Windows 10: Ntfs file compression - how to remove from folders

Hi. I just noticed on my small 32GB netbook that a folder on the desktop has the blue arrows on it signifying that Windows 10 has compressed the folder and its contents on its own I guess because I don't have a lot of space left on the netbook.

I found this tutorial and used a reg file to disable compression:

Enable or Disable NTFS File Compression in Windows | Tutorials

I also right clicked the compressed folder/properties/advanced/ deselected compress contents to save disk space/ ok and this uncompressed the folder. I've noticed now that a macrium folder not in that folder is compressed.

My question is how can i tell which folder files have been compressed by windows besides just searching around? Is there an easy way to uncompress whatever it compressed in one action? Thanks.

:)

 

NTFS Compression of copied files

I'm experiencing an odd issue in Windows 10 that involves copying files that are compressed using the NTFS filesystem to another folder that has the compression flag set (so that when the file is
copied, not moved, it is compressed in the destination folder).

The issue is that when the file is copied to the folder, the filesystem is not releasing the uncompressed copy of the file (as it should) after compressing. Thus, the disk is recognizing that
double the space is needed to store the file (e.g. if the file was 500MB, the remaining capacity for the disk will be 1000MB less). In Windows 7, this behavior is not being seen (i.e. after the file is compressed, the uncompressed file is released,
showing the correct amount of space used.)

I've experienced this on several (actually all) Windows 10 installs, so I'm wondering if anybody else has seen this.

Of course, restarting the computer seems to correct the reported free disk space remaining, but while in a session, I've had to decompress a file manually, then recompress it to have the filesystem report the correct size. The system believes that much more
disk space is being consumed that what is really there, and it is leading to insufficient disk space errors (in testing out the problem, I made a dummy partition and copied the compressed file to it).

I would write this off as a corrupted installation, but I've seen it on good installs also. I've also reported the problem in the Windows feedback community, in case it is an actual bug.

Thanks for any help.

 

Files in C: drive automatically compressing?

Hi Marvin,

You can set the compression state of folders and compress or decompress files by using My Computer or a command-line program called Compact. We recommend following these steps to set a folder in a decompression state:

• 
  Start Windows Explorer . In the left pane, select the folder you want to compress or decompress.
  
• 
  On the File menu, click Properties to display the
  Properties dialog box.
  
• 
  On the General tab, click Advanced .
  
• 
  In the Advanced Attributes dialog box, clear the Compress contents to save disk space check box, and then click
  OK .
  
• 
  In the Properties dialog box, click OK .
  
• 
  To keep existing files or subfolders in the NTFS folders in their current compression state, click
  Apply changes to this folder only , and then click OK .

NTFS compression

I bought ASUS E200H: Win 10 Home; 32GB of SSD (the operating system occupies around 20GB, so only around 10GB is left for me).

After installing all the programs that I need, I had around 1GB of free space.

I was advised to perform the NTFS compression on the whole C:.

So I checked the NTFS compression fir C:, and it started to run.

As it ran, I noticed that the Windows Manager says that there is less and less free space.

When it was around 200MB, i decided to stop the process, and unchecked the compression.

The process started running again, and the free space continued decreasing, and soon reached 0 bytes.

So the question is, what should I do now?..

Should I let the compression run to the end? Or keep it decompressed - but in this case how can I regain the free space that I had before running int this procedure?.. Or possibly compress only some folders - which yes and which no?..

Thanks in advance.
