Fork (filesystem) - Wikipedia, the free encyclopedia Filesystem forks are traditionally associated with Apple's Hierarchical File System (HFS), however they are also available in Microsoft's NTFS filesystem, where they are known as alternate data streams. HFS was designed to allow a file to have a resource fork to store metadata about a file that would be used by the graphical user interface (GUI) of the Apple Macintosh, such as a file icon or an image preview. You can have data loss when sending files via fork unaware channels (e-mail, filesystems without multiple forks support -or even when copying between filesystems with forks support, if the program that made the copy is unaware-, compressed archives) and not be aware of that. en.wikipedia.org /wiki/Fork_(filesystem)   (727 words)

Resource fork - Wikipedia, the free encyclopedia The resource fork is a construct of the Mac OS operating system used to store structured data in a file, alongside unstructured data stored within the data fork. The resource fork is sometimes used to store the metadata of a file, although it can also be used for storing the actual data, as was the case with font files in the classic Mac operating systems. In addition, a file server seeking to present filesystems to Macintosh clients must accommodate the resource fork as well as the data fork of files; UNIX servers usually implement this with hidden directories. en.wikipedia.org /wiki/Resource_fork   (1609 words)

Mac OS - Wikipedia, the free encyclopedia The data fork contained the same sort of information as other file systems, such as the text of a document or the bitmaps of an image file. The resource fork contained other structured data such as menu definitions, graphics, sounds, or code segments. A text file could contain its text in the data fork and styling information in the resource fork, so that an application which didn't recognize the styling information could still read the raw text. en.wikipedia.org /wiki/Mac_OS   (2836 words)

MacKiDo/Innovation/FileForks The resource fork is a way to have all of the common elements (strings, icons, sounds, pictures, and so on) in a separate database/fork separate from the programs data. It is because of the resource fork that it is much easier to "localize" programs for different countries, and it is easier to fix and edit the interface (or many interface elements) separate from the rest of the code. NTFS's forks are nicer in that they actually allow many forks -- Macs original MFS and HFS only allowed for a resource and a data fork, though Apple had been talking about adding multiple named forks for years before NT. www.mackido.com /Innovation/FileForks.html   (1276 words)

Mac file -- Resource and data forks The information to be stored in the resource fork has to be in some special structure that is suitable for the resource fork, and does not need to be changed so often. For example, user data, which get changed frequently and are usually long, and of variable length, are stored in the data fork. A HyperCard stack file is an instant of those user files that utilize both of its forks: the text of the text fields are stored in the data fork, and the new icons, cursors, and sounds are stored in the resource fork. www.cse.yorku.ca /Courses95-96/4361/q15.html   (1175 words)

MAC OS data recovery service Whether using a PC or a Mac, for business or pleasure, valuable data should be protected from impending harm caused by viruses, hackers, power surges, human error, natural disasters and more. The data fork can hold any type of data (text, images, etc.) and does not have a required a structure like the resource fork. Mac resource forks are generally of no use on the PC, but it is possible for a PC program to convert specific resources to a PC format. www.dtidata.com /mac_data_recovery.htm   (583 words)

ResFool User Manual Preliminary Documentation This document contains preliminary documentation for the ResFool ... Internally, all the same data typically stored in the resource fork of a file is instead stored in the data fork of the file. Since the data fork is being used for the resource data, these files have no "data" other than the resources stored in it. Data may be aligned on two or four byte boundaries, or some other arbitrary number of bytes. www.ljug.com /sw/docs/resfoolmanual.html   (6235 words)

Macintosh File Forks The data fork contains what we generally call a file on the PC, that is the text created by a word processor, the pixels building a picture, etc. When transferring data files between Macintosh and PC, the data fork is generally the only part of interest (the major exception is font files, see below). Against what is often said, even by knowledgeable persons, the resource fork doesn't contain the signature of Macintosh files (file type and file creator), which is stored in the disk catalog. The resource fork is organised as a data base, which allows for a fast access to all components of the stream. www.macdisk.com /macforken.php3   (637 words)

How to Join Data and Resource Forks Using UnErase The data fork is the portion of the file that holds the data, and thus is the most important part of the file. Data forks are recovered with generic names (for example, "Quicken 5.0/6.0/7.0 #614"), which can make files difficult to identify. You will find many resource forks with no data forks adjacent to them; in most cases, you do not need to recover these, as they are not likely to contain data that you have created. service1.symantec.com /SUPPORT/num.nsf/docid/1998102313415311   (630 words)

TMDL Case Study - West Fork of Clear Creek Basinwide monitoring data collected by both of the mines to fulfill their permit requirements led EPA to conclude that implementation of the WLAs alone would not attain all applicable water quality standards (WQSs) for Woods Creek and the West Fork. Since ample monitoring data were available for Woods Creek and the West Fork, and the data seemed sufficient to support determination of a TMDL that would meet water quality standards, a one-time calculation of the TMDL was planned and executed. The West Fork data base is considered to have a fair period of record, broad spatial coverage within the subwatershed, and relatively good consistency in sampling and analytical methods since most of the data used to develop the TMDLs were collected by the dischargers. www.epa.gov /OWOW/TMDL/cs3/cs3.htm   (3213 words)

[No title] The Data fork is typically the only meaningful part of a Macintosh file on a non-Macintosh computer system. Security Considerations To the extent that application/applefile facilitates the transmission of operating-system sensitive data, it may open a door for easier relaxation of security rules than is intended either by the sender of the administrator of the sender's system. The data fork is easily extended because it resides by itself in the AppleDouble Data file. www.ietf.org /rfc/rfc1740.txt   (2196 words)

Mac Geekery - Fork (and) You Forked files frequently fared fowl in file operations for a few reasons, the first of which is that only the Macintosh ever really utilized them. Forked files were the 1980s answer to the same question that spawned packages in Mac OSi X: How can we keep an application and its support data together so it doesn't require an installation? That is, don't try and force a whole set of files to be serialized into one binary store of a forked file, but, instead, leave the files be and just tell the OS to hide them. www.macgeekery.com /gspot/2006-05/fork_and_you   (752 words)

Data::MacResFile - Perl extension to read a Macintosh Resource fork Instead of a stream of bytes, data from a resource fork is retrieved in complete units when the operating system is given certain keys of information. This is less useful than the open_fromhandle constructor, because most files that have a combined data and resource fork specify the offset at another point in the file. The data is read from the file directly into a single scalar, no attempt at interpretation is done on the data. world.std.com /~aml/perl/macresfile/MacResFile.html   (672 words)

Formats Other operating systems don't support this (one could say their files consist only of a Data Fork), so every time you transfer a Macintosh file to a different OS you will lose the Finder Info and the Resource Fork for that file. This is what we call 'Binary transfer' (since gzip is a Unix compressor and gzip format holds compressed Unix data, to gzip a Macintosh file is analogous to transfer it to a Unix machine), so after the transfer you will get a file with exactly the contents of the Data Fork byte by byte. Earlier we said text is in the Data Fork (usually), so you may think it's enough to transfer it in binary mode. persephone.cps.unizar.es /~spd/gzip/File_Formats.html   (816 words)

Hidden Threat: Alternate Data Streams A relatively unknown compatibility feature of NTFS, ADS is the ability to fork file data into existing files without affecting their functionality, size, or display to traditional file browsing utilities like dir or Windows Explorer. Alternate Data Streams have come to be used legitimately by a variety of programs, including native Windows operating system to store file information such as attributes and temporary storage. Ultimately, the mere availability of Alternate Data Streams in NTFS is quite disconcerting and their usefulness suspect but in the end, the security features of NTFS far outweigh this potentially dangerous vulnerability. www.windowsecurity.com /articles/Alternate_Data_Streams.html   (1173 words)

Fork Oil Data - Mtbr.com Forums Not the normal fork operating temperature this time of year in the U.S. depending on where you are at, but it still seems consistant with what I have felt on many of these fork oils I have run in my fox fork. The Penzoil is in now way a fluid to ever use for a fork for damping, but it was for the heck of it to show how slow and thick it is compared to fork oils. What was noticeable was the amount of wallow the fork had with the lighter oils vs. the heavier oils had a more controlled feel, the bigger the successive hits the more the fork was bouncing off the line it was pointed towards using the lighter oils. forums.mtbr.com /showthread.php?t=68684   (3639 words)

Editors Data Sheet Every file's data fork is treated as if it were just another resource in the file. The data fork can be edited with Resorcerer's powerful Hex Editor, or you can parse the data with a template and edit it more easily with the Data Editor. Resources (in the form of the resource fork data format) on Mac OS X can now be stored in the data fork of a file. www.mathemaesthetics.com /EdInfo.html   (1763 words)

How Macintosh QuickBASIC Uses Resource and Data Forks of Files Any file stored on a Macintosh disk has two parts or forks: a resource fork and a data fork. The data fork is often used for the contents of data files. The code for your program is located in the data fork in the disk files for compiled and interpreted programs. support.microsoft.com /kb/42463   (325 words)

Command Resources A resource is data of any kind stored in a defined format in a separate file or in the resource fork of a Macintosh file. Originally, on Macintosh, data and resources were stored in the same file, made of a data fork and a resource fork. The data fork of a Macintosh file is the equivalent of a file on Windows and UNIX. www.4d.com /docs/cmu/CMU10053.HTM   (1904 words)

kbAlertz: To preserve data in Macintosh file attachments, Outlook for Microsoft Windows searches a registry key to ... Macintosh files are multipart; they have a resource fork and a data fork. In keeping with this generally accepted practice, whenever Outlook for Windows determines that an attachment is of Macintosh origin it ignores the resource fork, which cannot be used, and stores the data fork in a single file stream. In the case where Outlook was unable to determine Macintosh compatibility and consequently stored an attachment's resource fork and data fork in a single file stream, the data fork that the Macintosh operating system creates includes the information from the resource fork. www.kbalertz.com /kb_Q251412.aspx   (1399 words)

Command BLOB TO DOCUMENT For example, the data fork of a 4D database is stored in a file with the file extension.4DB; the resource fork is stored in a file with the same name and the file extension.RSR. On Windows, if you write a 4D application with the data fork and resource fork stored in BLOBs, you just need to access the file corresponding to the fork with which you want to work. In a data entry form, you create a button which allows you to save a document that will contain the data previously loaded into a BLOB field. www.4d.com /docs/cmu/CMU00526.HTM   (310 words)

Water Quality - Roaring Fork Conservancy In 2001, the Conservancy published the first State of the River Report summarizing water quality data in the Roaring Fork Watershed from the previous year. Currently, we are working on a new report, which highlights potential problems on Cattle, Brush, and Four Mile Creeks. Data is collected by Valley students and teachers through River Watch, by Stream Team volunteers from the community, and by Conservancy staff. www.roaringfork.org /sitepages/pid19.php   (148 words)

Accessing data fork resources as a resource - The macosxhints Forums I know there is a notation that allows you to access a files resource fork as a data fork resource file, for example: To clarify my question, what I want to do is get MacForth to open a data fork resource file in such a way that it thinks its reading a file with a resource fork. Alternatively, use 'tar' to create an archive file from the file with the resource fork and put this tar file under source code control. forums.macosxhints.com /showthread.php?s=&threadid=56111   (555 words)

Services for Macintosh SFM Macintosh files use a data fork and a resource fork. The data fork contains the content of the file whereas the resource fork contains Macintosh OS info including icon, font, menu, and code. Mac print sharing can be installed on a FAT partition since only the data fork is the only fork used for printing. www.windowsnetworking.com /kbase/WindowsTips/WindowsNT/AdminTips/Services/ServicesforMacintoshSFM.html   (457 words)
