Since there's little need to extract timeCreated and name
before sorting, here's a version that doesn't:
import std.algorithm : map, filter, sort;
import std.array : array;
import std.range : join;
import std.file : SpanMode, dirEntries, isDir;
import std.stdio : writefln;
import std.typecons : tuple;
void main() {
auto folders = [`C:\Windows`, `C:\Program Files`,
`C:\Users`];
auto sorted = folders
.map!(f => f.dirEntries(SpanMode.shallow))
.join
.filter!(e => e.isDir)
.array
.sort!((a,b) => a.timeCreated < b.timeCreated)
.map!(e => tuple(e.name, e.timeCreated.toSimpleString[0
.. 20]));
writefln("%(%-(%-63s %s %)\n%)", sorted);
}
And a version with normal loops, since the heavily range-based
version above can be a bit dense. These programs do essentially
the same thing:
import std.algorithm : sort;
import std.array : array;
import std.file : SpanMode, dirEntries, DirEntry, isDir;
import std.stdio : writefln;
import std.typecons : tuple, Tuple;
void main() {
auto folders = [`C:\Windows`, `C:\Program Files`,
`C:\Users`];
DirEntry[] subFolders;
foreach (folder; folders) {
auto children = dirEntries(folder, SpanMode.shallow);
foreach (child; children) {
if (child.isDir) subFolders ~= child;
}
}
subFolders.sort!((a,b) => a.timeCreated < b.timeCreated);
Tuple!(string, string)[] interestingParts;
foreach (subFolder; subFolders) {
interestingParts ~= tuple(subFolder.name,
subFolder.timeCreated.toSimpleString[0..20]);
}
writefln("%(%-(%-63s %s %)\n%)", interestingParts);
}
As you can see, I'm just chopping off the parts I don't like
from toSimpleString. It seems a good format function for dates
does not exist in Phobos.

Hi Biotronic,
I was able to find a solution using container array and also
date formatting, below is the code, please do let me know if you
find any issue, as i have tested the script and it is working as
expected.
Program:
import std.algorithm: filter, map, sort, each;
import std.container.array;
import std.file: SpanMode, dirEntries, isDir ;
import std.stdio: writeln,writefln;
import std.typecons: Tuple, tuple;
import std.datetime.systime: SysTime;
import std.conv;
void main () {
auto FFs = ["C:\\Temp\\sapnas2\\BACKUP",
"C:\\Temp\\sapnas2\\EXPORT"];
Array!(Tuple!(string, SysTime)) Sorted;
foreach(d; FFs[]) {
auto dFiles = Array!(Tuple!(string, SysTime))(dirEntries(d,
SpanMode.shallow).filter!(a => a.isDir).map!(a => tuple(a.name,
a.timeCreated)));
foreach(i; dFiles[]){ Sorted ~= i; }
Sorted[].sort!((a,b) => a[1] > b[1]).each!(e => writefln!"%-63s
%.20s"(e[0], e[1].to!string));
}
}
From,
