Leaving aside the alarming 4GB limitation i am also experiencing data loss with small archives, i am uploading a sample archive that contains one 674 MB file.

When downloading this archive with Safari it automatically gets decompressed by what i assume to be the same framework as Archive Utility to a mere 114.6 MB.

Decompressing this small archive with Archive Utility however properly yields the 674 MB file
