It compares the source and the destination folder and makes sure to remove additional files or copies missing files from the source to the destination. Robocopy with the /mir option, creates a mirror from the source into the destination.

It is a command to copy files with some advanced options. Robocopy has nothing to do with Robocop, the OCP or Detroit. This command is included in the command line (cmd). You can also synchronize both folders using the robocopy command. Once you have the files that changed, you can upload them to Azure. Finally, 21:42:02 is the last write time of the file russiancities.csv. PS C:\b> gci | select lastwritetime,name | out-file c:\output\destination.txtĬompare-Object $(Get-Content c:\output\source.txt) $(Get-Content c:\output\destination.txt)Ģ1:43:53 is the last write time of the countries.csv file in the folder "b" and 21:29:44 is the last write time of the same file in the folder "a". Next, we will do the same with the folder "b" and we will call the file destination.txt:

PS C:\a> gci | select lastwritetime,name | out-file c:\output\source.txt The following example stores the last write time and the file names in a file named source.txt of the files in folder "a": We can store the information in files of the folder " a " and folder " b " and after that compare the results.

The length of the files is measured in bytes. You can also compare the size of the files (length) using the gci cmdlet: The gci cmdlet will show the file names and the last write time: This attribute will show when was the last time that the file was modified (run this cmdlets in the a or b folder): The rows with Austria and Azerbaijan are included in the countries.csv file in folder "a", but they are not included in the same file in folder "b".Īnother way to compare two files is to check the last write time. Get-Content obtains the content of the files. You can compare files using the compare-object cmdlet:Ĭompare-Object $(Get-Content c:\a\countries.csv) $(Get-Content c:\b\countries.csv)Ĭompare-Object compares the content of the countries in folder " a " and folder " b ". It only detects what files exist and what files are missing.

#Using winmerge to compare folders code

The problem is that the Compare-Object cmdlet does not detect the files modified with the code used before. It will show the file differences between the folders:Īs you can see, the compare-object cmdlet detected that the folder " a " has a file named russiancities.csv not included in folder b. The Compare-Object cmdlet compares two objects. In the $destination variable, we will store all the files in folder b. The Get-ChildItem will store the files inside the folder a in the $source variable. PS C:\Users\OSCAR> Compare-Object -ReferenceObject $source -DifferenceObject $destination PS C:\Users\OSCAR> $destination = Get-ChildItem -Recurse -path C:\b PS C:\Users\OSCAR> $source = Get-ChildItem -Recurse -path C:\a The following cmdlets will allow you to compare Folder a and Folder b:

You can download these folders from the resource files at the bottom of this article. This file is different from the file in folder a This file is equal to the file in folder a Folder " a " and folder "b " as follows: Table 1. 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.

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.

#Using winmerge to compare folders update

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. When we have an Azure SQL Data Warehouse (ASDW), it is possible to query NoSql files using PolyBase.
