Hi All,
I have written a small program to find the size of folder's ,
but the output is not as expected, hence request your help and
advice on any techniques to reduce the run time of the program.
Requirement:
The script has to scan several file system
("C:\\Temp\\TEAM","C:\\Temp\\PROD_TEAM", "C:\\Temp\\BACKUP")
Display only the sub folder level 1 name whose name should not
contain *DND* and size
dirEntries(i, SpanMode.shallow).filter!(a => a.isDir &&
!globMatch(a.baseName, "*DND*"))
Eg: C:\Temp\TEAM\USER_BACKUP , C:\Temp\PROD_TEAM\PROD_BACKUP ,
C:\Temp\BACKUP\SUPPORT_BACKUP
Need the folder name and size of each folder under
C:\Temp\TEAM\USER_BACKUP , C:\Temp\PROD_TEAM\PROD_BACKUP ,
C:\Temp\BACKUP\SUPPORT_BACKUP

Program
--------
import std.file: dirEntries, isFile, SpanMode;
import std.stdio: writeln;
import std.algorithm: filter;
import std.array: array;
import std.path;
auto AgedDirlst = [ "C:\\Temp\\TEAM\\USER_BACKUP" ,
"C:\\Temp\\PROD_TEAM\\PROD_BACKUP" ,
"C:\\Temp\\BACKUP\\SUPPORT_BACKUP" ];
void main ()
{
foreach (string i; AgedDirlst[0 .. $])
{
auto dFiles = dirEntries(i, SpanMode.shallow).filter!(a =>
a.isDir && !globMatch(a.baseName, "*DND*")).array;
foreach (d; dFiles)
{
auto SdFiles = dirEntries(d, SpanMode.depth).array;
foreach (f; SdFiles)
writeln(f.dirName, "\t", f.size);
}
}
writeln("*************************************************************************************");

Keep a variable to add the sizes of subdirs
auto dFiles = dirEntries(i, SpanMode.shallow).filter!(a =>
a.isDir && !globMatch(a.baseName, "*DND*")).array;
ulong subdirTotal = 0;
foreach (d; dFiles)
{
subdirTotal = 0;
auto SdFiles = dirEntries(d, SpanMode.depth).array;
foreach(f; SdFiles) {
subdirTotal += f.size;
}
writeln(d, "\t", subdirTotal);
}
