When creating a new archive, first choose TAR from "Save as Type". While adding files to that archive, choose "GZIPTar" or "BZIPTar" from the compression drop-down in the Options tab.

To extract a plain tar archive, you type tar -xf filename.tar. To extract a gzip (.gz) compressed tar archive, tar -xzf filename.tar.gz. Under Windows, you usually use ZIP (PKZip, WinZip) for making archives of files. Under Linux, there are two programs for this task. One program, called tar, is responsible for packing multiple files together into one file. It doesn???t do anything else, not even compression. For this you use a second program, usually gzip or bzip2.

See the Signature section at the bottom of this page: General Information As of 0.6.13, this is no longer true Digest fingerprints are listed with the download information at http://www.transcoding.org/. Pre-built packages of some distributions are not complete. This is a general problem. If you want to use the mpeg2enc export module, you will have to compile transcode yourself, or try to find a complete rpm on the net. (ems)

For simplicity, where a binary release is specifically intended for Windows, I have packed it as a .zip archive. They should expand under most decompression programs, including WinZip whose code is now, I believe, integrated into the WindowsXP system. Other archives have been packed as .tar.gz archives, for maximum portability between platforms.

In general, text files (.txt) can be compressed to 1/3 of their original size; while execution files (.exe) can be compressed to 1/2 of their original size.

I understand that PentaZip supports compression of MP3 files, but when I have zipped these it seems to make little difference to file size : e.g.: 2895620 byte reduced to 2878198 byte. Please can you advise if this sounds correct.

No, this message is only a warning and can safely be ignored - assuming it is the only error message.

A#1.7: The "core" files of the GNO distribution (such as the GNO kernel and gsh(1)) are available through anonymous ftp as described in Q#1.5. Non-commercial files, unless otherwise specified, should be available from major Apple ftp sites. There is often a GNO- specific directory, but compatible programs, patches, etc, may appear anywhere under the Apple II hierarchy. The GNO distribution also contains many files in this category; ensure you have newest versions by checking the ftp sites.

I am currently investigating this. It does work on most systems, but there are cases where it doesn't. If you have more detailled info about the cause or when this happens, please tell me.

For those that are really short on disk space, you can compress the help files and still be able to view them with Vim. This example assumes you have gzip on your system. You do have it, don't you? :-) If not, you will need to adapt it to work with a different compression utility. 1. Compress all the help files: gzip doc/*.txt. 2. Edit doc/vim_tags (doc/tags in 5.0) and do :%s=\.txt<Tab>/=.txt.gz<Tab>/= 3. Add these lines to your .vimrc: set helpfile=<dirname>/vim_help.txt.

The compression ratio of your files depends upon their content, however most documents are compressed to 25-50% of their original size.

Some types of files can be compressed much more than others. For example, *.txt and *.bmp files can be generally compressed by up to 96%. Various multimedia files (e.g. *.gif, *.jpg, *.wma, *.mpg files) are already highly compressed because the standards for these file types specify efficient technique to compress the content. Once a file has been compressed, it typically cannot be compressed again to any significant extent.

No. They are absolutely identical, byte for byte, to their pre-compression state. Even the file date and times remain the same.

Compressed or archived files (*.tar, *.zip, *.tgz) may contain many separate files in one large archive. Before all the separate files and programs can be read or run, an archiving program must be used to extract the files from the archive. More from IU Knowledge Base The IN DRGs are stored as compressed "*.tgz" archive files. Each archive is comprised of several files which are combined with the "tar" command and compressed using the GNU "gzip" utility.

To create a zipped compressed folder: Open My Computer. Double-click a drive or folder. On the File menu, point to New, and then click Compressed (zipped) Folder. Type a name for the new folder, and then press ENTER. Note: You can also create a zipped compressed folder by right-clicking the desktop, pointing to New, and then clicking Compressed (zipped) Folder. To extract files from a zipped compressed folder: Open My Computer and then locate the compressed folder.

Yes! NEOS does not allow you to compress your entire submission, but if you want to compress the files individually (to accommodate large data files, for example), you can submit them via the Web or Submission Tool interfaces. The NEOS Server checks each file to see whether it is compressed, so you can compress any data for which the interface has a Browse option. The compression types the Server supports are standard deflation for .gz,.z,.zip, and .Z files.

Since the AVI format does not have a universal standard, it can use different compression methods ? some of which cannot be processed into MPEG. This is true not only with "honestech MPEG Encoder" but also with most of other MPEG encoder products. Therefore, if the file is not in a generally used AVI format, it might be impossible to convert it to MPEG. Note: If you encounter the message "input avi audio must be uncompressed PCM!" , it means that the AVI file should not contain compressed audio.

Due to the site's business model, that is not possible. The subscription structure is based in part on space requirements. The more space bought, the more the subscriber is charged. Since allowing compressed files would defeat the purpose of charging Subscribers for the space they are using, we regret that we do not allow the use of any compressed files.

Less provides a mechanism to preprocess the file being viewed. The preprocessing can decompress a compressed file, or do other arbitrary processing on the file contents. However, each user must specify their own preprocessor. See the INPUT PREPROCESSOR section of the man page for more details. Less does not provide any default preprocessing, because the types of compressed files likely to be viewed depends on the work habits of the particular user.

You will need to unzip the zip file to get to the files within it. To do this, double click on the zip file. Select "extract files". You will be prompted for a location to store the files. Once they are unzipped, you have access to each individual file. Note: In order to do the above, you will need a program that unzips zipped files. pkzip/pkunzip is one such program and is free to download and install on your hard drive. To get the Windows version click here. For the DOS version click here.

The BXML format and the CWXML library are aimed at optimizing parser time and not compressed-document size. In fact, CubeWerx results show that the compressed file is usually around the same size for both XML and BXML. The only files that are significantly smaller are dense-numeric ones that are written properly, since GZIP is particularly bad at compressing dense numerics. However, one thing to note is that a BXML file is about half the size of the XML file (give or take) before compression.

Yes. You will have the capability to backup data to writable CDs and/or DVDs with your laptop. Rose-Hulman can provide procedures for backing up your files. Details are available at the Technical Services Center Help Desk.

For security reasons, you can only upload images and other selected file types. MediaWiki isn't oriented particularly towards uploading files other than image files, see: http://meta.wikimedia.org/wiki/Help:Images_and_other_uploaded_files. We have enabled uploading of .pdf and (perhaps?) tar.gz files. Try it, and if it does not work, send us a message.

These are gzip-compressed tar archives. If you have the GNU tar utility (included in all GNU/Linux distributions and many other versions of Unix including Mac OS X (Darwin), and available for MS-Windows as part of the free Cygwin software development package), you can unpack foo.tar.gz in one step: tar xfvz foo.tar.gz If you have another version of tar, it may not support the z option, and you may need to decompress using gzip before unpacking, like this: gzip -d foo.tar.gz tar xfv foo.

If the archive link at the top of the page does not work, try this Archives Link Those last numbers before the html tell you what number of board you are on. If you change that number to the one below it you will go to yesterday's board.

We've put together this reference table to illustrate the amount of space a streamed video takes up on a server. Keep in mind that many factors such as the data rate, the length of video, and the image size can affect the overall size of the files and these numbers are meant for comparison only. The following table, with the exception of full DV, is for Quicktime (.mov) video using the Sorenson compression format (web streaming standard).

Files are encrypted and compressed on the server in a process that is completely transparent to users. In future versions of the desktop clients, files and content will be encrypted on the client prior to being sent to the server. This ensures a high level of security. All communication with the server is over a secure and encrypted connection. Some beta users currently only have normal HTTP, but we will be moving all of your accounts over shortly.
