7-Zip

We use the freeware 7-Zip:

• Uncompression of Unix TAR and GZ files
• Extract ESRI Layer Packages, which is probably the safest and easiest way to transfer data from ArcGIS.
• Compress and uncompress BZIP2 files.
• It will also deal with RAR files, if you have students who think that is a good format.

You must install this program (there are both 32 bit and 64 bit versions; get the appropriate one for your OS), and put the 7z.exe and 7z.dll files in the MICRODEM program directory.
