One common problem that can happen when working with files is when their extensions change and they become unreadable or unusable. This can happen due to various reasons, such as virus attacks or accidental actions from the user. Fortunately, there are ways to restore these files to their original state, and in this article, we will explore some of the methods that can be used for this purpose.
Cara Mudah Mengembalikan File yang Berubah Ekstensi
If you have a file that has changed its extension and become unreadable, you can try changing the extension back to its original state. To do this, first, you need to make sure that file extensions are visible on your operating system. In Windows, you can enable this option by going to Folder Options > View > and unchecking the box that says “Hide extensions for known file types”. On a Mac, you can go to Finder > Preferences > Advanced and check the box that says “Show all filename extensions”.
Once you have enabled this option, you can simply rename the file and change its extension back to what it was before. For example, if you have a file called “document.pdf” that has been renamed to “document.dat”, you can change it back by renaming it to “document.pdf”.

[Tutorial] Cara Mengembalikan File Excel Yang Hilang Di Flashdisk
If you have lost an Excel file from your flash disk, there are a few things you can try before giving up. First, you can try using a recovery software like Recuva or EaseUS Data Recovery. These software can scan your flash disk and recover deleted or lost files. However, it is important to note that the success of this method depends on how recently the file was deleted or lost, and how much the flash disk has been used since then.
If the recovery software does not work, you can try checking if the file is hidden. Sometimes, files can become hidden due to incorrect settings or virus attacks. To unhide a file, go to Folder Options > View > and select “Show hidden files, folders, and drives”. You can then check if the file is visible and change its properties to unhide it.
7 Cara Mengembalikan File Yang Berubah Format Karena Ransomware
Ransomware is a type of malware that encrypts your files and demands a ransom payment in exchange for the decryption key. If you have been the victim of a ransomware attack, there are a few things you can try to recover your files. Here are some methods:
- Restore from backup – If you have a backup of your files, you can restore them from there.
- Use a decryption tool – Sometimes, security researchers create free decryption tools for certain types of ransomware. You can search online for these tools and see if any are available for the type of ransomware that infected your files.
- Use file recovery software – Similar to recovering lost files from a flash disk, you can try using file recovery software to scan your computer for encrypted files and attempt to recover them.
- Check for shadow copies – Windows creates shadow copies of files as backups. You can try restoring the encrypted files from these shadow copies. To do this, right-click on the encrypted file and select “Properties”. Click on the “Previous Versions” tab and see if any shadow copies are available.
- Pay the ransom – While it is not recommended, some victims choose to pay the ransom to get their files back. However, there is no guarantee that the attackers will actually provide the decryption key.
- Work with a professional data recovery service – If your files are very important and none of the other methods work, you can seek the help of a professional data recovery service. They may be able to recover your files, albeit at a high cost.
- Reformat your computer – If all else fails, you can reformat your computer and reinstall everything from scratch. However, this should be a last resort, as it will erase all your files and settings.
Cara Mengembalikan Dokumen Excel Yang Belum Tersimpan
If you have been working on an Excel file that you forgot to save, there is still a chance to recover your work. Excel has an “Autorecover” function that can periodically save your file, even if you haven’t manually saved it yet. To try this method, open Excel and go to the “File” menu. Select “Info” and click on “Manage Workbook”. From the drop-down menu, select “Recover Unsaved Workbooks”. Excel will show you a list of unsaved workbooks that it has recovered. Look for the one you were working on and click on “Open”. You can then save the file with your preferred name and location.
FAQ
Q: What is the difference between renaming a file and changing its extension?
Renaming a file means changing its name, while changing its extension means changing the part of the file name that comes after the dot. For example, if you have a file called “document.pdf”, renaming it to “report.pdf” changes the name but keeps the extension the same. Changing the extension to “document.docx” changes the type of the file.
Q: Is it possible to completely recover files that have been overwritten?
It is very difficult, if not impossible, to recover files that have been completely overwritten by new data. This is because the original data is no longer there, and has been replaced by new data. However, if only part of the file has been overwritten, there is still a chance to recover some of the original data. File recovery software can scan the disk for fragments of the original file and attempt to recover them.
Conclusion
There are various methods that can be used to restore files that have been changed or lost, depending on the specific situation. Some methods are simple, such as renaming a file or using the Autorecover function in Excel, while others are more complex, such as recovering files from a ransomware attack. It is important to always have backup copies of important files, and to stay vigilant against malware and other threats that can compromise your data.
