Why we use ZIP
A Zip format allows either extremely large files, or files created in formats no longer widely used, to be combined and compressed and thus downloaded with more speed and ease. The user requires an "unzip" utility to extract files from an archive (all files for downloading have been compressed using zip archiving and compression). IES uses Zip archiving for several of its newer applications, such as video, and for many data sets. In addition, some older reports are available only in a combination of file formats, such as Lotus .WK1 format for tables and plain ASCII for the text.
The time it takes to download a file depends on the size of the file and your connection speed. To estimate the time required to download a file we have provided a link to a "File Download Time Calculator."
