Re: Recursive zipping of Directories in Windows

Hi

I am a python novice and I am trying to write a python script (most of
the code is borrowed) to Zip a directory containing some other
directories and files. The script zips all the files fine but when it
tries to zip one of the directories it fails with the following
error:
"IOError: [Errno 13] Permission denied: 'c:\\aaa\\temp'"

The script I am using is:

import zipfile, os

def toZip( directory, zipFile ):
"""Sample for storing directory to a ZipFile"""
z = zipfile.ZipFile(
zipFile, 'w', compression=zipfile.ZIP_DEFLATED
)
def walker( zip, directory, files, root=directory ):
for file in files:
file = os.path.join( directory, file )
# yes, the +1 is hacky...
archiveName = file[len(os.path.commonprefix( (root,
file) ))+1:]
zip.write( file, archiveName, zipfile.ZIP_DEFLATED )
print file
os.path.walk( directory, walker, z )
z.close()
return zipFile


if __name__ == "__main__":
toZip( 'c:\\aaa', 'c:\\aaa\\test.zip' )

I have tried to set the permissions on the folder, but when I check
the directory permissions it is set back to "Read Only"

Any suggestions?

Thanks

Couple of quick suggestions that may help:

1) don't use 'file' as a variable name. It will mask
the builtin file function. If it hasn't bitten you before
it will if you keep doing that.

2) If you put the target .zip file in the directory you are
backing what do you expect the program to do when it comes
to the file you are creating as you walk the directory? You
haven't done anything to 'skip' it.

3) Your commonprefix and +1 appears to result in same
information that the easier to use os.path.basename()
would give you. Double check me on that.

I don't see anything that references C:\\aaa\temp in your
code. Does it exist on your hard drive? If so does it
maybe contain temp files that are open? zipfile module
can't handle open files. You must use try/except to
catch these errors.

Hope info helps.
