This guide will tell you how to change the extensions of files. This is mostly for people having trouble changing .zip files to .jar files.

To change the extensions of files follow this method (using windows):

1 - open any folder
2 - click on tools > folder options
3 - select the "view" tab
4 - make sure that "hide extensions for known file types" is de-selected.
5 - rename your file to "filename".(extension)

*make sure to re-select "hide extensions for known file types" after you're done. This is for your safety as others using the same PC may mess up your files.

If ALL that doesn't work, then try THIS application by Err0r bash.gif
