Talk:Disk compression

Non-DOS-based disk compression

This article currently gives only passing mention to filesystem compression on other operating systems. Much of the article (especially in the ‘How disk compression works’ subsections) is specific to MS-DOS / Windows implementations. This makes me unsure as to how to add information about implementations on other operating systems. Perhaps rename that section title to ‘... in MS-DOS implementations’.

Some relevant articles on Linux implementations include Cramfs, SquashFS, e2compr, zisofs, and block device compressors such as cloop, and possibly a mention of the related common practice of compressing an entire filesystem image when it is intended to be decompressed into a ramdisk or some other medium before being accessed. One could also add a link to executable compression.

Here is some brief information about them as I'm aware of (without checking too much):

cramfs, SquashFS, cloop and presumably zisofs[*1] are only for read-only filesystems.

[*1]: I guess that zisofs is readonly because it's an extension of the ISO 9660 filesystem that's used primarily for read-only media.

Such readonly filesystems are sometimes used in combination with a UnionFS implementation to provide a read-write filesystem. (Ref: SquashFS#Uses.)

Just create a new sub-section and add your contents. If we get enough information in the long run we could split out more specific stuff into separate articles and keep this article as a more general "shell" article. However, we'd first have to collect enough material to warrant more than one article. --Matthiaspaul (talk) 23:25, 5 April 2015 (UTC)

I'd like to add that almost all of the DOS-based on-the-fly disk compression schemes discussed are based on the idea of an optionally loadable driver implementing some kind of virtual or meta volume on top of the existing FAT file system driver. All the contents of this volume is stored in compressed form in a single file on the underlying native filesystem, which is not compressed. This is quite different from how "modern" disk compression works as integrated part of the file system itself. Therefore, when we add information about the newer solutions, we really should point out the differences and keep them in separate sections. --Matthiaspaul (talk) 11:05, 3 April 2019 (UTC)

ZipMagic

This page does not discuss any modern disk compression solutions:

• NTFS compression
• Windows 10 XPRESS/LZX compression
• WIMBoot compression

And as such falls substantially short of page target.

I am being repeatedly censored in my efforts to add this information to the page. — Preceding unsigned comment added by 78.187.192.54 (talk) 12:18, 5 September 2015 (UTC)

You are not being censored. Now that I've taken a look at the page history, I've noticed a swarm of IPs adding links to software called Zipmagic -- and that is the main issue. Other problems include MOS:HEAD, I also don't understand why you have added 'early' to a bunch of sections. ^{My name is}not^dave (talk/contribs) 12:24, 5 September 2015 (UTC)

As My name is not dave observed, the article has a history of people (both IP editors as well as registered accounts) adding content that ultimately constitutes promotional material for ZipMagic. Given the persistency of such edits, as well as the fact that the editors involved have resorted to sockpuppetry, it's very hard to see these edits as anything other than blatant spam, to which an immediate revert and talk page warning are the proper response.

It should be noted that the spam is not confined to this article; similar edits have been made to articles about the Microsoft Surface tablets (see the SPI link above for examples). Indrek (talk) 12:48, 5 September 2015 (UTC)

Revert

I have reverted 78.170.132.129 which was accepted by User:Rubbish_computer [[1]] as its outsourced and part is sourced using forums and promoting zipmagic products. I missed to put the edit summery Bentogoa (talk) 12:46, 26 September 2015 (UTC)

@Bentogoa: Sorry, I should have checked it more thoroughly. Thanks. --Rubbish computer 13:22, 26 September 2015 (UTC)
