Spring supports reading from zlib zip and non-solid 7zip files. The filenames for these compression types must be .SDZ for zlib and .SD7 for 7zip respectively. They are standard files, just with different extensions for Spring. Here's a list of all filetypes supported by Spring; a higher read order means the contents of a file of that extension will take priority over files of a lower read order.

|1
|<b>SD7</b>
|Non-Solid 7zip
|A 7zip file with the extension changed to .SD7. 7zip compressed archives generally have the highest compression (and therefore lowest filesizes). Files of this type are read first.
|-
|2
|<b>SDZ</b>
|ZLIB ZIP
|A zlib ZIP file with the extension changed to .SDZ. Maps and games alike can be stored in these files. These are read second.
|-
|3
|<b>SDD</b>
|uncompressed
|A normal folder with the extension .sdd added. Used only during development because it is possible to test the game/map without having to unzip/zip it for every change.

The best tools to use to view the contents of a compressed Spring file, and
to pack and unpack the contents of such a file are:

*[http://www.rarlabs.com WinRAR] to view, browse, extract, and pack SDZ files, or to browse SD7 files.
*[http://www.7-zip.org/ 7zip] to view, browse, extract, and pack SD7 files.
