If you saved your  *.txt file as "tab Separated"  file. Make a datastore from this file and you can access any time to your datastore.  (ImportFile function for *.Txt file). The count of your datastore columns must be equal to the *.txt file columns.

Hi Bhatti,

No I won't be reading the file, I mean the contents. I just wants to know the last edited date and time of the file.
What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Try with API/SDK functions to find data and time of file attributes.

If you have worked with API's before you wouldn't find any problems with that.

You need to use 2 API's:

BOOL GetFileTime(
  HANDLE hFile,                 // handle to file
  LPFILETIME lpCreationTime,    // creation time
  LPFILETIME lpLastAccessTime,  // last access time
  LPFILETIME lpLastWriteTime    // last write time

BOOL FileTimeToSystemTime(
  CONST FILETIME *lpFileTime,  // file time to convert
  LPSYSTEMTIME lpSystemTime    // receives system time
And for working with them you need this previus created structures:

     long v_lowdatetime
     long v_highdatetime
     int v_year
     int v_month
     int v_dayofweek
     int v_day
     int v_hour
     int v_minute
     int v_second
     int v_millisecond
And the script would look like:

string filename
long   fileid

st_filetime   creationtime, lastaccesstime, lastwritetime
st_systemtime systemtime

filename = "c:\testfile.txt"
fileid   = fileopen(filename)

getfiletime(fileid, creationtime, lastaccesstime, lastwritetime)

filetimetosystemtime(creationtime, systemtime)

And voila, you have in systemtime.v_year, systemtime.v_month, and so on. Of course several error filters should help too, but this isbasically what you need to know.

Good luck.
