"Error: bad offset 0x1532FDFA at end of '1.zip'"

[Fefolino]

Hi all, I am try to running this script on Windows 10 on a .zip file that gives "Warning: 32-bit overflow in headers" but it gives me this error

"perl fix-onedrive-zip 1.zip

Checking '1.zip' Error: bad offset 0x1532FDFA at end of '1.zip'"

Can you help me please? Thanks!

Hey @Fefolino

need some more info to see if I can help you

Is this a zip file created by OneDrive or Windows Zip? The error you are getting suggests it might not be, but you never know. If it isn't a OneDrive/Windows zip file, do you know how it was created?

What program are you using to unzip the file? Is it 7Zip?

Can you share some details about the version of Perl you are running please? Run the command perl -V and post the results here. Note that the capital V in the command.

I don't know how that zip was created sorry :/ Yes, I am using 7Zip to unzip it.. This is the result of perl -V, I downloaded the last version

What you have is a zip file has been probably created by something other than OneDrive. To verify that I would need more data about the zip file - to get that can you need to run another script of mine.

Download https://github.com/pmqs/zipdetails/blob/main/bin/zipdetails and run as follows

perl zipdetails -v 1.zip

That may output a lot of data, depending on how many entries are in this zip file - see if you can upload in here. I

I have the same error. I think I compressed(made the zip file) on a mac, uploaded to Onedrive and now I'm trying to unzip the file on a windows.

7-zip warning: Warning: 32-bit overflow in headers

The programs output: Checking 'UCOR 1300.zip' Error: bad offset 0xFB35C190 at end of 'UCOR 1300.zip'

Hey @mjhymowitz

the bad offset error means the zip file isn't in a state that this program expects for fixing the specific OneDrive issue.

If your file, UCOR 1300.zip, was created on a Mac, uploaded to OneDrive, then downloaded to Windows, I'm doubt that OneDrive hasn't messed with it. I'd guess that the issue is with how the Mac created the zip file. To confirm that you could try copying the MAc zip file directly to a windows machine ad see if the same issue is present.

There is (or was) an issue with Mac created zip files > 4Gig files not being created properly that I' aware of. If you want help confirming that you need to upload the zipdetails data I've asked for in the post dated the 21st Jan.
