Lomography's LomoChrome '92 is designed to mimic the look of classic drugstore film that used to fill family photo albums. As we discovered, to shoot with it is to embrace the unexpected, from strange color shifts to odd textures and oversized grain.
The Compress-Archive cmdlet uses the System.IO.Compression.ZipArchive API to compress files.The API limits the maximum file size to 2GB. For more information, seeSystem.IO.Compression.ZipArchive.
The Compress-Archive cmdlet ignores hidden files and folders when creating or updating thearchive file. On non-Windows machines, this includes files and folders with name that begins withthe period (.) character.
I was surprised to find that it had the exact opposite effect on free disk space. I tracked it down further and found that it is related to compressing the Help folder. The loss of disk space is not reflected in the folder size.
After compression "Size" is still the same as the amount of net data has not changed at all. However compression was able to reduce the total size about 130MB. In fact even more because the overhead here also applies. So compression did actually save some space in that folder and that is also displayed in the folder size.
Having recently researched a similar problem, I can also say that a compressed file takes at least 4 kilobytes of space per file, and a temporary space of 64 kilobytes, which is the size of one "Compression Unit" for NTFS with 4kb cluster size. The article on blogs.msdn.com also mentions that when the file is compressed, the disk space is allocated to hold one full CU, and is released at undetermined time. This should be the reason of why you are experiencing the loss of 5GB, albeit temporary (a reboot should definitely fix that loss, some other means should do that too, but not defrag - have tried and failed). Apparently what's allocated seems to be a lot bigger (64kb*(31048+582) = 2072903680 or 1.93 GB), but this is explainable as NTFS has transactions which take time and processor units to be committed into raw data, and when that process will be finished, you will get all 5GB plus 150 MB space released due to compression back.
Server migration, I copied the data folders of a drive of the old Windows Server 2012R2 (with 2 compressed folders) on a newer Windows Server 2016 Datacenter drive of the same size where I created the folder structure and set the compressed flags on these two folders previously to the copy process. During copying I run out of diskspace, and anywhere I looked only 3GB of 20GB are used, but the drive itself tells me 19.x GB are used. A colleague told me to remove the compression flag, and miraculously the lost 17GB reappear.
I guess there could be an issue in Windows Server 2016 (maybe since ever) that internally generated temporary files are not cleaned up properly when files are copied to a compressed folder (as opposed to when the compression flag is applied to already existing files).
Adjunct: In addition to the explanations above, an application folder can contain files that simply do not compress well - already strongly data-reduced media formats (jpeg images, video files, mp3 audio...), already compressed files (a lot of data formats these days are built as ZIP archives!), files with actually random data or something resembling random data in them, encrypted files - this might result in there being more data being used for bookkeeping of what's been compressed than was saved by compression....
Also to note if you are on the DXC and the performance issues are around mobile and download sizes it should be automatically compressing your images for you using the Cloudflare polish service. You might want to check your headers to make sure it's working -reed/dates/2018/5/dxc-automatic-image-optimization/
Please have in mind that in this example we're reducing the quality of the file, not the image dimensions. Which will result in a compressed file that it's not visually affected when rendered on screen, but you will see the artifacts when printing in a big paper size (bigger than letter).
Now. We can do a different thing. A couple of things indeed: We can first resize the images and apply compression after that, which will result in a smaller file size than the original, and will deliver a useful image for rendering on screen, not so good for printing but it seems we need to display it on screen and not in a printed banner, right?
If we wish to maximum compress a maximum compressed file like this, we'll face some overhead data inserted in the file and it will result in a bigger file size. So I won't suggest you to try but if you are expecting me to do the example, ok... Here we go!
And we went from a 433.7 KB to a 176.2 KB in a single command. This example was successful, nevertheless don't expect any exercises to result in smaller file sizes. But you can have lots of fun when running this kind of exercises.
If you are referring to jpeg images, de facto compression is not possible. Because jpeg is by definition a compressed file format (all noise and useless pixels are already removed). You can zip them alright, but the total size will remain about the same. The only advanced compression algorithm i know for jpegs is zipx. But zipx is proprietary by Winzip and ensures a max. size cut by 30% (in zipx archive mode).
To display your images on the web, first you should resize them (under 1MB per each one) and optionally convert them to png file format. PNG(=portable network graphics) is specially optimized for faster web transfer and faster display. Advanced users may even convert those images to webp format (Google's format for pictures, fastest loading algorithm).
I like this, but I still want images at 1920x1080. Wondering what the impact would be on setting Run 1's New Dimension to 100% instead of 70%? My images folder is 156 GB! I was expecting around 75-100.
One way to store more data when you are low on hard drive space is by using compression to make the files and folders you already have on the drive take up less space. In the past, utilities such as Winzip were used for this purpose, but Windows XP has a built in compression utility that does the same job.
To create a compressed folder, open My Computer and locate the folder where you want to create the compressed folder (also known as an archive). Open that folder, then select File, New, Compressed (zipped) folder.
Compressed folders even support a password option, allowing you to use them as a place to store sensitive information. You should be careful when using this feature, however. The password is not recoverable. If you forget it, your data stored in the compressed folder will be lost forever. To add a password, open the compressed folder and select File, Add a Password.
In addition to the compressed folders feature, Windows XP supports another type of compression if your hard drive is formatted as an NTFS volume. You can see it if your hard drive was formatted with NTFS by opening My Computer and then taking a look at the details section on the lower left.
NTFS compression differs from compressed folders in that the NTFS compressed folders appear like any other folders. The operating system compresses and decompresses them on the fly each time you access and close them. NTFS compressed folders do not have a zipper on their icon. However, you can set up Windows to display them in a different color if you want to know which folders are NTFS compressed and which ones are not.
If you want to display your NTFS compressed folders using a different color, select Tools, Folder Options from an Explorer window. Then in the View tab, make sure Show encrypted or compressed NTFS files in color is checked.
It's not a surprise that the largest files on your Mac are probably your videos. So, whether you're running out of space on your hard drive or trying to send a movie that's too large, compressing videos is a great way to reduce their file size. And with no shortage of options, figuring out where to start with it all can feel overwhelming.
Compressing videos on Mac is a balancing act. Because even if you compress a video ever so slightly, there will still be some quality loss. It's all about finding how much you can compress it to reduce the file size without noticing that the video is actually of lower quality.
Arguably the most popular compressor, Handbrake has been around for years. And it's popular for a reason. It's a simple, free video compressor for a Mac. Once you have Handbrake downloaded and installed in your Applications folder, you can follow these steps to compress a video:
Another option you have is the free online compressor, Clideo. As long as the video you want to compress is already under 500 MB, you can upload it using your browser, and Clideo will do the rest. And the best part is there's no software to install. Here's how you compress your videos with Clideo:
While it might feel like a daunting task at first, reducing video file size on Mac doesn't have to be scary. And the good news is you have a couple of different options. Whether you decide to use one of the default apps or one of these free tools, hopefully, you're feeling confident in compressing your videos on Mac after reading this article.
I imported roughly 1.3 GB worth of textures into a blank project (thirty-three 8192x8192 textures), and made a material for 11 of them (because the other 22 were the specular and normal maps of the material) and the final build size (even with compressed cooked content) was about 890 MB. And the project folder size was 10 GB! Is it normal for Unreal Projects to be this huge?
All AAA games and UE4 with defaults settings use compressed textures.(DXT) This make texture already 4 to 8 times smaller in size. Cooked package is also compressed which further reduce size of textures around to 50%. Atlases does not save any space and actually can waste memory because of inefficient packing and required padding to avoid bleeding. They also cause texture streaming to be more inefficient. Only use atlases if you can save a lot of draw calls by using them.
