Hi,

   The above program scan for files/directories under the main 
folder N:\PROD_TEAM\ and reports the size of each of the sub 
folders eg: "TST_BACKUP", under the main folder "N:\PROD_TEAM\" 
there are more than 9000+ files/directories, eg: 
(N:\PROD_TEAM\TST_BACKUP,N:\PROD_TEAM\PRD_BACKUP\....)  and the 
above program will output the size of the sub folders 
"TST_BACKUP,PRD_BACKUP",  there is no issue is the path is 
shorter, the issue arises only when the path is bigger, eg the 
program prints the size of the sub folder PRD_BACKUP but when it 
tries to scan the sub folder TST_BACKUP the issue arises and the 
program terminates with the exception "The system cannot find the 
path specified", hence it not not be possible to provide the path 
explicitly, so can you help me on this.

From,
