Windows 10: Windows 10 NTFS Compression

Hi, I have a single file which is 1.6Tb terabites in size. I've click the properties and in advanced attributes I ticked "compress contents to save disk space" then suddenly hang/freeze. I decided to cancel and restart my pc. After rebooting I noticed that the file has now a two blue arrow in the icons. I opened the file but now become corrupted. I tried tlto unticked the "compress contents to save disk space" and applied. But nothing happens, after going back to properties, the "check" in the box is still there even if I already unticked it. The two blue arrow in the icon were also present. Is there any fix for this issue? I hope somebody will help me with my problem. Thank you

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.

 

NTFS Compression on Event Logs

Anyone ever try doing NTFS compression on their Error Logs?
It's all text, so it should compress pretty well.






Anyone else try this? I suppose it's only useful in server-land when you have huge event logs..

To compress:
Run services.msc
Find Event Log and set to "Disabled"
Reboot
Go to c:\windows\system32\config
NTFS Compress anything that ends in .evt
Run services.msc
Find Event Log and set to "Automatic"
Reboot

 

Is NTFS Compression really on-the-fly?

I was wondering this, but couldn't get a definitive answer. I thought about it, i use NTFS on all USB drives anyway so i can fit 4GB+ files on them and multimedia devices support NTFS anyway. So when possible, it would make more space available on USB. However, when you write data to USB thumb drive, is data copied uncompressed to the drive and then compressed (transparent, but not truly on-the-fly) or is it compressed in memory during transition itself and stored directly in a compressed form (truly on-the-fly).

Because if it's not done in memory, you're actually doing more writes than you would without compressing. But if it does compress in memory during transit, it would save a bit of a data and also make less wear.

I was also checking MS docs and it just descibes what NTSF compression does and how (algorithms and how it applies it to files), but they don't explain how it's done on a file systam scale ie, the thing i'm asking about.
