How to compress data as much as possible?

Question

Data archiving

There is a folder with installed game files, 10.5GB in size, you need to compress to 7.5 (to write to a USB flash drive). Tried through WinRar, setting the maximum compression in the settings, but the archive turned out to be 11+GB. Please advise how to compress files as much as possible

Answer 1

So the game files are already packed. There is not much benefit from archiving the archive.

Answer 2

There are several options -
1) Split into two parts and move in two parishes. The same WinRar allows you to select the size of the parts
2) Try another archiver - for example 7-zip
3) Some games allow you to "compress" the content - for example, textures or videos (or delete it altogether). But it needs to go from the game.
4) Take another larger flash drive
5) Pull the hard drive out of the computer and go with it. The main thing is not to drop.
6) Transfer over the network (transfer through any cloud storage - dropbox, onedrive, yandex.disk, etc., or raise a server and give it through it (for example, hfs)).
7) If the game is not some kind of rarity, then you can pack up to 100-200 kilobytes. To a torrent file.

Answer 3

It all depends on the type of data, perhaps they are already highly compressed.
Try in WinRar in the settings to set the following
- Compression - maximum.
Archive format - Rar5
Dictionary size 1GB
Archive - continuous.
This operation will require 8GB of free RAM.

Answer 4

Read what "deduplication" is. Useful thing.
Source files (uncompressed and unencrypted) usually contain small repeating blocks of data. And the target compression algorithm should not be used ultra, but simply strong compression, because it will compress very slowly, but there is little sense.

Answer 5

I was just thinking about the same question. I plan to create a small partition on the HDD, up to 4Gb, put the necessary files on it (some possibly winrar ones), then make an image of this HDD partition using Acronis True Image (you can, of course, do something else). As shown in the case of a 10Gb partition, after creating an image of this partition using Acronis True Image, the image began to occupy something around 1.7Gb - almost 6 times. But the section is not completely written with data (somewhere a little more than half).
I'll try to do it with a 4Gb partition, initially resorting to Winrar (to files), then I'll make a disk image, then I'll make an image again from the created image.
It is very interesting whether this will work, and whether the original content will work later.
As I try - I'll try to write what happened.
