finding path and timestamp of file used

Hi All,

I am reading data into dataset with rawData = dataset('XLSFile','myData.csv', 'sheet','myData');

I want to collect entire file path with timestamp so that i can later print it as report for all input files like this.

How do i do it?

I am using following to get the path now, just figured.

 a = (fileparts(which('myData.csv')));
 b = [a, '\', 'myData.csv'];
 rawData = dataset('XLSFile','myData.csv', 'sheet','myData');

That gets me the path of the file and I make sure my file being read from that path. But how do i get time stamp?

Try this:

filename = which(mfilename('fullpath')) % Whatever you need.
fileInfo = dir(filename)
fprintf('The date of %s\nis %s\n', filename, fileInfo.date);

In the command window:

filename =
C:\Users\Neesha\Documents\MATLAB\work\Tests\test1.m
fileInfo = 
       name: 'test1.m'
       date: '12-Dec-2014 15:01:02'
      bytes: 395
      isdir: 0
    datenum: 735945.625717593
The date of C:\Users\Neesha\Documents\MATLAB\work\Tests\test1.m
is 12-Dec-2014 15:01:02

there is also the datenum value you can use if you need a number instead of a string.

myFile = java.io.File( filename );

myFile.lastModified
myFile.getCanonicalPath

[Neesha]

Ok, thanks. getCanonicalPath gets me the file path. But lastModified returns zero and not the timestamp

[Adam]

strange, it works on files I have used it for.

dir( filename )

should give you a structure from which you can get the date also as a string.

[Neesha]

That is what i expected - for it to be a struct. When i do myFile = java.io.File(filename); and then type in 'myFile' on command window i expected to give me whole bunch of info instead it just prints my file name i passed.

Do i need to intiantiate Java class or something?

[Neesha]

Yes it does give me timestamp if i use it with Dir and then .date.

Weird that it does not with myFile.LastModified

[Adam]

It doesn't give a struct. Those are actually functions not properties/fields. It confused me at first but

methods( myFile )

shows you the options.
