Required software

• Python 3
• 7zip

Usage

1. Install required software

   Ubuntu : $ sudo apt-get install -y python3 p7zip*
   Windows : download and install 7zip and Python

2. Download here

   via command line

   Ubuntu : $ wget https://raw.githubusercontent.com/Wireless4024/Py7zRecompress/master/py7zRecompress.py
   Windows : > curl -o py7zRecompress.py https://raw.githubusercontent.com/Wireless4024/Py7zRecompress/master/py7zRecompress.py

3. Run! $ python py7zRecompress.py <Folder> [Folders...] [-wt work_thread] [-ct compress_thread] [-d deep_count] [-s extension_sensitive] [-dc dictionary_size] [-7z 7zExecutable]

   Folder path ... : Folder that contains compress-able files [7z, xz, zip, jar, rar, gz]
-wt int : Working thread count (default : 1)
   -ct int : Thread count used by 7zip (default : 3)
   -d int : How deep to re-compress (useful when you have zip inside zip again and again) (default : 2)
   -s yes|no : use compress algorithm same with file extension (default : no)
   -dc int : size of dictionary in MegaBytes used by 7z and xz (default : 96)
   -7z path : path to 7z executable (default : "7z.exe|7z")
   -e file_extension;... : excluded file extension eg. -e 7z;rar will not re-compress .7z and .rar file
   -i file_extension;... : include file extension eg. -i iso;wim will re-compress default file extensions and .iso and .wim file
   -o file_extension;... : re-compress only file extension eg. -o zip will re-compress only .zip file
   -n yes|no : do not backup (default : no)
   -t int : extract timeout (default : 900 -> 15mins)
   -p string : file password (use when archive is locked)
   -ca string : additional argument when compress for 7zip
   -ea string : additional argument when extract for 7zip

   Example :

   you can leave it alone like so

   > python py7zRecompress.py "C:\Users\Administrator\Downloads"
> python py7zRecompress.py "C:\Users\Administrator\Downloads" "C:\Users\Administrator\Documents"

   or you can do this

   > python py7zRecompress.py "C:\Users\Administrator\Downloads" -wt 2 -ct 8 -d 5 -s no -dc 128

   "C:\Users\Administrator\Downloads" :: scan files inside folder Downloads

   -wt 2 :: let program run 2 instance of 7zip

   -ct 8 :: let 7z compress file with 8 threads

   -d 5 :: let program look up compress-able file inside archive 5 times

   -s no :: re-compress any archive into .7z

   -dc 128 :: set dictionary size to 128m

   Note

   Deep parameter will very very slow if file/folder contains lots of file

   it will work even it's not efficient
