All file systems supported by Windows use the concept of files and directories to access data stored on a disk or device. Windows developers working with the Windows APIs for file and device I/O should understand the various rules, conventions, and limitations of names for files and directories.
Both Key and Allen say the typical yard they deal with is about a quarter-acre in size and the sprinkler systems cost about $2,500 to $3,500 to install. Allen says the cost to install sprinklers on half-acre lawns runs $3,500 to $5,500, and one-acre properties cost $6,000 to $8,000.
Length of drip line? I am planning a sprinkler system in a new yard. I used Toro's design service (and was very impressed). Anyways, the plan calls for only one riser for the drip system (servicing all of the flower beds). The total amount of drip line (1/2) in the yard will be close to 900 feet!!
