In this example, we will have two folders. PowerShell is a powerful tool to handle files and folders. We will first compare file and folders using PowerShell. Microsoft Azure Storage Explorer (MASE) installed.A local machine with Windows and PowerShell.We will try the following methods:Īfter that, we will show how to upload the files or folers to the Azure Storage in order to be queried in ASDW (we will show how to query these files in later chapters). We will also show how to synchronize them. In this article, we will see different ways to compare two folders in the local file system. When the files inside a folder are constantly updated, it is necessary to update the files in Azure and a comparision between the old and the new folders is necessary. How can we compare the content of two folders in order to upload only the new ones? However, these csv files are constantly changing and they need to be uploaded to an Azure Storage account. It is very common to work with csv files and query them using ASDW. Saves the backup unmodified file on saving new changes.When we have an Azure SQL Data Warehouse (ASDW), it is possible to query NoSql files using PolyBase.Refresh the comparison without saving files – you can re-check before you save the files.Alerts you when both files are identical.Remembers previously accessed files – helpful if you are working repeatedly on same files.Integration to Windows Explorer context menu to speed up your comparison process.Drag and drop feature to open comparison tool.Easy navigation to first and last differences (Alt+Home, Alt+End).Easy navigation between two variations using location bar or keyboard shortcuts (Alt+Up, Alt+Down).Difference pane to view differences in the focused line.Easy to copy changes among files (Alt+left or Alt+right).Edit the files inside the tool without requiring an external text editor.Compare two files / folders (including sub folders).Here are the features of this tiny free tool: This has all the needs a developer might look for. Most of such softwares are either paid or don’t offer all features a developer wants. WinMerge is an open source software which can ease the process of comparing files and merging them.
While I was in search of a utility to merge two files with comparing, WinMerge was the tool that helped me. In many such situations, we find file comparing and merging softwares play a vital role. Main advantage is that if there is a bug in latest release, one can identify that comparing the new code with the older successful one as mostly new version is created as an addition for what previous version had. This helps developers to check the differences between the files of previous versions and current one. A very good practice our software industry follows is maintaining versions.
