This is mainly why they’re so frequently accidentally deleted, error can not open recovery.dat, erased or hidden by malware, or wiped by whatever created them. Thankfully, you can reverse that by learning how to recover .dat files. Let’s begin.

Then, you can follow method 4. Here’s how repairing .dat files via disk utility works:

1. Windows

On Windows, use the set of steps we mentioned under the headline Use a disk error check to fix a corrupted USB drive in our “recovering hidden files from pendrive” guide. You can also run a Windows System File Checker utility by typing sfc /scannow in step 3.

2. Mac

Here’s how to run a disk check-up on Mac:

For both Piriform Recuva and UnDeleteMyFiles Pro, you must spot them manually and put a checkmark in front of their names before restoration.

Since .dat files often require the original application to load and recognize the text or binary data, you can’t open them directly. So, here’s how to decide which steps unexpected error occured when running game take:

1. I recognize names of .dat files

Great! Look up the application it belongs to, and navigate to its installation folder. Then, copy .dat files to the main folder or the designated subfolder or and try to load them within the application. Alternatively, rename the .dat file extension to match the extension of the application that generated them.

2. I don’t know what generated .dat files

Not an issue. There are a few more ways to recover .dat files:

  • Online conversion. Find any website that can convert files with .dat file extensions. Unfortunately, they’re frequently limited to text and multimedia files.

File Recovery

Use these instructions to manually recover the central model of a workshared file that has become corrupt.

  • Instruct users to discontinue use of the corrupt model.
  • Locate the backup folder for the central model, and copy this folder to another location.

    Revit stores central model backup information in a folder called <Central-file-name>_backup.

    This step ensures that the Restore Backup process does not attempt to access the corrupt model stored in the original location.

  • Restore a backup copy of the central model:
    1. Start Revit.
    2. Click Collaborate tabSynchronize panel (Restore Backup).
    3. In the Browse for Folder dialog, navigate to the copy of the backup folder for the central model (created in step 2), and click Open.

      If a dialog displays the message "Can't find project file <file_name>. Do you want to attempt recovery?," click Yes.

    4. In the Project Backup Versions dialog, select the version you want to use when recovering your file.
    5. Click Save As (do not use the Save command), and save the file using a different name.
    6. If a dialog asks if you want to open the file, click No.
    7. Close the Project Backup Versions dialog.
  • Correct issues in the restored model:
    1. Click File tab Open (Project).
    2. In the Open dialog, navigate to the restored model, select the Audit error 10053 localhost, and click Open.

      The Audit option scans, detects, and fixes corrupt elements in the model. When using this option, it may take some time to open the file.

    3. Click Manage tabSettings panel (Purge Unused).

      Purging unused items from the project makes it smaller and faster to open. Some of the unused removed items may contain small corruptions that have the potential of contributing to future problems.

    4. Close the file, and exit Revit, error can not open recovery.dat.
  • Clean out the Temp directory on all computers that store the central model or a local copy of the model.

    This step ensures that an overly-full Temp directory is not the cause of low disk space issues. It also forces Revit to create new versions of some files stored in Temp, thus ensuring that old files with potential corruptions are not carried forward.

    Important: Perform this task on the computer where the central model resides and on the workstations used by team members to work on local copies of the model.
    1. On your Windows Desktop, error can not open recovery.dat, open Windows Explorer. In the address bar, type to navigate to the Temp directory.
    2. Delete as many files as possible from the Temp directory.

      You will not be able to delete some files that are in use by other applications on your computer. The files that you delete will be automatically recreated as needed.

  • Move the local Revit files for the project and their backup copies to the desktop (or to another temporary location on your computer).

    Similar to the effect of cleaning out the Temp directory, this step forces Revit to create new versions of the project files.

  • Create a local copy of the restored central model to ensure that it opens without errors. Attempt to Sync with Central to verify that worksharing operates as expected.
  • Ask each team member to create a new local copy of the restored central model. They can then proceed to work with the restored model.

    How to Fix Issues with Org.openoffice.Office.Recovery.dat (Free Download)

    Org.openoffice.Office.Recovery.dat is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like org.openoffice.Office.Recovery.dat, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Portable) could share the same org.openoffice.Office.Recovery.dat file, saving valuable memory allocation, therefore making your computer run more efficiently.

    Unfortunately, what makes DLL files so convenient and efficient, error can not open recovery.dat, also makes them extremely vulnerable to problems. If something happens to a shared DAT file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when org.openoffice.Office.Recovery.dat is attempted to be loaded either when Portable is starting up, or in some cases already running. Some of the most common org.openoffice.Office.Recovery.dat errors include:

    • Access Violation at address - org.openoffice.Office.Recovery.dat.
    • Org.openoffice.Office.Recovery.dat could not be found.
    • Cannot find C:\OpenOfficePortable\Data\settings\user\registry\cache\org.openoffice.Office.Recovery.dat.
    • Cannot register org.openoffice.Office.Recovery.dat.
    • Cannot start Portable. A required component is missing: org.openoffice.Office.Recovery.dat. Please install Portable again.
    • Failed to load org.openoffice.Office.Recovery.dat.
    • The application has failed to start because org.openoffice.Office.Recovery.dat was not found.
    • The file org.openoffice.Office.Recovery.dat is missing or corrupt.
    • This application failed to start because org.openoffice.Office.Recovery.dat was not found. Re-installing the application may fix this problem.

    Your org.openoffice.Office.Recovery.dat file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Portable), or deleted by a malware infection. Furthermore, org.openoffice.Office.Recovery.dat file corruption could be caused from a power outage when loading Portable, system crash while loading org.openoffice.Office.Recovery.dat, bad sectors on your storage media (usually your primary hard drive), or quite commonly, error can not open recovery.dat, a malware infection. Thus, error can not open recovery.dat, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
