When I say accessed, I mean that just looking at a file triggers the OS to decompress it in the background and present you with an uncompressed version of it then letting you change it and recompressing it again for storage every single time you access theįile, which is why your machine gets slower. If you wanted to compress files before sending them to another drive, or over a network, or by email, then Compact wouldn't actually help at all because the files have to get uncompressed whenever they're accessed, especially before sending them anywhere.

Turning this off has to be done by booting into the recovery console, if my memory serves me correctly, and it's a real nuisance. Use this command is when they're removing disk compression because someone turned it on to save space. Very bad! It makes your computer very slow and is quite difficult to undo. It enables disk compression which is a total no-no. There are additional concerns with the Compact command. Or simply delete the output file at every execution.I fully agree that Compact is not the answer. So you can change the output file type to. If you you concatenated the information in a text file and then you want to concatenate it again in another file you can have duplication. for each text file it will create text file in folder out which will be the text starting from line 2.If the files have headers and you want to skip them then or you need to start concatenation from line n than you can do: Type *.txt > concatenatedFile.txt Solution 4 Concatenate with loopįor %x in (*.txt) do copy /b *.txt concatenatedFile.txt Solution 5 Concatenate without N first lines(headers) Open Command Line(check Solution 1 how to open it)Ĭopy /b *.csv concatenatedFile.csv Solution 3 Use type command.In the folder: C:/folderWithTextFiles you will have file named concatenatedFile.txt which will have all the information concatenated ( from all files ending with txt) Solution 2 Concatenate CSV files Or in Start Menu write cmd and open cmd.exe.Solution 1 Using Copy command for text files

You don't know the file names and you want to do it automatically you can use windows command line. If you need to concatenate 100 text files in one folder.
