Do you wish to compress files so that it can transfer easily between storage devices, or when you want to upload it to an email or how about when you just want to save precious hard drive space when storing files.Well, now you can just do that.
WinRAR is a powerful archive manager. It can backup your data and reduce size of email attachments, decompress RAR, ZIP and other files downloaded from Internet and create new archives in RAR and ZIP file format. You can download the trial version of the software at www.rarlab.com
To compress large file using Winrar follow simple steps given below:
Step 1: Select and Right click on the file you want to Compress and select Add to Archiveoption.
Step 2: A window will pop up with various options. In Archive name field type the name of your archive manually in the text box provided below.
Step 3: When creating a new archive, you first need to select the archive format. ZIP is preferable when you are not sure that a receiver of your archive has WinRAR. Otherwise just select RAR, since it provides more options and higher compression.
Step 4: There are six compression methods supported: "Store", "Fastest", "Fast", " Normal", "Good" and "Best". The Best method provides high, but slow compression. Fastest method compresses poorly, but it is very fast. Store method just merges files into an archive without any compression. If you want to create an archive for distribution or for long storage, It would be best to probably ignore the time constraint and choose the Best compression method to reduce the size as much as possible. But for daily backups choose Normal compression method.
Step 5: At the bottom there is a Tab saying “Split to Volume, Bytes” In the box enter a figure or you can use the drop down menu to make your choice. Remember you have to enter the value in bytes, kilobytes or megabytes and this applies only to .rar extension. (1024 KB equals 1 MB)
In the example below, I have chosen 98078 KB which comes to around 95.77 MB.
Step 6: When you have chosen the right options for your archive, click the OK button.
(In my example below, the video file I had chosen was compressed into three parts comprising of 95.7 MB each)
