Opening disk image files in Windows?

Is there anything, free software or something like MacDrive (which I've never used) that will open disk image files, particularly encypted ones? I keep an encrypted disk image on my thumb drive with important information and I'd like to be able to open it in Windows. I recently came across the open-source TrueCrypt for Linux and Windows, but I would love some kind of software that would work on all three platforms, or at least OS X and Windows.
Thanks,
Alan

Can't open disk image file

I saved my iDVD project as a disk image onto my hard drive. All of the encoding took place as if I were burning it to a DVD disk. After the encoding was finished, two icons popped up on my desktop: One with a .img extension, and one with a hard drive type image with only the project name and no extension. When I try to open either one of them, my project does not come up. The .img file is totally empty. The other file, the one named "my project name", has an Audio_TS folder which is empty and a Video-TS folder that contains six files, all of which require a "choose application" to open. I tried iDVD as an application, but that didn't work. How do I get my iDVD project to open so that I can burn a DVD disk from it? Right now, the two icons on my desktop are useless.

The other file, the one named "my project name", has an Audio_TS folder which is empty and a Video-TS folder that contains six files, all of which require a "choose application" to open.
This is the mounted disk image file and can be played with Apple's DVD Player application. BTW, the AUDIO_TS folder Should be empty - it's not used in video DVDs.

"Always Open In..." View Options for Root Level of a Disk Image File

I ran into a problem/bug tonight that I can't find listed anywhere and was wondering if anyone else has encountered it. I am using Snow Leopard (now 10.6.1), upgraded from the last revision of Leopard.
I create DVD-R sized disk images with Disk Utility (using "Mac OS Extended" only w/o Journaling) for saving downloaded files. Because of the number of files on this disk, I create single-letter folders (for alphabetical filing) and set up these disk images to "Always Open In List View". For the individual folders, I can set these to "Always Open In List View" without a problem. However, for the "root level" of these disk images, I can only access "Always Open In Icon View" no matter which view option is selected.
For previously created disk images that were already set to "Always Open In List View", these show the previously set "List View" at the disk image "root level" as expected. But if I uncheck the box, it immediately goes to "Always Open In Icon View". And like before, no matter which view option is selected, I can never get back to "Always Open In List View". Note also that I can set this option as expected for "root levels" of real disks - this only seems to be a problem with the disk image files.
I had no problems at all with this under Tiger or Leopard. I've only run into this now under Snow Leopard. The upgrade tonight to 10.6.1 hasn't seem to affect this problem.
So should I be doing something differently now to get this option to reappear, a possible conflict with something on my computer or is this a bug with Snow Leopard? Can anyone else duplicate this issue?

Additional info, in case anyone is running into this issue...
If I do the following with the "root level" of the disk image, I can set the "Always Open in List View" option.
1. Open the "root level" view of the disk image - for me, it always opens in icon view. Then, select "Show View Options" from the View menu.
2. Check the "Always Open in Icon View" box. While leaving this dialog open, select "as List" from the View menu.
3. Uncheck the "Always Open in Icon View" box. It will instantly turn into "Always Open In List View". Recheck this box immediately, then close dialog. This will make the setting stick.
I've been able to repeat this situation several times. I might be wrong, but it sure acts like a small bug to me. Hope this helps anyone else who might have encountered this issue.

Drag image file from Windows Explorer to a new layer in an open file

I want to know if it's possible in CS3 to drag an image file from Windows Explorer into an already open file in PS. Right now when I drag over, it opens that file. I want to have it where the image is inserted as a new layer into the existing open file. is that possible?

Hi, I'm using CS4 and would love to be able to drag n drop straight to a new layer in an existing file.
At present when I drag n drop I get a new image in PS. I then have to move this to my existing image. I have tried draging to the tab, the layer box, the image, the blank space, using shift,ctrl & alt.
A simple how to would be nice

Windows Disk-Image File: What to Exclude from Time Machine?

I don't use Parallels very often, but when I do, the famous, predictable annoyance comes up: The Windows disk-image file under MacOS gets tweaked, and then suddenly Time Machine has this mondo-huge 25GB file to backup. That of course, clogs up my Time Machine backup drive.
A common solution appears to be to exclude that file from Time Machine, and then back it up by some other means. OK, I'm cool with that, if only I knew what that file is called, and where I could find it, so that I can tell Time Machine to exclude it.
I'm guessing it's somewhere down in System or System Folder?

Ask on the Parallels forums, as its their software you have questions about

Preview 4.1 - "open all images in one window"

Dear users,
Despite checking this button in Preferences, Preview often (not always) will open my images in different windows, as opposed to in one window with a thumbnail pane. This is especially true across file formats. Am I doing something wrong? THANKS!!

First, put enough images into /Users/Shared to test. Then, create a new account, name it "test" and see how your Preview app works in that User acct? (That will tell if your problem is systemwide or limited to your User acct.) This account is just for test, do nothing further with it.
Open System Preferences >> Accounts >> "+" make it an admin account.
If the problem is present in the test account also, then it is systemwide. In this case try repairing this with the 10.5.4 Combo Update . This is a fuller install, as opposed to an incremental "delta" update so it should overwrite any files that are damaged or missing. It does not matter if you have applied it before.
Remember to Verify Disk before update and repair permissions after update from /Applications/Utilities/Disk Utility.
If the problem does not appear in the test account try starting in "Safe Mode" (It will take a bit more time to startup because it runs a directory check first).
If that works go to System Preferences >> Accounts >> Login Items and remove them. Boot normally and test. If there are still problems, go to ~(yourHome)/Library/Contextual Menu Items and move whatever is there to the desktop. Then do the same with /Library/Contextual Menu Items. Lastly, try moving /Users/Home)/Library/Fonts to your desktop and restarting.
Log out/in or restart, if that sorts it start putting items back one at a time until you find the culprit.
Let us know.

Disk-image files- file size

I have created a disk-image file on my backup hard drive to save important data. This has 2 folders of around 180mB. I am now trying to save more files and the message comes up that there is not enough free space to copy the file. Do these disk-images have a certain size and how can I determine this. Is there an option to create bigger image file sizes. I would ideally like to create disk-image files up to 4 gB and then burn to DVD for backup.

Welcome to the Forums!
Yes, disk images have the size specified when they are created. You can't increase it, you need to create a new, larger disk image and copy the files to that.
You can see the size by selecting the disk image then File menu > Get Info, or by mounting the disk image, opening it and looking at the bottom of the window.
Use Applications > Utilities > Disk Utility to create a new disk image. There's a default choice for 4.7 GB (the capacity of a DVD).
Hope this helps...

How do I do a backup using a disk image file and SuperDuper?

The external drive won't mount on the desktop even though the power light shows up on the external drive case. I want to back up the files on the computer, Powerbook G4 Panther in a hurry as the computer keeps shutting down on me.
I opened up SuperDuper which I normally use for backups and there was a message that said it couldn't find the drive or something like that. Then there was a window to choose where I was copying from, and it came up with the hard drive name. Then another window came up with a disk image icon which is the place to copy to. I named it "Copyofharddrive", but I am not sure if this is right. I then pressed "Click" and then it told me it was going to erase the volume "Copyofharddrive" and asked if that was OK.
I am scared of doing the wrong thing and erasing my hard drive. I only have 12GB left on my hard drive too. I am trying to copy 100GB of data onto the disk image file. Will that work out?
I have never done this before. I don't understand disk image files. I just want to back up the data so that if the computer or the hard drive crashes I can then put the files on another computer.
Is a disk image a suitable way to do a backup and can I restore the hard drive exactly as it was on the hard drive on another hard drive using the disk image? Do I have enough space on the Powerbook to do the backup? Am I following the correct steps in doing the backup on Superduper? Why does it ask me if it's OK to erase the volume "Copyofharddrive" when I jsut created it?
Thanks for all your help.

If you only have 12 GBs of space on your hard drive then how will you fit 100 GBs of data into a disc image file on that hard drive?
If your external drive is not functioning then you cannot do any kind of backup to it. And, you cannot backup your hard drive to your hard drive.
What you need is another external hard drive with at least 100 GBs or more of free space that you could use for a backup. However, if you have the unpaid version of SuperDuper, then SD will erase the backup drive before making a full clone of your internal drive.

Is it safe to back up a disk image file when it's mounted?

Hi -
I use some small, encrypted ".sparsebundle" disk image files to keep my diary, banking info, etc., on. When I'm at the computer, I keep them mounted all the time.
Is it safe to let Time Machine automatically back up the .sparsebundle disk image files, even while they are mounted? Or would there be a possibility the backups would be corrupted, if the operating system hadn't written out cached data or something to the disk image file?
In other words, if I save any open documents on the mounted disk image, does the disk image file on disk always contain the fully-saved document and a consistent file system? Or could there still be some data cached in RAM, that would not be saved at the time the .sparsebundle file was copied? Is it always necessary to unmount a disk image before duplicating its .sparsebundle file?
Do I need to turn off Time Machine's automatic backup, and just do manual "backup now" after unmounting the disk images? That's a major pain in the behind... I really want to just let Time Machine do it's hourly backups as usual, but of course there's no point if the backups are corrupt.
Of course my own guess is "to be safe", I should unmount them before backing up. But again it's a big pain if it's not actually necessary. Does anyone know for sure?
Thanks...

My understanding is that Unix, generally, doesn't write everything out to disk immediately. There is caching in RAM to speed up disk access, including modified superblocks, modified inodes, and delayed reads and writes. Now, if you ask to read an individual file, the kernel makes sure all the cached data is written before it returns the read data. But if you try to do, for example, a block copy of the whole filesystem, the kernel doesn't know that, and there's no guarantee or expectation that the filesystem will be in a coherent state.
That's the purpose, for example, of the "sync" command - to write all this cached data to disk before unmounting, shutting down, etc., and, that's why the OS gets so upset if you just unplug a firewire drive. Because even if you've saved and closed any open documents, they haven't necessarily been fully written out to disk yet.
So what I don't understand, is how people are ever able to back up mounted disk image files without them getting corrupted. I mean, you'd think they would get corrupted all the time. It would be the equivalent of just unplugging your firewire drive before you made a backup of it, or of doing a block copy of a read/write mounted filesystem. There ought to be a very good chance of the filesystem being scrambled. So, why does it not happen?
Is there something different about the Apple filesystem, or Apple disk images? Or, maybe we're only talking about delay times in the cache of fractions of a second, so as long as you haven't written anything within a few seconds of the copy, and don't write anything during it, you're ok?
Even if Apple reps won't answer my question, the kernel and most likely all the low-level disk i/o and filesystem stuff is open source. Surely there's someone out there who would be knowledgeable enough to give a definitive answer? I was hoping to find someone like that here... I do appreciate your taking the time to answer my post, but maybe I need to go elsewhere, on some developers' mailing lists or something? Does anyone know of such a place I could start looking?
Thanks...

Importing Akai disk image file

I've just switched from Cubase SX4 to Logic Pro 8. Unfortunately I'm unable to use my library of Akai disk image files stored on my hard drives. Isn't EXS24 able to load from image files, like Halion does?
I went through the whole process of storing the CDs on my hard drive, because Halion lets you load directly from image files, making this method far better than using the actual CDs...
Help would be appreciated.

Go into Project/Project Info... and see if single-layer is selected in the pop-up. If it is, it should create a disk image to fit on a single-layer DVD-R.
I recommend a disk image burned to Verbatim DVD-R at 4X or slower using Toast or Disk Utility. You can set burn speed in iDVD '08 if not creating a disc image.
David Pogue also recommends Verbatim on page 356 of his iDVD 6 book:
iMovie HD & iDVD 6: The Missing Manual
Quoting David: "Cheaper brands don't use the same amount of organic dyes and are more likely to suffer premature deaths."
I buy Verbatim white inkjet printable in stacks of 50. Verbatim's part number: 94971. They have been flawless for me.
*Burning speed*: Go into the menu > iDVD/Preferences/Advanced. Look at the bottom of that window.

Suddenly cannot open an image file

PS 7 on a Vista machine with lots of RAM.
All has been working well for months and suddenly I cannot open any image file or start a new one. Tried re-installing from OEM disc and no improvement. Removed PS7 VIA the Windows utility and re-installed entire application from OEM disc with still no improvement.
When I try to open or start a new image the blue bar at the top of PS is illuminated, then I click on FILE and then on either NEW or OPEN. At that point everything stops. The drop down menus are grayed out and I cannot close the program by normal means. In order to close it I have to go to Task Manager and close the thing.
BTW: Sometimes Task Manager shows that the PS EXE application is using 44K and other times it shows about 7K.
Any suggestions will be happily recieved. Jack

I really hate to be a pain, but this has me stumped.
I tried to go to the preferences as you suggested but the same thing happens there. PS just freezes up and cannot be used at all. Even the red X at the top right of the screeen does nothing. I have to use Task Manager in order to quit the program.
I have removed PS from my machine VIA the Windows utility and reinstalled it several times with no improvement. I say that, but at one point I was able to open an image but when I tried to add another the system did the freeze up thing as above.
At some point I began to get sort of an error message during the PS bootup telling me that the PS interface font could not be loaded and that I should reboot my machine. I did that but there has been no change.
Frankly I cannot afford to buy time from Adobe to fix this so I am relying on you and the other folks on the board to hold my hand through this.
I thank you for your time and expertise.

Disk image files error when dragging files from them

any disk image file .DMG that i download and it either has a file to drag to the hard drive or has an application in it. They mount fine and i can lookinside them but when i drag a file out it seems to partially copy them but then comes up and says..
Sorry the operation could not be completed because an unexpected error occured (Error code -41).
If the dmg file has an installer it starts the installed and asks the normal question and permissions and then where to install to then try's to start but just errors again.
Anyone got any ideas. This is on a Mac intel Mini. Everything runs fine and as i said i fixted permissions it is an administrator account.
I have tried 3 disk images firefox opera and ablelive 5.2 they are not damaged or corrupted
thanks

I was having the same problem on my G4 Powerbook when I tried to install Adium and TextWrangler from disk images. After trying several things that didn't work I decided to see if my IP filter was the culprit. I opened PeerGuardian and disabled the filters. Then, I downloaded Adium again, and it copied easily from the disk image to my applications folder. Then, I tested TextWrangler and it worked as well. I don't know why that worked, and it might not be your problem, but I thought I'd pass on the info. Hope it helps.

Publisher hangs when I try to open an image file

Publisher hangs when I try to open an image file from:
right-click on image->Change Picture->Change Picture
The image is on my hard drive.
It also happens with powerpoint

Few Questions:
a. What version of publisher/PowerPoint are you using ?
b. Are you able to insert this image through Insert -> Image ? Image itself could be corrupt. Try to open it with some other editor ?

I tried opening my Mac files to windows by using Macdriver 8, however upon opening the file my previous mac folders were converted to windows shortcuts and upon returning to my mac pc, all my folders has a .lnk file extension which I cannot open.

Need help very badly since the hard drive I use is the only back up I have for my very old pics. Thank you...

Backup with cloning software your HD to have an exact copy of it as it is.
Use this methodology to recover your partition.

Opening an Image File

Hi! I'm trying to open an image file in an application using JFileChooser. As I open the file, I know that the file has already been selected but I don't know how to put it on the correct container. I'm trying to show the image on the upper box such that it would look like it is currently showing the current image and the lower box would show the filmstrip view of the images in the folder. Basically I have a JFrame and then a JPanel1 on the JFrame. I also have another JPanel2 inside the JPanel1 and it is in the place of JPanel1 that I want to put the image. Anyway, I'm stuck as to what should I use to contain the image on the upper box (JPanel1, currently it doesn't work for a JPanel). I can't see the image I'm trying to open. Any idea or help will be appreciated.

1. For Swing components, the method to override is paintComponent, not paint.
2. Why use ImageIcon when you can paint an Image?
