I use a mac and have a zip file that contains a base set of files that I use over and over. Every time I need the set of files for a new project, I simply unzip the zip file and they are ready for use. I have unzipped the same zip file over and over again. I have never received an error or corruption alert, but am wondering if unzipping the same zip file repeatedly will cause any data corruption. Thanks!
Can a Zip File Become Damaged from Repeated Unzipping

It's unlikely that the act of unzipping a file will cause any kind of corruption since decompression is a read-only process. However, there is a small chance that repeated access to the file over long periods could cause the disk sectors on which it resides to become corrupted, since it is a magnetic medium and is subject to wear. To mitigate that risk, you can periodically copy the file to another storage device, delete it on the original disk, and copy it back to the original disk. This will (most likely) result in the file being written on different sectors.
