The XMIT format is with a high degree of certainty supported on every
platform that has Java:
<https://github.com/dmolony/Xmit>, and I'm sure the C version on the
CBTTape site (File # 776) will compile on any system, although that
program can only handle PDS'es.
FTP of a PDS won't preserve all of the data. Does Info-Zip include
all of
the directory information? Also, FTP raises the issues of binary
data and code pages.
Not just FTP. IND$FILE and the WSA have the same problems.
XMIT files are somehow supported on PC side for decades. There are
several programs for that, most of them are free and unfortunately most
of them are abandonware.
However they exist.
What does it mean?
1. You can read members from XMIT'ted PDS(E).
2. Of course members can be saved files in directory/folder - PDS is
kind of folder. However in this case EBCDIC-ASCII conversion issues do
apply.
3. In few cases a content of PDS directory is interesting. In that case
XMIT tools are not helpful. However let's be honest: what is the value
of accessing PDS directory details on PC side? Usually it is interesting
for load modules or program objects. Rather not interesting on PC side.
4. Philosophical question: do we care about content or just 100000%
exact bit to bit copy? Do you want to know members content or you also
care about PDS bitmap before it is compressed (in terms of PDS compress)?

My choice is XMI Explorer. The second one is Xmit-Manager.
In my opinion java-based tools are doubtful choice because of changes in
java status.
