From videos and family photos to old school papers and signed contracts, there are many files on your computer that you don't use a lot, but you don't want to give up either. Fortunately, you can compress the files into smaller data packages and archive them. When you need them again or want to view them, you open them up.

The software uses RAR and ZIP formats to help you achieve the information that you aren't currently using on your computer to free up space on your hard drive. The files become depressed, so they aren't as large as they once were, giving you more storage space.

When you're ready to start archiving files on your computer to make room by compressing files you rarely use, WinRAR is an option to get the job. However, if you need more versatility, you might opt for a different software, such as WinZip.

First use the winrar to compress it with the best mode. Then archive it with 7zip. I tried it with gta sanandreas with a size 5.79 GB and after compression it got reduced to a memory of 12MB. Believe me, it's working.

You can right-click the files you want to add into your archive and click "Add to archive..", on the Compression method click "Store" and on the "Split to volumes, size" type the size you want. You can also change it to Bytes, KiloBytes, MegaBytes and GigaBytes

File compression is an important part of digital storage management. Computers and especially mobile devices have limited storage. Being able to compress files to make them smaller is a good way to free up some much-needed storage space. Furthermore, many email applications limit the size of a file that can be added as an attachment. Compressing a file before adding it as an attachment may allow you to send a file that would normally be too large to send. However, there is a limit to how much a file can be compressed, and compressing a file often reduces the quality of the file. This wikiHow article discusses how to compress files, and the limitations of file compression.

One of the main functions of WinRAR is to compress files. This way, they can be shared or stored more easily. To reduce the size of one or more files, you must run WinRAR, and using the integrated browser, locate the files you want to compress. Select them, and then, click on Add.

In the window that will appear, check Create solid file box. Also, select Best from the drop-down list under Compression method. Both options will help you maximize the compression and reduce the final size of the file created by WinRAR.

Enable the Force options you will see in the Text compression, Audio compression, and True color compression sections. These settings only apply to RAR4 files. Therefore, make sure you have chosen this format on the main screen. To apply the changes, use the OK button.

When finished, WinRAR will have created a compressed file in the directory you specified. You need to know that the compression applied will be bigger for larger files. Therefore, if you try to compress a photograph, a text document, or a song, the final results will be hardly noticeable.

WinRAR, a Windows utility to condense and expand files, is installed on college-administered Windows computers. Use WinRAR to backup and compress data, reduce the size of attachments you want to email to others, uncompress RAR, ZIP, and other files downloaded from Internet, and create new archives in RAR and ZIP file formats.

To extract files from a compressed format, right click on the file and select Extract files... or Extract Here or Extract to filename (shown). Extract files... lets you choose where the extracted files will be saved. Extract Here puts the files in the same directory as the compressed file. Extract to filename creates a folder with filename in the current folder and puts the extracted files there.

You can also go to Start All Programs WinRAR, then use the file browser to locate the compressed file or folder. Select the files or folders that need to be extracted and continue as above.

Because disk quota is always a finite resource, you may find that you need to archive files to free up space for other files. You can put archive files on a floppy disk, a ZIP disk, a flash drive, a CD or DVD, as well as leaving them on the local hard drive or network drive. Another reason to compress a file is to email a large file to someone whose mail space does not allow receiving a file as large as the uncompressed version. In both cases you can use WinRAR to compress files.

Go to Start All Programs WinRAR to start the program. Use the file browser to change directories to the location of the file(s) or folder(s) you want to compress. Select the file(s) or folder(s); press the Ctrl key to select multiple files/folders. Click the Add icon at the top of the window or go to Commands Add files to archive or press Alt + A. The Archive name and parameters dialogue box (shown ) opens.

-md=29 - Sets Dictionary size for LZMA. You must specify the size in bytes, kilobytes, or megabytes. The maximum value for dictionary size is 1536 MB, but 32-bit version of 7-Zip allows to specify up to 128 MB dictionary. Default values for LZMA are 24 (16 MB) in normal mode, 25 (32 MB) in maximum mode (-mx=7) and 26 (64 MB) in ultra mode (-mx=9). If you do not specify any symbol from the set [bkmg], the dictionary size will be calculated as DictionarySize = 2^Size bytes. For decompressing a file compressed by LZMA method with dictionary size N, you need about N bytes of memory (RAM) available.

-ms=8g - Enables or disables solid mode. The default mode is s=on. In solid mode, files are grouped together. Usually, compressing in solid mode improves the compression ratio. In your case this is very important to make solid block size as big as possible.

I had 10 folders with different versions of a web site (with files such as .php, .html, .js, .css, .jpeg, .sql, etc.) with a total size of 1Gb (100Mb average per folder). While standard 7zip or WinRar compression gave me a file of about 400/500Mb, these options gave me a file of (1) 80Mb, (2) 100Mb & (3) 170Mb respectively.

Update edit: Thanks to @Griffin suggestion in comments, I tried to use 7zip LZMA2 compression (dictionary size seems to have no difference) over the 7zip WIM file. Sadly is not the same backup file I used in the test years ago, but I could compress the WIM file at 70% of it size. I would give this 2 steps method a try using your specific set of files and compare it against method 1.

Do the duplicated files have the same names? Are they usually less than 64 MB in size? Then you should sort by file name (without the path), use tar to archive all of the files in that order into a .tar file, and then use xz to compress to make a .tar.xz compressed archive. Duplicated files that are adjacent in the .tar file and are less than the window size for the xz compression level being used should compress to almost nothing. You can see the dictionary sizes, "DictSize" for the compression levels in this xz man page. They range from 256 KB to 64 MB.

A solid archive with a larger dictionary size in combination with best compression can make an archive file with a list of similar files very small. For example I have a list of 327 binary files with file sizes from 22 KB to 453 KB which have in total 47 MB not included the cluster size of the partition. I can compress those 327 similar, but not identical files, into a RAR archive with a dictionary size of 4 MB having only 193 KB. That is of course a dramatic reduce of size.

You have to take care also about option Files to store without compression in case of using GUI version of WinRAR. This option can be found after clicking on symbol/command Add on the tab Files. There are specified file types which are just stored in the archive without any compression like *.png, *.jpg, *.zip, *.rar, ... Those files contain usually already the data in compressed format and therefore it does not make much sense to compress them once again. But if duplicate *.jpg exist in a folder structure and a solid archive is created it makes sense to remove all file extensions from this option.

By the way: There are applications like Total Commander, UltraFinder or UltraCompare and many others which support searching for duplicate files by various, user configurable criteria like finding files with same name and same size, or most secure, finding files with same size and same content, and providing functions to delete the duplicates.

As you all know a disadvantage of Xamarin Forms apps is their huge size. Though I went through different scenarios for reducing app size such as Linking and using Proguard, my Android APK size is still so high(about 30 MB). The thing is when I compressed this apk by Winrar the size got to about 11 MB. I renamed this compressed .rar file to .apk file but when I tried to install this file I got the message: "There was a problem parsing the package".

WinRAR fully supports creating and extracting ZIP archives, so choosing WinRAR doesn't mean you'll be forced into using the RAR compression format. But you should use it, because RAR, as a compression format, clobbers ZIP. It produces much smaller archives in roughly the same time. If you're worried the person on the receiving end of the archive won't have a RAR client, you can create a self-extracting executable archive (or SFX) at a minimal cost of about 60 KB additional filesize.

RAR also supports solid archives, so it can exploit intra-file redundancies. ZIP does not. This is a big deal, because it can result in a substantially smaller archive when you're compressing a lot of files. When I compressed all the C# code snippets, the difference was enormous:
