Can I delete Data1.cab files?

I am doing some file maintenance and I notice that I have 3 Data1.cab files in different folders.
C:\program files\adobe\acrobat\setup files\acropro\efg
C:\program files\adobe\acrobat\setup files\acropro\efg_
C:\program files\adobe\acrobat\setup files\acropro\enu
The files are quite large, one over 440 mb. Can I delete all or any of these? Once I'm installed and running do I need them?
Thanks.
Nathan

That would be a bad thing. You probably wouldn't be able to uninstall
or repair Acrobat.

  • Can I delete Data1.cab from from Setup Files?

    I just noticed that I have HUGE (691 MB) file in C:\Program Files\Adobe\Acrobat 9.0\Setup Files called Data1.cab.
    Can I safely delete that file without interfering with the operation or later removal of Acrobat?
    Thanks in advance!

    May I ask how could I make my answer more "definitive"?
    Should I provide technical details on what SOURCELIST or SourceDir properties are in Windows Installer Service and how they get registered?
    Well, what I meant by 'definitive' when I referred to other places on the Adobe forums, was that people in those threads seemed to be speculating that this might be the reason Adobe keeps a 674 MB file like that just hanging around.  In those same threads people suggested a variety of possible reasons so I couldn't tell if people were just taking their best guess.   Some people thought it might be needed for uninstall, for instance.   
    Also, if repair IS the purpose of the file then why don't I find similar files for all the other apps that got installed with CS4 - Photoshop, for example, or Dreamweaver or the Flash development software?    Is Acrobat uniquely subject to corruption, compared to their other software?
    But anyway, since I have have my original install DVD, if Data1.cab is just there for repair, and it doesn't need it for any normal operation or uninstall, it sounds like I can blow it away with no worries, right?

  • Can I reduce the size of my Data1.cab file?

    I have a Data1.cab file that is 1.275G for Acrobat 9.0.  This seems very large to me.  Is there any way I can reduce the size of this file?

    Why do you care what size the installer is. When finished with your installation you can and should burn it to a DVD for safe keeping. You don't need to keep the installer on your hard drive.

  • Data1.cab file too large in Default User folder...

    We are experiencing an issue on our project where a file (Data1.cab) is created within the
    Reader 9.1 and Reader 9.3 folders of the ...Default User\Local Settings\Application Data\Adobe folder location.
    These files are too large for our system and taking up unnecessary amounts of space on our hard drives (averaging 104 MB in size each). Every time a new user logs onto the system, their profile is created and these 104 mb Data1.cab files are created. We want to know how we can:
    a) automatically off-load these files to another location
    or
    b) change a setting that would not generate the Data1.cab files every time a new profile is created or at least reduce the size of the file significantly upon creation.
    Any advice on the matter would be much appreciated.
    thanks,
    - Brian

    Thank you for posting your insight on the matter.  However, we are looking to be a little bit more pro-active on the matter.  Is there a setting or an entry in the registry we can apply that stops the files from being created?  Or a sample batch file you've created to automatically delete the files upon creation?  Please respond at your leisure.
    thanks,
    - Brian

  • Data1.cab file cannot be used

    I was just given my daughters Ipod since she got a new one and am trying to load the software and get that the data1.cab file can not be used, it says it could be a network error, an error reading from the cd or a problem with this package, I than said to retry and got the same message, than said to ignore it and got internal error 2350 and than error1603
    Can anyone tell me what to do.

    let's try getting an itunes 7 installer log to the Apple engineers for a look.
    1. Open a command prompt window. (Start menu -> Run. Type in "cmd". Hit return.)
    2. Drag and drop iTunesSetup.exe onto the window so that the full pathname of the file is at the command line prompt.
    3. Type in a space, then the following line:
    /l*v C:\log.txt
    4. Hit return.
    5. The installer will create a log file:
    C:\log.txt
    Find that file and send it as an attachment to this email address.
    in the email to Roy, be sure to include the following information:
    - A link to the thread on Apple Discussions where the issue is being discussed
    - The username you are using in the thread
    - The version of iTunes you are using or trying to use
    - the version of Windows you are using (mention service packs)
    - A concise description of the issue you are seeing
    - The exact text of the error message you are seeing

  • Error 1311 - missing Data1.cab file

    I have researched this problem and still need help because I think my problem is different. First off, here's what happened...
    I purchased and legally own CS4 Master Collection. I had it installed on my desktop. I ended up uninstalling Adobe Acrobat 9 pro. A week after doing that I had to do a system restore to a restore point BEFORE I uninstalled it. So the program obviously showed up again but with the error. Because of the error I uninstalled CS4 completely, thinking I could reinstall it again. Well when I went to reinstall, it already said that Adobe Acrobat 9 was installed already so I wasn't able to select it again to reinstall. All of the other programs installed just fine. And then when I go to try repair Acrobat 9, it doesn't even show as being installed with the other CS4 collection. And when I double click to open it, it does open and when I go to repair it, it will open up an installation box saying it's going to install and then gives that error 1311 saying the Data1.cab file is missing. And it is missing.
    So my question is, how do I uninstall it when there's no option to uninstall it. Or how do I get the needed Data1.cab back in place to see if it will indeed install properly?

    Sorry about that, my desktop is running Windows Vista home edition.
    I can uninstall every program through the add & remove programs feature except for Adobe Acrobat 9.0 pro. It doesn't show up as even being installed. Same with when I uninstalled and reinstalled it. It didn't give me the option to select it for installation.
    Ok, I'm just uninstalling the programs again and will run the cleaner tool. Fingers crossed that it removes it!

  • CS2-installing error "data1.cab" file corrupt

    I have recently reformatted my C drive and reinstalling programs.
    I tried to reinstall my CS2 Photoshop, but received error message that the "data1.cab" file was corrupt or missing. Could not install program.
    I don't know how to fix. Could someone please help?
    Thanks,
    mmspry

    from a disc? try to copy the photoshop folder from the disc to the desktop, then run setup from there. however, you might have a bad drive or a bad disc. if the setup from the desktop fails, try installing on another machine. if it still fails, the disc probably has a problem. if that works, maybe your drive needs replacing.

  • How can I delete an old file from my library on iTunes

    Occasionally I have to replace PDF manuals with ones that have been updated.  But after I sync the new file the old one remains on my Mac itunes library.  How can I delete the old file?  So far all I do is deselect the old file but it's still there.  Sooner or later there will be more old files then current ones making it hard to manage.
    Thanks in advance.

    You can do this with or without the iPad connected to your Mac.
    Launch iTunes on the Mac. Click on Books under the Library heading. Click on the PDFs. Then click on the PDF that you want to delete in order to select it, and go to Edit>Delete and follow the on screen prompts.
    if you are using iTunes 11 and do not have the sidebar enabled, and wish to do so, go to View>Show sidebar or use the keyboard shortcut OPTION+Command+S.
    If you do not want to enable the sidebar, the library items can be accessed in the button in the upper left corner of the iTunes window.

  • Trying to use a new, larger external hard drive for my Time Machine backup.  However, every time I start the backup, it gets started then fails.  And, I can't delete the few files that did save on the external.  Sort of a catch 22.  Any ideas?

    Is it a USB hard drive?  USB hard drives have the problem of not giving full speed if they are hooked up on the same bus as keyboards and mice.  Double check your profiler to make sure that is not a problem.  If it is Firewire, make sure there aren't other firewire devices in use at the same time.  I recommend not only keeping a Time Machine backup, but also a clone, and if you do use Time Machine, to make sure the Time Machine drive or partition is at least twice the size of the original drive.

  • How can I delete all the files in the Adobe CS4 Master Collection from my machine?

    How can I delete all the files in the Adobe CS4 Master Collection from my machine. I have tried Control Panel but it will not do anything, there are no error messages, it is like as if it is ignoring my instruction. Why should it be so difficult to delete programs one does not want. Any ideas please.

The file is present but is empty (0kb) so when I hit 'retry' the same message just appears again.I am downloading from Adobe direct, not from a disc and am downloading onto a PC.

  • Data1.cab file not extracted when installing Acrobat X on windows under VMWare Fusion 4.0

    When extracting the files to the installation folder, the Data1.cab file is created but it is o kb value. Then when running the setup file, there is an error generated because the setup cannot see a valid data1.cab file

    Manish_1988,
    Thanks for the suggestion but after trying all of the suggestions, I still
    did not have any success.
    I ended up extracting the install files while I was in Oracle Virtual Box
    then used the install files when I was in VMWare Fusion. A bit convoluted
    but it worked.
    Again, thanks anyway.
