The answer is "it depends". Depends on what you mean by "download". If you're downloading from a web site, than some sites automatically compress files "on the fly", and text compresses very well, while JPEG is already compressed, so it won't compress at all. In this case, there will be a big difference. If you're just using a copy command to copy files ...

Use: find . -type f -size +4096c to find files bigger than 4096 bytes. And : find . -type f -size -4096c to find files smaller than 4096 bytes. Notice the + and - difference after the size switch. The -size switch explained: -size n[cwbkMG] File uses n units of space. The following suffixes can be used: `b' for 512-byte blocks (this is ...

Windows has lots of legacy code for backwards compatibility with heaps of third-party vendor software and platforms. It also includes full third-party drivers for heaps of software. Windows software in general has a history and reputation for being bloated, which is largely due to compatibility reasons. Windows also has the capability to play a variety of ...

From my answer originally at Server Fault Question 7237: When a monitor is unplugged (including the adapter as well if applicable - leaving the adapter leaves OS X thinking the monitor is still plugged in) all the Windows should move onto your main screen. Occasionally some windows (eg. Firefox) will keep their position on the very far right of the screen ...

du -s directory, as in "disk usage, sum" Use du -sk to show the size in kilobytes (default is to show number of 512-byte blocks), or du -sh for a more human-friendly output. For more options, type man du.

With 5GB of pictures you are likely to be talking about a few thousand reasonably sized files, say 3MB+ each. If you were download 5GB of text files, you'd typically expect each file to be a lot smaller. So you'd likely be dealing with an order of magnitude or two extra files (hundreds of thousands or millions of files). Copying lots of small files takes ...

Most of these will only help with existing documents, but saving as the Word 2007 DOCX format will help with new documents. Word 2007 Compress Images Click on an image Go to the Picture Tools "Format" ribbon Click "Compress Pictures" There are then various options for deleting cropped areas, lowering the resolution etc. Save as DOCX The new DOCX ...

You should use tmpfs for that instead. mount -t tmpfs -o size=10g none /mnt/point

The "It Depends" in ftp is in the fine details. ftp Binary mode just a straight transfer and will take the time it takes for 5GB. If you're going from Windows to Linux as an ftp text transfer (for surprisingly, plain text), ftp actually changes the line endings from /r/n to /n and vice-versa. There's probably a little overhead in the streaming replace, ...

That really isn't the purpose of Notepad++. While a print preview function might be a good feature, Notepad++ is geared more toward helping keep code organized, differentiating files, etc. If you want to see how many pages it is before hand, try printing to PDF first. At least then you have a digital version and are able to see how many pages it is. I ...

SpaceMonger isn't bad (referring to Barden's suggestion), but I also like WinDirStat. It's OpenSource. I even use it on my servers. It can scan network drives too and gives a nice graphical output that shows files as multicolored blocks. Take a look at the site for screenshots.

Will I experience the benefits of 7200 rpm over 5400 or will SATA2 limit the speeds below the capabilities of the drive? The SATA-II (3.0 Gbit/sec) interface tops out around 270MB per second. Top speed for current average consumer harddrives is about half that. Top speed of 15000 RPM SAS enterprise drives is nearly 200 MB/sec. Still way below ...

Based on my first-hand experience developing firmware for disk controllers, here's an answer from a different perspective. You question seems to based on a misconception that, somehow, R/W_head-to-platter transfer rates affect the drive-to-host transfer rate. The reality is that these two I/O transfers are separate operations, and do not interact on any ...

Although the tmpfs answer would usually work (thanks Ignacio), however, in my unique case I was looking for something a little bit more specific. I found information about how to configure ramdisks from this link Linux Ramdisk mini-HOWTO unfortunately, this link is broken, but if you google the url, you can view google's cached version of the page. Also I ...

The full install of MikTeX includes loads of add-on packages, most of which you will never use, plus loads of fonts for lots of different alphabets. Rather than install it all, it is better to do a minimal install and allow MikTeX to install required packages and fonts on the fly (assuming you have an internet connection when you are using it). The ...

MP4 and FLV are just container formats. The size of the container depends on the content within it, which can use an arbitrary compression format (depending on the compression format supported by the MP4 and FLV containers). You need to compare the compression format of the file, not the container. Even if you were to compare the relative compression ...

ImageMagick (Windows/Mac/Linux) contains a command-line tool called convert that can be used for many things, including packing multiple images in one icon: convert 16.png 32.png 48.png 128.png 256.png -colors 256 icon.ico The previous command takes 5 PNG images, and combines them into a single .ico file. Unlike the other answers, this method can easily ...

It's actually configurable by registry. The default size limit is 2GB for Outlook 2003. If you are using the Large File Format, the limit is 20 GB. For more information about configuring it, read here.

Considering you have several hundred metres (or maybe several Km) of phone wiring + joints & cabinets between your socket and the local exchange/CO, a few more metres is not generally going to make a significant difference. That said, some extension leads and reels use very poor quality cable that can really mess up broadband signals due mainly to the ...

My question is: would my connection be significantly faster if I moved the modem and used a short, high-quality phone cable between the modem and the wall? It's not easy to answer. Yes, probably. Note that your question uses the words "significantly faster". This is what I cannot tell you. This could only be answered after testing because it depends ...

Try the Disk Usage utility from Sysinternals. Specifically, du -l 1 should show the size of each subdirectory of the current directory. For more information, run du without any parameters. If PowerShell is OK, then try the following: Get-ChildItem | Where-Object { $_.PSIsContainer } | ForEach-Object { $_.Name + ": " + ( Get-ChildItem $_ -Recurse | ...

An uncompressed backup of 500 GB will take 500 GB (± file system differences). A compressed backup will take less. How much, you ask? This depends on the compressibility of the files contained. If these are movies or images, they are already compressed. Most text files on the other hand are not. To demonstrate how much the compression ratio can vary, here ...

Generally the size of the databus is determined by the the size of the processor registers. Often it is the size of the processor registers that determine the OS type (64 vs 32). The physical bus sizes can technically differ from this (8088 as an example) but it's so rare that the author of your quote probably associates the two together. Generally the ...

find . -type f -size -10485760 -ls run in your current directory or you can do find /etc/home/user/stuff -type f -size -10485760 -ls using a path so, my format is basically find path of -type f (file) with -size of less than (-)10485760(10MB in B) and -ls to make it pretty for you. Per Dennis' suggestion adding -maxdepth 1 would prevent recursing into ...

(Upfront caveat: this isn't a perfect answer to your question, but it seemed useful/interesting enough to share.) If you save the following text to a file with an extension of .bat or .cmd (e.g. runconditional.cmd): @echo off if %~z1 LSS 1048576 ( notepad.exe %1 ) else ( c:\my\path\to\notepad++.exe %1 ) ...then you should be able to use it to ...

Actually, it is possible to do this, with a little trickery. You need to edit the Finder's preference file to turn on the options that the View Options panel's disabled buttons equate to. To accomplish this, you need to edit the com.apple.finder.plist preferences file which should be located in the following folder: /Users/~/Library/Preferences/ I use ...
