Users of smartphones, tablets, laptops, or computers have personal files that surely can not be opened by others. But not infrequently our device, where the file was stored, could have borrowed someone else.
Not the intention of worse suspect, it could be someone who borrowed our device to open our personal files, whether it is intentional or not. So, we should take anticipatory steps to secure the file.
For that, consider how to secure files from others following.
If the file is a Microsoft Word document, we can use the password encryption feature available in Microsoft Word.
The trick is very easy. The feature can be found in the File menu> Info> Protect Document> Encrypt with Password. Type the password that will be used to access the document.
There are usually two options, whether a password is required to open a document in read-only mode, or a password is also required to open a document and make edits. Just choose according to your needs.
A similar method applies to other popular document files such as PDF, Excel, and so on.
If your personal files consist of one or more files, with multiple formats, from music, pictures, videos, documents, and so on in the same folder, you can secure it in one simple step using the archive program. One of the archive programs you can choose is 7-Zip.
After the program is installed on your laptop, right-click on the folder or file you want to give protection, then select 7-Zip> Add to Archive.
Next select the archive format you want and type in the password you will need to open the file or folder and select OK. Done, now your folder or file has been archived and secured with password.
