RE: Determining File Size

Subbu, thanks for the hint to look for the directoryEntry.

I have working code (see example).
When I inspect aFile then the other variables are there (for instance, there is a creationTime which contains a number, and there is a fileSize).
But the fileSize = 0.

1. What is going wrong with the fileSize, because the file is much bigger than 0!

2. How can I change creationTime to something readable? Now it is a LargePositiveInteger, not very useful to display.

| aFileDir aFile |

    aFileDir := (FileDirectory default directoryNamed: 'mytestdir').
    aFile := aFileDir directoryEntryFor: 'my test file.mp3'.
    Transcript cr;show: aFile creationTime printString.
    Transcript cr;show: aFile fileSize printString.

Regards,
Van.

Hi,

I'm listing files in a directory, but I want to show more than just the
filename (like file size and may be creation date). I've searched for some
time on the Internet, but I can't find the answer. How to do this?

I've tried this:
aFile := (FileDirectory default directoryNamed: directoryName)
assureExistence;
readOnlyFileNamed: 'testfile.pdf'.
and then tried: aFile size but that doesn't seem to work.

Regards,
Van.

File size is an attribute of the file's entry in its directory.

See fileSize method in DirectoryEntry class. If you already have a file handle
or a stream opened on it, use directoryEntry method. E.g.

stream directoryEntry fileSize

Make sure the file exists! Try inspecting each line in the workspace to see if
you are using the right path elements.

Time fromSeconds: self creationTime.
or
Date fromSeconds: self creationTime.

will convert time from epoch counts to d/m/y, h:m:s forms.
