X This is the Info-ZIP file ``Where,'' last updated on 7 September 1994.

X
X Note that some ftp sites may not yet have the latest versions of
X Zip and UnZip when you read this. The latest versions, including
X the crypt sources, always appear in ftp.uu.net:/pub/archiving/zip
X (and subdirectories thereof) first.
X
X IF YOU FIND AN ERROR: please let us know! We don't have time to
X check each and every site personally (or even collectively), so any
X number of the sites listed below may have moved or disappeared en-
X tirely. E-mail to zip-bugs@wkuvx1.wku.edu and we'll update this file.

Xftp sites for the US-exportable sources and executables:
X
X NOTE: Look for the file names given above in the following directories.
X Some sites like to use slightly different names, such as zip-2.0.1.tar.gz
X instead of zip201.tar.Z. In the case of some comp.sources.misc archive
X sites, directories may be used (zip201/part01.Z, ..., zip201/part11.Z,
X zip201/patch01.Z, etc.).

Xftp sites for the encryption and decryption sources and/or executables:
X
X NOTE 1: Non-US users, please do NOT ftp from the US sites (US
X regulations and all that). Likewise, US users, please do not
X ftp from the European sites (it's not illegal, but it sure is
X a waste of expensive bandwidth).
X
X NOTE 2: Some sites may carry both encryption and non-encryption
X executables with slightly different names; for example, zip201c2.zip
X instead of zip201x2.zip ("c" == crypt version). Other sites may
X include *only* the encryption-related executables (zip and zipcloak)
X in a second archive (e.g., zcryp20x.zip).
X

X near you (although it always seems to find old versions...). If
X you don't know how to use it, DON'T ASK US--check the Usenet groups

X * it is conceivable that the DOS APPEND utility could be added to OS/2 some-

X * fore we simply check the filesystem at each path component.

X * Note that when alternative IFS's become available/popular, everything will
X * become immensely more complicated. For example, a Minix filesystem would
X * have limited filename lengths like FAT but no extended attributes in which
X * to store the longer versions of the names. A BSD Unix filesystem would
X * support paths of length 1024 bytes or more, but it is not clear that FAT
