt
a/b/c.txt

and try to extract it with the web worker, it doesn't work - you get a "permission denied" error. Is there something wrong with the filesystem?

Hi, erislett! Execuse me for a long responce. Have you tried your archive here?

https://blog.slava.online/archive/7z/ ?

I've tested. It seems to be ok.

I tried it on your link, this is what i get:

This is what I did to reproduce:

mkdir tmp
cd tmp
touch index.txt
mkdir -p a/b
touch a/b/c.txt
7z a archive.7z

I tried to upload the archive that was generated here: http://s000.tinyupload.com/download.php?file_id=07271242749141463279&t=0727124274914146327912992

Also, if I run the extract command with p7zip locally (not in the browser, but in the desktop terminal) it works fine.

Ok. Thanks. You are right. It is needed to create subfolders in the code.

I've got exactly the same issue: ERROR: Can not open output file : Permission denied : ... for a folder layout.

Is there any known way to work-around? :thinking:

4 years ago already, time flies!

I built my own library eventually: https://github.com/eirslett/shoeset does that one work for you?
