Compress a back-up?

[bvergara]

I have backed up a shared folder on a "server". I need to save it to a disk,
but the file is too large. How do I compress the file or which program
should I use to compress a file?

The easiest way (on NTFS partitions) is to make it "compressed", to do this,
right-click on the file, choose properties, and click on advanced and choose
"compress this file to save disk space".
