Validate ZIP before opening it
Posted: Tue Feb 28, 2023 11:20 PM

Hello friends of the forum:

Is there a function in Harbor that allows you to check if a ZIP file is damaged or corrupt?

before trying to open it?

hi,

every "Packer" have Option

-t Test .ZIP file integrity

---

as long "Standard" Compression is used all "Packer" can handle it but when change Compression Mode there might be Problem
but "max" Compression is not real need any more since "big" HDD/SDD and quick Internet

so "just use ZIP as "Envelope""

greeting,

Jimmy

Just try to unzip the ZIP file with HB_UNZIPFILE() and check the return value.
