Windows 10: A question on copying files from a compressed folder to another compressed folder ..... ?

Compressed folders are often shown in blue for user convenience.


When Windows explorer copies files and also sub-folders from one compressed folder

to another compressed folder, does it decompress the file data ON-THE-FLY, and

then re-compress it again towards the destination ?


OR, does it leave it compressed and copy the data AS-IS ?


The logic here is that if it is going from one compressed folder to another compressed folder,

then there is no need to decompress it "in the middle" of the process.


Just wondering. :

No option to compress folder

Hi,

Thank you for posting your query on Microsoft Community.

I understand your inconvenience and we will surely help you to resolve the issue.

1. How exactly are you trying to compress the folder?

Follow these steps to check if that helps.

1. Locate the file or folder that you want to compress.

2. Right-click the file or folder, point to Send to, and then click Compressed (zipped) folder.

A new compressed folder is created in the same location. To rename it, right-click the folder, click Rename, and then type the new name.

If the issue persists then Perform
System File Check (SFC), and then check if this fixes the issue.

Follow the steps:

2. Select command prompt admin.

3. Type ‘sfc /scannow’ (without quotes) and press enter.

Copying Compressed Files

Yes, that is the way ntfs file compression works. A compressed file is decompressed as it is read. If the folder it is being copied to is on an ntfs partition and is an ntfs compressed folder, then the file will be compressed as it is written. If the destination folder is not compressed, neither will the copied file be.

EXT4 is a file system used by Linux. Windows does not support EXT4. There are 3rd-party apps that allow Windows to read EXT4 drives, but they do not provide write access.

The only practical way to copy a file in compressed form is to put it into a .zip archive (or .7z, or .similar) before copying it across to another drive.
