@FileSize - How is this possible?

[mathewsdw]

As usual a quick screen shot:

[Z:\]echo %@Comma[%@Eval[%@FileSize[C:\,b,a]-%@FileSize[C:\,b]]]
-4,294,936,837

The question should be obvious: How can the allocated size be less than the file size? What am I missing?

​

 

[rconn]

You're not providing a file name, you're entering a directory name (which will return "-1" because it's not a file).

 

[mathewsdw]

Beg to differ, Rex. Behold:

[C:\]echo %@Comma[%@FIleSize[C:\,b,a]]
5,011,992,576

[C:\]echo %@Comma[%@FIleSize[C:\*,b,a]]
5,011,992,576

[C:\]echo %@Comma[%@FIleSize[C:\,b]]
9,306,929,413

[C:\]echo %@Comma[%@FIleSize[C:\*,b]]
9,306,929,413

Need I say more?

If it makes any difference I am running TCC 16.03.55 x64 Windows 7 [Version 6.1.7601].

Show us the results of this.

echo %@FileSize[C:\,b,a]^r^n%@FileSize[C:\,b] & *dir c:\

 

[vefatica]

You're not providing a file name, you're entering a directory name (which will return "-1" because it's not a file).

The '*' seems to be implied.

v:\> echo %@Comma[%@Eval[%@FileSize[C:\*,b,a]-%@FileSize[C:\*,b]]]
8,158

v:\> echo %@Comma[%@Eval[%@FileSize[C:\,b,a]-%@FileSize[C:\,b]]]
8,158

Here it be:

Note again that the allocated size is less than the size.

 

[rconn]

Are you running with NTFS disk compression enabled?

 

[mathewsdw]

Not as far as I know unless it was turned on at the factory (this is a new machine). How can I tell?

 

[mathewsdw]

A quick Google search told me how to find out (of course) and the answer is no. See attached screen shot.

 

[rconn]

Do a "DIR /C C:\".

 

[mathewsdw]

That is the answer, Rex. The RAM disk software I am using evidently compresses its on-disk image(s). Look at the RAMDisk.img files at the bottom of the below (I can't highlight them in a code block).
