How to Create a RAR File
RAR files are a form of compressed data files, similar to a Zip or Zipped file. Data compression is used to shrink file sizes so as to save space on a hard drive (or portable drives such as a USB Thumb Drive) or to decrease the time it takes to send a file across the Internet, either as an attachment to an email message or as a file stored on a website as a download.In order to create a RAR (compressed) file in Microsoft Windows or to \"Expand\" (otherwise known as extract or decompress) a RAR file you will need a software program that will handle this type of file for you. Fortunately, there are several easily obtainable software packages that will answer this need, either available a \"shareware\" (try before you buy) or \"freeware\" which is available for free.
Locate the file you wish to compress into a RAR format by (Microsoft Windows) opening up My Computer, clicking on the C:\\ drive (or in systems that have multiple drives, whichever drive the file is located on) and then clicking on the folder where the file is located.
Highlight the file with a single click of your left mouse button. Right click and choose \"Create Archive.\"
Add a password to your file to secure to protect your information by clicking on the Edit menu and choosing Password. (Please note that the password option may be under a different menu heading depending on which RAR program you have installed.)
Double click the file to extract it and answer the onscreen questions as to where you want the extracted file saved. (Please note that you will be prompted for a password if one is required during this process.)
Use the newly extracted file by opening it with the required program as you would with any other file of the same type.
Tips & Warnings
- Archiving your unused files will save disk and when password protected will discourage unwanted snooping.
- RAR files can contain a virus which your anti-virus software cannot recognize until it is extracted.
