We can make use ContentVersion entity to create files using Salesforce Apex. 

Use ContentDocumentLink entity to link the created the file to a record in Salesforce.

Sample Code:

String base64Content = EncodingUtil.Base64Encode( 
    Blob.valueOf( 'Testing File' ) 
);
System.debug( 'Base64 Content is ' + base64Content );
Blob blobContent = EncodingUtil.base64Decode( base64Content );
System.debug( 'Decoded Base64 value is ' + blobContent.toString() );
ContentVersion objCV = new ContentVersion(
    Title = 'Test',
    PathOnClient = 'test.txt',
    VersionData = blobContent 
);
insert objCV;
objCV = [
    SELECT ContentDocumentId
    FROM ContentVersion
    WHERE Id =: objCV.Id
];
ContentDocumentLink objCDL = new ContentDocumentLink(
    ContentDocumentId = objCV.ContentDocumentId,
    LinkedEntityId = '0013t00002XXRyDAAX',
