Unable to open external drive XLSX files

Hello

I have a macbook El Capitan having installed Office 365, with the latest version of excel running. Recently, I have been unable to open excel (.xlsx) files from my external hard drive because it gives me a message stating that it is corrupt and offering a repair option - which also fails. I can however;

-Open the same file on a windows PC 10

-Open the file in numbers

-Open any other file on the hard drive (document images, PDFs, Word etc.) in native mode without any problem

-C' is essential, I can copy the file to the desktop and it opens in Excel without any problem.

I am at a loss of what it might be.

Thank you

(my apologies if this is in the wrong section)

It seems that there is a problem with the Mac from Microsoft Excel version, opening files from an external drive. Looks like a Microsoft problem that should be reported to them.

    How drive letters are assigned to external drives and file path names? MyBook is a drive letter (M) when it is connected to my desktop computer and another letter (L) when it is connected to my husbands office, USB key has the same letter, no matter what usb port is used. Is the letter assigned when the file is created and does not change? or is it to the port to which it is connected to? in what computer?

    Each computer assigns the player to the first drive letter not used in alphabetical order.  It makes no difference what port it connects to.

  • Could not open any project or external drive backup files

    Hello world

    The way I got things set up, is that my final cut pro project has been saved on the external drive. Whenever I open it, it picks up from the external hard drive. Recently, I had a power outage that stopped my external drive and crashed my FCP X. When I turned things on, I kept getting an error that the FCP closes unexpectedly. I have the option to ignore or to reopen. I tried to open my backups, but I get the same error. Sometimes he was telling me to save it to the internal drive and it would actually open, but I get a lot of lack of links to files. My mac doesn't have a lot of space, so I need to be stored on the external hard drive.

    I thought that maybe it's my sharing and permissions of the drive in the menu get info, then I have everything given access, but does not work. I tried trashing the preference of the FCP, but that did not work.

    I have version 10.2.3 and on Mac OSX 10.11.6 El Capitan

    Could someone help me please? I don't know what else to do.

    Welcome to the Microsoft Answers community.

    In order to open the .xls files, you will need to purchase Microsoft Excel or at least download the Viewer. You can download the last one here.

  • What happens if my external drive "working files" breaks down?

    I use two external drives to save and back up my files.  The files organized, edited the reader of 'work'.  If the drive working breaks down, how can I restore it from the player of "backup" that contains just the original, unmodified, the files placed in folders by date of importation?  I realize that catalogue contains all the changes, but how to return to the Organization?  Anyone using a Raid 1 configuration for two disks mirrored?

    Maybe I don't make myself clear. How to take the 'back-up' disc, containing original photos not published, ordered by date of import and convert the disc format 'work' catalogue in the LR4 will recognize?

    It's great that you think about it now, instead of this disaster.  Play well!

    The "second copy" option in the dialog box import is ideal for temporary backup, while the pictures in your main backup system, but it is a nightmare to restore from.  There are options to rearrange disaster, but it is better to avoid.

    Rather than RAID1, I would suggest looking at backup synchronization software or a file - I love Vice Versa on Windows or Chronosync on Mac - to keep a copy in the mirror of the work unit.  If you use RAID1 and photo gets deleted or damaged, it is immediately deleted/damaged on the second disk RAID, while the file backup/synchronization software would go less often, giving you a chance to recover it.  Many also offer one option 'archive' for deleted photos, moving them to another folder.

  • I am unable to open and copy the file encrypted after formatting my computer

    I just format my computer before formatting, I take any backup of the drive c. but 1 file is encrypted on my backup now, I'm unable to decrypt this file and is also impossible to copy and open this folder. Please help me with this.

    I assume you have XP Pro and that you encrypted files by using the Encrypting File System (EFS).  When you use EFS, the these files decryption key is stored encrypted with your certificate store.  When you use EFS, you * MUST * back up your certificates or risk permanently losing access to your encrypted files.  Details are provided in this article which is required reading if you use EFS:

    "Best Practices for encrypting file system"
      <>http://support.Microsoft.com/kb/223316 >

    Jump down to the paragraph "why you should back up your certificates.
    Line background here, is that you have two options to recover the access to these files.  The first is to restore your certificate from the backup of the certificate that you created by the article above before you reformat your computer.  The second option is to completely restore your previous system from a backup of the image-style you did your system before reformatting and reinstalling.  Otherwise, I fear that you have permanenty lost access to these files.

    EFS is affectionately known as the 'Recycle Bin delay' in this forum.

    Hello

    1 how long have you been faced with this problem?
    2. don't you make changes on the computer before this problem?
    3. What is the brand and model of the computer?
    4. who help and support files are you referring to?
    5. what exactly happens when you try to open it? You get the error message?

    cssauth.exe is related to the Client Security Solution.

    Step 1: Try disabling startup cssauth.exe in the configuration of the system.

    Here's how:

    1. click on start > run.
    2. type msconfig and press ENTER.
    3. click on the Startup tab.
    4 locate cssauth.exe, and clear the check box for this.
    5 restart the computer and check for the issue.

    Step 2: If you still get the same error at startup then perform the clean boot on the computer.

    From your computer by using a minimal set of drivers and startup programs so that you can determine if a background program is interfering with your game or program. This type of boot is known as a "clean boot".

    Reference:
    How to configure Windows XP to start in a "clean boot" State
    http://support.Microsoft.com/kb/310353

    When you are finished troubleshooting, follow these steps to reset the computer to start as usual:

    1. click on start and then click Run.
    2. type msconfig and click OK.

    The System Configuration Utility dialog box appears.

    3. click on the tab general, click Normal Startup - load all services and device drivers and then click OK.
    4. When prompted, click on restart to restart the computer.

    I would also ask you to contact the manufacturer of the computer because the problem is with the client security software that is provided by them.

  • Unable to open encrypted drive up to that "turn off the csrutil.

    I was using OSX 8.5 until a few days ago. One of my discs is encrypted. For some reason I couldn't open it for a long time. A day after a reboot, the system refused to open it (I just restart my Mac Book every now and then). I tried several combinations of the password, nothing helps. It was not so important, because the disk contained only the old data.

    Two days ago, I have updated to OS x 11.5 and gave him a new trial, nothing had changed.

    However, today, I needed to disable the security protection by a "turn off the csrutil. A nice side effect is that I can re - open the disk encrypted with my known password.

    Isn't it strange?

  • If you move files to an external drive in PSE 7, are these backup files when you catalog backup

    My catalog is now about 50 GB and I want to decrease its size so that it takes up less space on my hard drive, and more important, so my backups and restorations do not take as long.    Files are not to be modified in the future then why keep saving them?  If I move the files on an external drive using files offline, copy/move files on the removable disk will be backup items these files as well as files on my C drive when I backup my catalog?

    If not, can I move files to a new catalogue and catalogue of dangerous data (such as albums, tags, etc.)?

    Thanks for any help.

    function() {return A.apply (null, [this] .concat ($A (arguments)))}

    When restore you to the original location on the destination computer, the fact that restoring average the same path where the files were on the source computer?

    Yes, the exact same path.

    function() {return A.apply (null, [this] .concat ($A (arguments)))}

    I used this option once when I saved on my XP computer and restored to my Vista machine.  It took me a long time to get rid of extra files generated by Vista.

    If you're moving from XP to Vista and your records are under C:\Documents and Settings\, Vista will create aliases to your user folders to maintain compatibility (since Vista has a different naming convention for the files of the user).  Vista itself will not create additional folders, but programs like the PES can be confused by having two different names for the same file.

    function() {return A.apply (null, [this] .concat ($A (arguments)))}

    I now store everything (files catalog and photos) in a folder with the same name under C:\ on both computers.

    As long as it is not under C:\Documents And Settings, then use the original location option to restore to the same exact path.

    The option new location / Restore Original Folder Structure will preserve your folder hierarchy, but create very long paths by adding in the root files, for example \users\ellis\pictures and it is difficult for many people to collapse these unnecessarily added files.

  • Not able to take backup on external drive.

    Original title: backup and backup Open files;

    I have just startde to use Office 2007 with Windows XP Pro. I'm doing a backup on my external drive "F". When I try to open the file or folder of this drive in R / clicking > open, it brings back me to the wizard to backup & restore instead. The window that opens when I R / click on the file/folder on drive F is so different; It shows a selection "Edit" at the top, followed by "Open", followed by "7-Zip", 'open with' ' Scan with "," send to "etc. No "Explore". I was unable to open the folder or file in any given method. Make the backup I use the Backup Wizard and have used the advanced, and normal method. On the F drive backup icon appears, but it seems to be empty or such. What I do wqrong? I need your HELP, please and thank you: HDScala

    Hi JoelJ1964,

    Thank you very much for your help. Before using this laptop, I used my old computer with WIN XP Pro and Office 2003. I was able to back up to the external hard drive F and then open and work with files or files, as in copy and paste to the C drive everything I need. Office 2007 does not work the same? I use Windows XP pro here as well. In addition, I seem to have several folders "My Documents" on "My Computer" tree. A top under the desk, then 'User' in Documents and Settings, I 'My Documents' and 'recent Documents '. In the latter folder, I found all the backups, many icons, real backup folder containing only 1 KB, and most appear to be shortcuts. I simply do not know what is happening here, although some files or folders are containing the info that I have previously saved in My Documents.

    How can I know what a folder, when I returned to the Backup Wizard, follow the instructions in the wizard and the file or restore the right folder? I'll be able to see this only restored?

    Any suggestions or help or advise would be appreciated. Best regards, HDScala;

    Hi HDScala;

    With all due respect, you're wrong to be able to open and edit files after using backup windows on your other computer. Using the backup utility is not the same as copy and paste. When you use backup image is created similar to the image below. When you use copy / paste, you are able to access immediately, open and edit the file. Backup doesn't work the same way. It compresses the files you selected to save then creates an image of the same thing. There is no option to change the format that uses the backup utility files.

    The link below is a tutorial on windos xp backup utility.

    http://www.Microsoft.com/windowsxp/using/Setup/learnmore/bott_03july14.mspx

    As for the several folders "My documents" you see, there's such a folder for each user account on the computer, including the default Administrator account. These records are quite normal.

    The only strange thing, that you have pointed out the fact that you see the individual files in recent Documents. You should see the image created by the backup utility along with the documents you accessed physically.

    This is probably due to a problem with uncompressed metadata stored in the workbook. In most cases, the issue is found in the first journal in hidden forms. There are a few options to fix this. This file should also be open, but it may take a very long time, in some cases, the file opens fine with SV disabled in other cases, it won't matter.

    Option 1

    Open the file (it may take a while)
    Save the file under a XLSX file.
    Try to open it again.

    Option 2

    Open the file (it may take a while)
    Right click on the tab for the first worksheet calculation and "select all sheets.
    Right click on the tab for the first worksheet and "move or copy...". »
    In the dropdown select '(nouveau classeur)' and check 'create a copy '.
    Save the new book in any format.
    Try to open the new book

    Option 3
    Open the file (it may take a while)
    Run the following with the first worksheet selected VBA:

    Void ClearFunctionCache()
    For each oShape in ActiveSheet.Shapes
    If LCase (left (oShape.Name, 19)) = "workbkfunctioncache" then
    oShape.Delete
    End If
    Next
    End Sub

    Save the new book in any format.
    Try to open the new book

    In any case, try the refresh operation and save and reopen the file to ensure that the problem does not return.

    Make a backup of the original file before making any changes.
