rename files in zip folder using zipmodule

Question

I was wondering if anyone knows how I can rename a file called "logo.png" in my zip folder under ("fw/resources/logo.png") to ("fw/resources/logo.png.bak"), using python's zip module.

You can't with the built in `zipfile` module. – agf Sep 15 '11 at 09:15 — agf, Sep 15 '11 at 09:15

As mentioned by rocksportrocker, you cannot rename/remove a file from a zipfile archive. You would have iterate over the files in the zipfile and selectively add the files you want. So to remove a certain directory from the zipfile, you would not copy them to the new zipfile. That would be something like this:

source = ZipFile('source.zip', 'r')
target = ZipFile('target.zip', 'w', ZIP_DEFLATED)
for file in source.filelist:
    if not file.filename.startswith('directory-to-remove/'):
        target.writestr(file.filename, source.read(file.filename))
target.close()
source.close()

As this would read all the files into memory, it would not be an ideal solution for large archives. For small archives this works as advertised.

Does it really load the whole file in memory? – swdev May 04 '15 at 10:45 — swdev, May 04 '15 at 10:45

I think that is not possible: the zipfile modules has no methods for that, and as mentioned in Renaming a File/Folder inside a Zip File in Java? the internal structure of zip files is in the way. So you have to do unzip, rename, zip.

Update: Just found Delete file from zipfile with the ZipFile Module which should help you.

deletion can be done with os.rmdir of shutil.rmtree, but if you only want to rename a folder, us can use shutil.move – rocksportrocker Sep 15 '11 at 11:09
