Bitlocker folder size

Bitlocker folder size

Bitlocker folder size


I'm not sure if this is the proper forum or not.
If anyone knows of a better forum for this question, please let me know.

I have a series of folders.
While looking at the properties of the root folder:
Size: 75.3 GB
Size On Disk: 76.8

When I moved this folder to an external drive encrypted with Bitlocker, the size on disk almost quadrupled.
Size on Disk: 405 GB.

I haven't had anything set to use bitlocker before.
Is this normal for bitlocker to increase the size so much?

I can understand some differences because of the encryption, although it seems really high.

The size, number of files and number of folders is the same between both drives. Only the size on disk was affected and essentially taking up a huge amount of disk space.

RE: Bitlocker folder size

I wonder if it is something related to 32/64 bit encryption. I'm marking the thread as I want to know as well.

RE: Bitlocker folder size

No, it is not normal. A drive with Bitlocker enabled should not have any effect on file size.

What is the total size (capacity) of the external drive?
When you copy other folders/files over, do they exhibit the same issue?
Out of curiosity, what kind of data is being stored in this folder you're having issues with?
