May 20, 2019 The WarnFileSize registry entry determines the maximum data that both the.pst and the.ost files can have. After this maximum data is reached, neither the.pst nor the.ost files are permitted to add any more data. However, the size of the physical file may still increase because of. You're reading the entire file into memory (line = u.readlines) which will fail of course if the file is too large (and you say that some are up to 20 GB), so that's your problem right there.Better iterate over each line: for currentline in u: dosomethingwith(currentline) is the recommended approach.

Apple Disk Image is a disk image format commonly used by the macOS operating system. When opened, an Apple Disk Image is mounted as a volume within the Macintosh Finder.
An Apple Disk Image can be structured according to one of several proprietary disk image formats, including the Universal Disk Image Format (UDIF) and the New Disk Image Format (NDIF). An Apple disk image file's name usually has '.dmg' as its extension.
Features[edit]
Apple Disk Image files are published with a MIME type of application/x-apple-diskimage.
Different file systems can be contained inside these disk images, and there is also support for creating hybrid optical media images that contain multiple file systems.[1] Some of the file systems supported include Hierarchical File System (HFS), HFS Plus, File Allocation Table (FAT), ISO9660 and Universal Disk Format (UDF).[1][2]
Apple Disk Images can be created using utilities bundled with Mac OS X, specifically Disk Copy in Mac OS X v10.2 and earlier and Disk Utility in Mac OS X v10.3 and later. These utilities can also use Apple disk image files as images for burning CDs and DVDs. Disk image files may also be managed via the command line interface using the hdiutil utility.[3]
In Mac OS X v10.2.3, Apple introduced Compressed Disk Images[4] and Internet-Enabled Disk Images for use with the Apple utility Disk Copy, which was later integrated into Disk Utility in 10.3. The Disk Copy application had the ability to display a multi-lingual software license agreement before mounting a disk image. The image will not be mounted unless the user indicates agreement with the license.[5]
An Apple Disk Image allows secure password protection as well as file compression, and hence serves both security and file distribution functions; such a disk image is most commonly used to distribute software over the Internet.
History[edit]
Apple originally created its disk image formats because the resource fork used by Mac applications could not easily be transferred over mixed networks such as those that make up the Internet. Even as the use of resource forks declined with Mac OS X, disk images remained the standard software distribution format. Disk images allow the distributor to control the Finder's presentation of the window, which is commonly used to instruct the user to copy the application to the correct folder.
A previous version of the format, intended only for floppy disk images, is usually referred to as 'Disk Copy 4.2' format, after the version of the Disk Copy utility that was used to handle these images.[1] A similar format that supported compression of floppy disk images is called DART.[1][6]
New Disk Image Format (NDIF) was the previous default disk image format in Mac OS 9,[1] and disk images with this format generally have a .img (not to be confused with raw .img disk image files) or .smi file extension. Files with the .smi extension are actually applications that mount an embedded disk image, thus a 'Self Mounting Image', and are intended only for Mac OS 9 and earlier.[7][2]
Universal Disk Image Format (UDIF) is the native disk image format for Mac OS X. Disk images in this format typically have a .dmg extension.[1]
File format[edit]
Apple has not released any documentation on the format, but attempts to reverse engineer parts of the format have been successful. The encrypted layer was reverse engineered in an implementation called VileFault[8] (a spoonerism of FileVault).
Apple disk image files are essentially raw disk images (i.e. contain block data) with some added metadata, optionally with one or two layers applied that provide compression and encryption. In hdiutil these layers are called CUDIFEncoding and CEncryptedEncoding.[1]
UDIF supports ADC (an old proprietary compression format by Apple), zlib, bzip2 (as of Mac OS X v10.4), and LZFSE (as of Mac OS X v10.11)[9] compression internally.

The trailer can be described using the following C structure.[10] All values are big-endian (PowerPC byte ordering)

Utilities[edit]
There are few options available to extract files or mount the proprietary Apple Disk Image format. Some cross-platform conversion utilities are:

In Windows, most dmg images can be opened using several other programs such as UltraISO and IsoBuster. MacDrive can also mount simple dmg files as drives under windows, but not sparse disk or encrypted dmgs.[13] A free Apple DMG Disk Image Viewer also exists.[14]
In Linux and possibly other Unix flavors, most .dmg files can be burned to CD/DVD using any CD-burner program (using cdrecord directly or a front-end such as K3B or Brasero) or directly mounted to a mountpoint (e.g.
mount -o loop,ro -t hfsplus imagefile.dmg /mnt/mountpoint ).[15][16] darling-dmg is a FUSE module enabling easy DMG file mounting on Linux.[17]

Apple has always been creative in dealing with the marketing strategies that they come up with to make a stand in the market. the release of the Mac OS X snow leopard is by far considered the best market release. This statement is adhered to by the low price release the end-users had to pay for a single user license as well as the ease of involvement involved with the use of the Mac OS X snow leopard.
The Mac OS X snow leopard didn’t house any new additional feature but was hauled with an improvement in the software framework the existing features worked on. The Snow leopard was introduced into the market for a very low price od 29$ that made the OS be downloaded almost b every end-user of a Mac.

Apple Inc. Overview
The Mac OS X snow leopard can be considered as the trial experiment held by apple to make an improvement in their software framework and also increase the credibility of the devices offered by Apple to the market. Apple majorly focused on the software part with this OS update merely to experiment with new software algorithms and expand the technological horizon of the operating system.
The changes made to the existing features will give you a brief idea about how Apple planned to revolutionize computing.
Mac App store
The full-scale dedicated store to download all the applications for your Macintosh system. This was released along with the Mac OS X leopard to get the response from the end-user about its practicality and when all positive reviews turned in, apple decided to go with the MacApp store with a tweak to the software frame and also improving the user interface between the user and the system.
Lesser space
Apple was very particular about reducing the amount of memory taken up by the operating system. Since the Mac OS X Snow leopard was an overhaul feature improvement update, Apple planned to keep things subtle and succeeded in keeping the bar less than 7GB compared to its ancestor the Mac OS X leopard. They mainly cut down on the space that was used up for pre-installed drivers for printers.
User Interface tweaks
Apple also made an intelligent watch over the aesthetic details that accompanied with the update. They made sure that they made the user interface as interactive and compelling as possible to give the user a good experience while using the system. they also made sure that the tweak in the traffic light type buttons on the title bar is kept subtle and lighter to give a jump to the aesthetic detailing.
The finder application was also fully revamped from scratch and was written in Cocoa, Apple’s very own objective-oriented programming language. This gave Apple the chance to upgrade their usage as well as get the most out of cocoa as well.
The sleep and boot rate of the Mac OS X snow leopard is considered to be the best and fast in its class.
Architecture transformation
With the Mac OS X Snow leopard, the 32-bit architecture went into the dark in the history of constructing architecture for apple devices. This ensures that apple devices only worked on 64-bit resolutions. This meant that the previous apple device which could only support 32-bit were starting to rot as scrap. This move from Apple wasn’t welcome by many but as the popularity of the 64-bit architecture spread, apple sufficed through the rough patch.
Open CL
The Open Computing Language or popularly known as the Open CL is considered as the language that paved the way for improvement in the graphical user interface of the Apple devices. The precision involved in numerical processing made by the open CL ensures that the optimal use of the graphical interface was done. This also ensured that the proper load of work was put on the GPU and enabled to adapt the screen to 3-D games like a pro. The open CL is based on the open standard format that was supported by all the leading graphical processing chips of famous brand names like AMD, Intel, Nvidia, etc.
