Damaged data can affect the entire Zip file, multiple files, or just one file. Among the most common is a transfer error when downloading a Zip file from the internet.
Such an error can introduce invalid data into a Zip file.
Some other possible causes include exposure of media to excessive temperatures or magnetic fields, cross linked disk sectors, and mechanical problems with disk drives.
The best solution to the problem of a damaged Zip file is to try to obtain another copy of the file.
When you add a file to a Zip file, Win Zip calculates a CRC value for the file and saves the value in the Zip file.
When you later extract the file from the Zip file, Win Zip calculates the CRC of the extracted file and compares it to the value stored when the file was zipped.
I actually support this idea, but I just wanted to point out there are minor downsides: a minor extra hiccup whenever subscriptions are updated, and a few extra MB to cache the pre-optimized copies of filter [email protected]: Ok, now I get it, but the solution for that is actually very simple: instead of deleting the redundant filters, just move them to a new (local) 'redundancies' list.This list would never be processed by abp, but would always be checked by the redundancy checker.That way you'd always be verifying the full set of filters, so redundant filters could always be retrieved at any time, and abp would still only process the unique filters, reducing it's work load.

In some cases, a partial file is of no use at all; in some cases, loading a partial file into your application program and re-saving it will completely restore the data.
