Native support was added as of the year 2000 in Windows ME. Microsoft has included built-in ZIP support (under the name "compressed folders") in versions of Microsoft Windows since 1998 via the "Windows Plus!" addon for Windows 98. The ZIP format was then quickly supported by many software utilities other than PKZIP.

This format was originally created in 1989 and was first implemented in PKWARE, Inc.'s PKZIP utility, as a replacement for the previous ARC compression format by Thom Henderson. The ZIP file format permits a number of compression algorithms, though DEFLATE is the most common. A ZIP file may contain one or more files or directories that may have been compressed. ZIP is an archive file format that supports lossless data compression. Step 7: Once you have your conference's certified PDFs, you are ready to prepare the Conference Content for the IEEE Xplore Digital Library.ISO/IEC 21320-1:2015 (a subset of ZIP file format 6.3.3) If the dates don't match, inform the author that the PDF cannot be accepted because the modification may have jeopardized Xplore compatibility. Step 6: Each PDF needs to be checked to verify that the creation date matches the last modified date. Step 5: As soon as your authors verify that their PDFs are Xplore-compatible, they send these PDFs to you or your production team, or the conference organizer can choose to download the files online.

These instructions reference the conference's Letter of Acquisition and address the requirement of placing the appropriate copyright footer on each article. Step 3: After the PDF eXpress site has been created, IEEE PDF support provides you with instructions to post on your conference website for your authors. Step 2: A customized PDF eXpress web page is created and is available exclusively to your conference authors. Step 1: The Conference Organizer requests a PDF eXpress site when completing the IEEE Conference Publication Form.
