Can zdelta handle large files?
Although zdelta can compress and decompress correctly very large files, it could sometimes have poor performance on files larger than 100kb. The problem stems from the fact that for efficiency, zdelta computes the difference between the reference and the target file using only 64kb windows at a time. Currently the library employs a simple window synchronization/movement technique. As a result it is possible that the windows loose synchronization. In such cases zdelta will act as a conventional LZ77 compressor. We are currently working on resolving this issue.
