Break open an EXE file?

I have a sony Vaio and I have downloaded the sound driver for it. The driver claims it is being installed on a computer its not compatible with, and crashes. I know that it is wrong. I assume the driver files live inside the EXE, so I could just install them manually through the device manager if I could get the files out.

Does anybody know of a good program for popping open EXE files and extracting the contents?

A way to extract layer sets from PSD files without Photoshop?

Are there any tools for (in order of preference) Mac, Linux, or Windows to extract images per layer set from a PSD file, without using Photoshop? I had a web designer send me a PSD file containing multiple pages, and each page is apparently in a layer set, and GIMP cannot handle these -- it can't understand layer groupings.

A command line tool, a rinky-dink Windows tool...anything will work (of course, free is preferable), so long as it does not leave watermarks or anything of the sort, and works well.

How to get the .ico file of an arbitrary file?

Say I have a file and there is set an icon to it. How to get the icon which is figured on the file? File is an arbitrary - some extension about which I have no idea. Just how to get its icon.

EDIT: BTW the icon which is figured on the file is assigned when I told to SO open the file with an exe file I have created. And in that exe file there is no the icon that is on the file. Just, I guess, OS (Vista) have crated the icon of the file by takeing the icon of exe file and bu "putting" that on a white paper. SO I want to get this icon.

How to extract text with OCR from a PDF on Linux?

How do I extract text from a PDF that wasn't built with an index? It's all text, but I can't search or select anything. I'm running Kubuntu, and Okular doesn't have this feature.

Extract 7z files with standard linux tools?

I know that you can extract .7z files with 7-zip.

Is there another standard linux program that can do this? Maybe one of these

tar
bzip2
xz
gzip

I will add that bsdtar can do this, but is not available on all systems.

How can I extract multipart RAR files using the command line unrar.exe?

Is there a way to extract all RAR files using unrar.exe via the command line without passing it each part?

I have lots of multipart RAR files in mixed formats: .part1.rar, .part2.rar or .rar, .r00, .r01, etc.

Is there a trick I'm missing or this is something only possible from WinRAR (where you just right click Extract and it knows to extract from the other parts as well)?

In place extract tar archive

I have a little dilemma here...

I needed to move about 70 GB worth of files from one of my servers to the other, so I decided that tarring them up and sending the archive would be the fastest way.

However, the receiving server only has 5 GB of space left after receiving the tar archive.

Is there some way I can extract the tar 'in-place'? I don't need to keep the archive after it has been extracted, so I was wondering if it is possible to do this.

Edit: It should be noted that the archive has already been sent, and I'd like to avoid resending via a different method.

Extracting "one of every 10 frames" in a video using VLC or FFmpeg

I am trying to extract "exactly 1 frame of every 10" frames of a video (i.e. extract 1 , leave 9 then repeat) for scientific purposes. The video is 105 frames, 3.5 seconds, 29.97fps (h.264, .mov, produced by Nikon D3100).

I have uploaded it here.

VLC

Below command should produce 10 frames, but it only produces 6 images. I tried different scene ratios and neither of them produce correct number of frames (not even near to correct).

vlc 1.mov --video-filter=scene --vout=dummy --scene-ratio=10 --scene-prefix=img- --scene-path=. vlc://quit

Would someone please tell me what is the problem?

FFmpeg

FFmpeg does not seem to have a command exactly for my purpose. Below command extracts 3 frames out of every second, but since the FPS is not exactly 30 (rather 2.97), that will not produce correct results for me.

In addition even FFmpeg does not give out correct number of frames with even this command. For 3.5 seconds of video I expect at most 10 frames, but what I get is 12 frames!

ffmpeg -i 1.mov -y -an -sameq  -r 3 -f image2 -vcodec mjpeg %03d.jpg 

How can I achieve what I want?

Extracting background images from a PDF file?

I have a PDF file containing maps of the building I work in, here:

http://www.libsys.und.edu/dev/FloorPlans_All.pdf

The original source files have been lost, and I've been asked to extract the map images, preferably without the text and icons that have been overlaid on top of them. This has proven annoyingly difficult.

So far, I have tried the following GUI programs:

  • Adobe Reader: lets me select text, but not the background images
  • FoxIt PDF Viewer: lets me select text, but not the background images
  • XPDF on Ubuntu 10.10: lets mes select text, but not the background images

And also the following command-line programs:

  • pdfimages: extracts the icons indicating bathrooms just fine, but not the background images
  • pdftohtml: same as pdfimages, plus it makes a poorly marked up HTML document
  • pdfextract: same as pdfimages
  • convert: successfully saved images, but with the text burned into them

I've even tried opening the PDF manually in a text editor and extracting the stream objects by pasting them into a new file and saving it with a .jpg, .png, or .bmp extension (each in turn). Considering how little I know about the internal structure of PDF files, it's no surprise that this didn't work.

So ... is there any way I can retrieve the map images from this thing without also getting the text and icons?
