[DISCUSSION] How to extract embedded zip/rar files recursively in one step?

(1/3) > >>

vixay:
This has been bugging me for a while...
Often when you dowload something it is compressed multiple times and is very annoying to extract.
e.g.

--- ---xx.zip
-yy1.zip
--yy1.rar
---zz.exe
-yy2.zip
--yy2.rar
---zz.exe
-yy3.zip
--yy3.rar
---zz.exe
So for the above case which shows the directory structure of xx.zip file. Now how can i extract zz.exe in one step, without having to first extract xx.zip, then all yy#.zip, then yy#.rar?

I have beel looking everywhere! Unrar can extract embedded files, but not split embedded files... don't ask me to explain, try it yourself.

anybody have any ideas/suggestions?

Actually i figured out one script that works for me

--- ---@echo OFF

SET "dir=."
SET "ext=*.zip"

winRAR x -o+ %1

FOR /r "%dir%" %%* IN (%ext%) DO (
  winRAR x -o+ "%%*" "%%~dp*"
  del "%%*"
  )

winrar x -r -o+ *.part1.rar
del /s *.part?.rar
but this works only for a specific case (i.e. where you have an archive in which you have zip files in which you have rar files)
can it be improved to work for all cases?

AbteriX:
Allways the same structure?

Maybe with an batch.cmd:
C:\>UNPACK *.zip  INTO STEP1
CD STEP1
C:\STEP1>UNPACK *.zip INTO STEP2
CD STEP2
C:\STEP1\STEP2>UNRAR *.rar INTO STEP3
CD STEP3
C:\STEP1\STEP2\STEP3>EXTRAXT *.exe INTO STEP4
... to be continue

vixay:
Actually, no. That's the whole point! I want something that works with all cases (not a specific case)
The script i provided works for a specific case of zip/rar(zip(rar)))

And i want to preserve the directory structure, and remove the intermediate files.

So let me restate my objective: Extract all archives from within an archive (passed parameter) and/or directory (i.e. recursive), while preserving directory structure and deleting intermediate files generated.

Save the following code in a batch file with the name extract3levels.cmd

--- ---@echo OFF
REM //Set up some variables
SET "dir=."
SET "ext=*.zip"

REM //Extract the passed file, to current directory
REM //overwriting files.
winRAR x -o+ %1
REM //Should have a graceful error case here to make sure the operation completed
REM //successfully, if not then exit script... how to do this?

REM //Now in the current directory extract each zip file into its folder
REM //Delete the file after extracting it
FOR /r "%dir%" %%* IN (%ext%) DO (
  winRAR x -o+ "%%*" "%%~dp*"
  del "%%*"
  )

REM //Now search for a file ending with part1.rar in all subdirectories and extract it
winrar x -r -o+ *.part1.rar
REM //Delete all files ending with a part?.rar in all subdirectories
del /s *.part?.rar

REM Usage:
REM program_name <archive>

 the above script works, but maybe what i want needs a more flexible language, maybe autohotkey can do this...?

Hmm.. Total Commander handles that for me. Since it "opens" archives as directories/folders, all you have to do is keep pressing enter/clicking on it till you get to the actual file. Then you can drag/copy it out to the desktop (or wherever) or to the other windowpane. So far I have tested with multi-level combinations of zips and rars nest in each other, 6 archive deep.

That's ok. Even winrar can do that. with only 1 archive embeded (no matter how many levels) it is ok to do this, but what about when you have 5 archives in 1 archive, and then in those 5 archives you have 1 archive each, but that 1 archive is a split archive... so to extract the files, you need to get all those 5 archives hidden within each of those split archives and then extract them.. sigh, i guess i am not making much sense, let me see if i can whip up a sample for you...
