Hi All,

Is there a way to unzip a password-protected file using InDesign JavaScript?

Please provide some examples if possible.

Thanks,

Google this:

javascript unzip password

And you'll get the answer(s) you're looking for. You're not going to like them very much I don't think but that's your lot.

You can unzip a zip file using unpackageUCF():

app.unpackageUCF (
  File ('myZip.zip'),
  Folder ('d:/unzipped/')
);

Though probably password-protected zip files will be refused, but that will be the case with all unpackers. You'll have to look for a utility that allows a password as an input parameter, and you'll have to get the password from the party that produced the zip file.

Thanks Peter! it's working fine for files without a password. Do you have any suggestion for any utility that support password, I am unable to find out. I just got zip.js but it's not working with InDesign and getting attached error.

What is wrong with my example?

You just need to find unzipping tool, check params for it to unzip password protected files and then build string to use in my example?

Similar principle for Mac - you just need to Google it.

There are some examples for Windows:

Something similar should be somewhere for Mac.

You would have to use an external language that can perform the unzip function then call an Extendscript routine on the unzipped packaged.

A lot of files are actually ZIP archives (EPUB, MS Office, etc.) and have to be accessed through an archive opener. I'm pretty sure there are standard code examples and library routines for both regular ZIP and PW-protected ZIP files out there; not sure if they mesh with ID's version of things.

I've been looking for a good module to do just that, for other purposes, preferably with seamless PW control built in. Haven't found one, but I'm feeble on JS, my programming era being a while back.

Thanks James for your reply!

Zip and Unzip using InDesign JavaScript is possible but I am looking if we can extract a PW protected zip file using InDesign JavaScript.

Thanks,

If you're on Mac then you can use the unzip shell command. I don't know if shell scripts can be called directly from JavaScript, if not then you'll need to use doScript command in JavaScript to call do shell script AppleScript.
