If you found yourself in this situation too, before you despair, read this guide that will show you some methods on how to recover damaged files (in particular PDF, DOC, DOCX, XLS, XLSX) using some free programs for Windows or online services for data recovery.
Here is the first recovery method, which corresponds to a simple online procedure. Do you have a damaged PDF file? Then you don't even have to download a program, just visit the site OfficeRecovery, reachable at the following link.

The service allows you to upload the damaged PDF file to recover it; at the end it downloads a new PDF file that you can open with any PDF reader. Use it really very simple: click on the button Choose file to open the Windows file manager, where you will go to select the damaged or corrupted file; once finished loading press the button Safe charging and repair to proceed.
The site will proceed to recover your PDF document and automatically start downloading the repaired file. For the recovery of damaged files in PDF format definitely an excellent option, considering that just a simple Web browser (even on Mac or Linux) to fix damaged or corrupted PDF files.
From the same company that I showed you in the previous section, you can download a program on your computer that can proceed with offline recovery of corrupted file data, always in PDF formats.

In the new page click on the executable indicated by the red arrow (image below).
Once downloaded and started, just press the button Recover or on the key Start Recovery Wizard.
Select the damaged PDF file in the file manager and upload it to the program. At the end, click on Next to continue the recovery operation; a screen will appear first that will advise you to make a backup of the damaged file, then a screen where you can choose the destination path of the repaired file. In the last screen you can finally start the recovery operation by pressing the button Start.
In the vast majority of cases you will get your PDF repaired and finally accessible. The program is not foolproof and may not recover the PDF document; in this case I suggest you try the program recommended in the following section.
FileRepair a data recovery suite that can recover a large number of different files: documents (including doc and docx), images, videos and databases. There is no file that cannot be recovered with this program! To recover damaged and corrupted files with FileRepair download the right program using the following link.

You will immediately notice that there are numerous specialized tools for each type of file; download the version you need based on the file you need to recover. For this test I downloaded the tool to recover Word files, but the procedure is the same regardless of the format chosen.
At the end of the download install the tool; you will have the pleasant surprise of seeing an interface very similar to that seen for the PDF recovery program!
As I have already shown you just press on Recover or on Start Recovery Wizard to try to recover your damaged file. Confirm in the various screens with the Next button (don't forget the backup!) And in the last screen press on the button Start.
At the end of the process the file will be recovered. As already mentioned for the previous tool, there is no absolute certainty in the recovery of damaged or corrupted files, much depends on the extent of the damage and since time the file has been stored damaged, but an attempt can still do it.
Shadow Copies: Windows backups
One way to avoid using these programs every time you have a damaged file, use the shadow copies that Windows can create for each file in the system. If your damaged file can try to restore a shadow copy of it, right-clicking on the file and reaching the menu Property-> Previous versions.
If there are shadow copies you can restore them by clicking on the button Restore. These shadow copies are retrieved from recovery points, so make sure you often create a system restore point if you want to recover your files without the help of external programs.
