OS X :: Preview Is Unable To Open The File With Extension .dat?
Jul 8, 2010
IWhen I mount and open it, it contains three files: autorun.inf, edisk.dat and SVOLBRO.EXE. I am assuming that it is the edisk.dat file that I should be reading but I can not open it. I have spoken to the company who say that it should contain an encrypted pdf file. I have tried copying and renaming the file to edisk.pdf and then using preview but I am getting an error message saying the preview is unable to open the file.
I got a file named myfile.dat from my supervisor and he said myfile.dat is a helix database file. I tried to open that file after installing helix server 6.1.5, but I couldnt open it. I am really in a confusion that whether the given file is helix format file or something. Can anyone tell me that how to open *.dat file or how to identify the format from the file extension.
I try to open an Open Office spread sheet and it simply saves the file as another file with the .cpgz extension which does the same thing. This did not happen a couple weeks ago; I think my download for Apple updates may be the culprit. My OS X is now 10.7.3, I believe originally it was 10.7.2 but I could be wrong.
The original document is a zip archive but now "saves as" a .cpgz archive. I have tried the "Unarchiver", which I just downloaded, but it only creates another file with subfolders, none of which appear to have my original spread sheet. (To be honest, I never noticed this Open Office spread sheet file was a zip file until a few minutes ago when I tried to unsuccessfully open it).
I recently had to switch out the hard drive on my Early 2011 13" MacBook Pro. When I got the computer back from the Apple Store I began loading my old content onto the machine. When previewing and opening files, they would appear with randomly coloured splotches of pixels on them. This continues to happen when browsing folders on my machine.
The files do not show up with splotches on other computers, and are not in the same places each time I open the file, which leads me to believe they are problems with my machine and not the files themselves.
I hypothesise this is the graphics card, but I don't know enough about the hardware.
Ok I have been trying to find the reason why this is happening. I am having an issue with the icons disappearing, the file is still there and you can click on it if you click on the words, but the icon is not there just the icon is gone. The icon that is not showing up is the folder icon primarily. I have searched several different sites and can not find an answer to my problem. I have included a link to view what my desktop looks like with the files pictured so you get an idea. URL
I have tried to do the equivalent of a (rebuild desktop) desktop reset which was a program I downloaded from apple: URL
It did not help either and after installing that and doing the reset. Now when I go to open a picture, it opens in color sync instead of preview. The only way I can open a picture in preview is to open preview and then open a picture through it. It is like color sync is the default for some reason. Does someone know how to fix this? But my main concern is tis icon issue I am having. I don't know what to do as it is making it very hard to work. This even carries over to my external drives when hooked up. I need help as I do not know why it is doing this. : (
As far as other information, I just installed Tiger a few months ago if that helps any and this is on a mac mini. Other than that everything has been the same. I have relaunched the finder through opt+cmd+esc but it is not available to relaunch through right clicking the icon on the dock. Also it no longer allows me to drag a picture file over a program like Photoshop in the dock to open it in Photoshop. What is going on here? This getting crazy!!
Today I tried opening my keynotes presentation file to make amendments to it and when I double clicked on it, the program loading bar only loaded up a third of the way and then hanged. I then tried to save it to a flash drive and use it on a different computer, but when I tried to copy it over to the flash drive it gave me this error: "the finder cannot complete the operation because some data in "garment styles" could not be read or written error code - 36".
I have tried changing the file extension to a zip, then unzipping it and then renaming it but that did not work.(It wouldn't let me unzip it). I have also looked at the index file name to see if that was the problem, but that is as it should be.
I have also tried uploading it to a website and emailing it and it will not let me.
Is there anyway I can recover this file as I have been working on it for over a month and it is due next week, or will I need to start again?
ok trying not to get a panic attack here. I downloaded espionge to encrypt my valuable files and while it was encrypting (AES 128 bit i think) the program froze and I had to Force quit it. Now I try to open my file (that i was trying to encrypt) and it looks f*^&# up. I can't open it, and when I tried to unmount the partially encrypted file, espionage gave me errors that it couldnt recover the original file.
I had basically all my life's valuable accumulated data in that folder (it was 10 Gb+). I will praise anyone to the end of my days that can somehow tell me how to restore my file to its original state. Usefull info:
1) AM planning to pay gazillions for recovery software if need be, but free alternatives are always better.
2) I never secure delete if that helps
3) I still have the .sparseimage for the file created by espionage. (P.S. sparseimage's size looks really close to the orignal, also 10 Gb +).
4) Newest version of OSX, and have an IMac.
5) after incident I haven't done anything (no installations or downloads) apart from writing this.
6) the encrypted file was gonna be in HFS+ i think
I would like to direct my Documents, Pictures, and "Other" to 3 folders in my downloads folder upon downloading them, either with Safari, with Finder, Folder Actions, Automator, or with any other free tool that does not take up too much CPU load.
i have a ppt saved on my pendrive which i got saved from windows as (.pptm) but now when i tried opening it on my macbook it shows a message (�CORPORATE GOVERNANCE org..pptm� could not be handled because Keynote cannot open files in the �ZIP archive� format).
I'm trying to install a printer driver for my Epson Stylus Photo 2200 printer. I downloaded a file from the Epson support site that contains the correct drivers (according to the webpage directions) which has the label: epson11019.sea I am supposed to be able to open this file by double-clicking on it, but all I get is an error message that reads: "Open Dictionary Unable to open the dictionary or extension of the application because it is not scriptable. OK" I tried the help menu and was told to drag the application onto the Script Editor but get another message to the effect that it is not readbale, or something. The file [epson11019.sea] is supposed to be for the Mac OS X system but I am at a dead end here.
I was filming a video in Photo Booth from my webcam, and I assumed that quitting Photo Booth would stop the recording. I was wrong. It seems to have not closed the file properly, and now I am unable to open the file or do anything with it. how I can recover it and make it openable?
I recently used time machine for the first time in a long time. I use my external HD USB for the backup. After the back up was complete, I unplugged the USB cable. I got an error that I needed to put the HD away first (I wasn't thinking). And I didn't pay attention to the error either.
I thought the data was gone, when I didnt see the data in the back up file. I do see the back up file with that date on it. In the file is the .InProgress file. In that file, on right clicking, I see the contents of one folder. This folder has a very long name of numbers and letters. It shows no contents in the finder. THough I know the files must be here. The HD has capacity of 100 Gig. There is only about 20 gigs showing on it. Though there is only 20 gigs available. So, my back up data is there on the HD, and I assume it's in this "empty" file.
When I try to use Software Update it downloads the file but will not open, and shows me the error message, "Update can't be installed - Software Update could not expand the package correctly". This happened the first time a week ago and I thought was an isolated event, but it is happening again, so obviously there is a problem with Software Update. If I download it from Apple through Safari it works.
Using a newly purchased Sony DCR-SR47 Handycam, I am attempting to import the still images from the Memory Stick Pro Duo (preferably into iPhoto). Using the Sony instructions provided here [URL]... when I open the file all I see are MEMSTICK.IND and MSTK_PRO.IND. Unfortunately when I attempt to open files with the .ind extension it comes up as an unrecognizable format. The images are viewable on the camcorder but I can't seem to open the file.
As stated in the title, when I try to download a file from the internet, clicking on the link associated to the file will not start a download, but instead opens a new tab in my browser showing the url of the associated file. If I then right-click and choose 'Download linked file as...' the file can be downloaded with no issues in most of the cases, at least as long as the website allows right-click downloads to happen.I have tried resetting Safari, emptying the cache and, of course, updating my software. It is a midly annoying problem, but it doesn't happen when I use other web browsers in my iMac.
Info: iMac (21.5-inch Late 2009), Mac OS X (10.7.4)
I have a document that I've been working on in Text Edit. When I went to open it today it would not open and I got the message "the file could not be opened because it is not in the right format". I don't remember saving it any differently, last time. The only thing I did was change the font to a larger size, a few minutes before I last saved it. Could it be that it then became such a large document that text edit can't open it or is there something else I might have accidently done.
I created an image of an external hard drive to back it up, then I checked it and it opened fine. I moved the file to another drive and initialized the original drive and dropped the dmg file back onto the drive. Now it won't open. I really need the files on that drive. Is there any way at all to open it if even for a short time to retrieve the files?
I once changed the file extension on a ppt presentation sent to me, and it finally opened. I read about it on here, but cant find the original forum thread and cant remember the extension: pxt or ptx or something similar.
I just recently download a video file from Deposit Files & it downloaded without any extension? I am looking for a way to find out its extension & be able to open this video & play it in real player or quicktime as intended. Any time i click on the file the usually gibberish opens up in textedit.
I have close to a hundred music files that won't play, they have no file ending (.*). They were transferred from a now formatted computer (no way to recover). I have no idea how to get them to work. If I give them an AAC ending RealPlayer will give me the following information but it won't play them. Since it tells me the length of the song it must somehow recognize it.
