Just updated to 14.5 build 3051 BETA.
There are problems creating valid zip archives of larger sizes.
I needed to compress about 7 GiB of data and after finishing I opened the archive and I noticed I cannot find all my files in the newly created archive.
I tried to reproduce with another data, 5 GiB. The same results, not all files are found in the archive.
MC can open the archives and reports their size correctly. I know this because my files were not very compressible.
I used Double Commander to check the resulting MC archives and DC cannot open them, but DC can create valid archives out of exactly the same data.
Can somebody reproduce this? Just select some files until you make up about 5-7 GiB and then Alt + F5 and <Enter>.
