We have an old application that requires zip files to be "legacy" format. I would really love to get rid of the adware ridden WinZip and use 7zip. However, I don't know which compression options and such equal out to "legacy".
How to do it?
For reference the compression methods I have to choose from are
- Deflate
- Deflate64
- BZip2
- LZMA
- PPMd
Or does which compression method I use even matter? Would it all end up going in as a "legacy" zip file anyway?
Best Answer
Legacy zip compression is akin to the Deflate method in 7-zip, and will offer the most compatibility between different compression software.
