Previousversions are either copies of files and folders created by Windows Backup or copies of files and folders that Windows automatically saves as part of a restore point. You can use previous versions to restore files and folders that you accidentally modified or deleted, or that were damaged.
Right-click on the file and select "Restore previous versions". You'll get a popup that may say "There are no previous versions available" but if you're lucky, it'll start out reporting that it's searching (for possibly many seconds) for previous versions and then list the ones it's saved. Here's what it showed for me on a source file I've been working on recently but for which I had never requested any automatic backup.
NTFS is a journaling file system, meaning it's one that can track changes in files. That got turned on in Win7. Consistent with that being the start of the journaling, I found that it had snapshots of files I'd changed going back to my installation of Win7 but not of files that were older.
A file recover utility did the trick for me in a similar situation. Recuva has very good reviews and actually was able to recover several older versions of a power-point presentation I had inadvertently overwritten.
Free continuous backup software like DeltaCopy would allow you to pull the previous versions out of the backup destination, and that's a good thing to implement once you have recovered the desired version of your file.
When you modify and save (or a Windows app autosaves) a file, the prior version of the file is thrown away. It's probably still there, for Windows does not normally truly erase a deleted or modified file, instead marking the space the file previously used as reusable. If the file is erased, Windows then breaks the link between the space used by the file to the file name; if the file is modified, Windows changes the link of the file name to point to the new location.
Windows has written and replaced 3,600+ files so far today in six hours of use on my PC, and probably thousands on yours; it is very disk-intensive. Therefore, please abstain from using your PC for anything until you do these recovery steps.
a) Download the Testdisk software file for your OS.
b) Extract its files to a directory on a drive (an external USB attached drive is recommended) which was NOT used to save the desired Word file.
c) Read the README file.
d) Launch Photorec.
e) Specify recovery from the source drive where the file was.
f) Specify recovery to a destination drive (so it is not overwriting any clusters which might contain your data).
g) Start the recovery scan.
h) When scan completes, open the destination directory. A file name will have been randomly assigned by Photorec but the extension will match what you're looking for.
i) Open each of the recovered Word files which match the size (plus/minus 5%) of the file in question. Check to see what they contain. Delete them if not what you want.
Office (tested with Office 365 V1909) saves files for Word, Excel etc. in a similar way creating various temporary files. Instead of modifying the original file it creates a new file and renames and deletes the old one containing the old version.
IMPORTANT: make sure not to use the drive where the word file is stored until you are finished with recovering your deleted files. Space occupied by deleted files will be overwritten sooner or later when new data is saved on that drive.
When your computer is unable to boot to the operating system even after repeated attempts, SupportAssist OS Recovery automatically starts. This recovery environment enables you to diagnose hardware issues, repair your computer, back up your files, or restore your computer to factory defaults.
If your computer does not support SupportAssist OS Recovery, you can download the operating system recovery image. Learn How to Download and Use the Dell Operating System Recovery Image in Microsoft Windows.
Important: If the recovery image on the hard drive is corrupted or deleted, the computer cannot boot to the recovery environment. Newer Dell computers support BIOSConnect, a feature that allows you to restore the recovery image on the hard drive. Learn more about Using BIOSConnect to recover SupportAssist OS Recovery Partition.
Reset to Factory Settings: This option restores the original factory-installed operating system and software that was shipped with the computer. The local recovery image is available only on consumer platforms such as Alienware, Inspiron, Vostro, and XPS products.
To restore your Dell computer using the SupportAssist OS Recovery Cloud option, you must create a USB recovery media using the Dell OS Recovery tool. Follow the steps below to create the USB recovery media.
Reset to Factory Settings: This option restores the original factory-installed operating system and software that was shipped with the computer. The local recovery image is available only on consumer platforms such as Alienware, Inspiron, Vostro, and XPS products.
I upgraded my Macbook Pro that had Mojave (MACBOOK PRO (RETINA, 15-INCH, MID 2014))to Catalina Beta and this completely broke my Mobile Development using Flutter. There are numerous issues with version 10.15 that i just want to go back to Mojave.
If I go to the recovery menu and wipe the hard drive, then try recovery, which version will be installed? The original Mavericks that came with the macbook or the current Catalina beta i upgraded to recently. Is the recovery software also upgraded during upgrades? I don't have any backups as such don't intend to restore anything.
When you restore a Mac from Internet Recovery it restores the OS version that came with the Mac when it shipped. So if your Mac came with Mavericks than it will reinstall Mavericks. From there you can then reinstall Mojave right over top of the new Mavericks installation.
As for the recovery partition OS version, I am unsure of what happens to that during major macOS upgrades. I would think that it would not change as Internet Recovery works even with the recovery partition deleted. Which tells me that Internet Recovery is (at least mostly) built into the firmware of your Mac.
Going back a revision or two and then upgrading from there works perfectly well, it just takes longer. For that reason I always make a bootable USB installer of the last two versions of macOS and keep them in a drawer for eventualities such as these. 8GB flash drives are cheap and it takes little time to create a bootable macOS installer. Perhaps something to consider for the future.
The Recovery Partition is a full copy of the Pop!_OS installation disk. It can be used exactly the same as if a live disk copy of Pop!_OS was booted from a USB drive. The existing operating system can be repaired or reinstalled from the recovery mode. You can perform a refresh install, which allows you to reinstall without losing any user data or data in your home directory. Recovery can also perform a clean install, which resets all OS data.
To boot into recovery mode, bring up the systemd-boot menu by holding down SPACE while the system is booting, or by holding/tapping any function keys NOT used to Access the BIOS/Boot Menu (On non-System76 hardware, try the keys F1 through F12).
Note: These instructions assume Pop!_OS is the only OS running on your system. If you are booting more than one operating system you may need to change your boot order first, or manually select the Pop!_OS Disk from your BIOS/Boot menu.
Note: The Pop!_OS recovery environment will not have your WiFi password saved. Once booted into the live environment, you will need to reconnect manually to your WiFi in order to access the internet.
Note: The Recovery partition OS version will either be the same as the OS version that shipped with your computer, or the latest version to which the Recovery partition has been updated.
If the existing OS install needs to be repaired, the installer application should be closed. Use the installer app to select keyboard and language settings, then click the Try Demo Mode button in the lower-left corner of the Install page. Alternatively, right-click the installer icon in the dock and select Quit.
Caution: Do not choose any install or refresh options. Choosing install options could result in data loss.
Note: Once you have set up or accessed any of the filesystems, you will need to reboot the recovery environment to use any of the install options.
This will show you the name of the main internal drive, which will have 4 partitions on it. We will be working with the 3rd partition. If the main drive is an NVMe drive, it will be called /dev/nvme0n1p3 and if the drive is a SATA or regular M.2 drive, it will be called /dev/sda3.
Note: Pay attention to what the cryptdata group is called. If it is named something other than data-root, substitute the correct info into this next command. Make sure that -root is on the end:
With this last command, you will have root access to your installed system. Once the drive is accessed, commands for maintenance can be run on the installed system. For example, package manager repair commands. You can also access your files with Files via "Other Locations" -> "Computer" -> "mnt."
It is important to keep the Recovery Partition up to date as it is not updated with the installed OS. Updating the Recovery partition will allow you to reinstall the newest OS, instead of the previous Recovery version.
If the OS cannot recognize your RAID, you can create a virtual RAID from its components. Such virtual RAID can be processed like a real one. Standard RAID levels supported: 0, 1, 4, 5, 6. Nested and non-standard RAID level supported: 10(1+0), 1E, 5E, 5EE, 6E. Support for parity delays in all applicable levels. Support for customer-specified RAID layouts.
All R-Studio versions create IMAGE FILES for an entire Hard Disk, Partition or its part. Such image files can be compressed and split into several files to put it on CD/DVD/flash or FAT16/FAT32/exFAT. Then the image files can be processed like regular disks.
