Clear Hard Drive Space Automatically

Hadez · November 1, 2010

Im working on a script that will auto delete files when the hdd space on the drive gets below 10gb.Once if sees that the free hdd space falls below 10gb, The script will check the folder i want it to delete files from, check the creation date of each file and if the file is over 5 days old, then delete it.

Im having some problems with the checking of files. Can anyone give some guidance?

ive sort of got the search function for the files i want to delete, and ive got the date i want to delete the fiels that were created early than but am strugglin to join the two. Any help would be appreciated. So in summary:

Drive space will be watched

If Free Drive space goes below 10gb, the folder D:\Files\ is searched

All files in D:\Files\ that are older than 5 days old are deleted

Process is looped.

I'm too tired to integrate it into what you already have, but give this function a try, making sure you keep the '#include <Date.au3>' in the script. If you call this function, it'll start the search, compare each file date to the current date on the fly, and if it's 5 days or older, delete it. Certainly play around with it and add your memo write where needed, but I think this should do the trick for ya. The key was all in the _DateDiff function, and once I figured out how to use it it worked great. You can fine tune it by searching by days, hours or even minutes if you want. Looks like all you need to do is have it call on this when the HD size is down to the trigger size. If you want it to only keep going until you free up enough space, I would look into adding an if statement at the end of the while loop that checks the HD space again (at that point I'd make it a function); once it gets to y size, exit loop.

Hope this helps.

Func _deleteOld()
$dir = "D:\Files\"

$search = FileFindFirstFile($dir & "*.*") ; get all files from the directory

If $search = -1 Then ; return an error if the search fails
    MsgBox(0, "Error", "No files found in the search")
    Exit
EndIf

While 1
    $file = FileFindNextFile($search)
    If @error Then ExitLoop
    $t =  FileGetTime($dir & $file, 1) ; Pulls the file creation time into an array, use 0 for a string
    $tformatted = $t[0] & "/" &  $t[1] & "/" & $t[2] & " " & $t[3] & ":" & $t[4] & ":" & $t[5] ; Formatted to work with _DateDiff
    $iDateCalc = _DateDiff( 'D', $tformatted,_NowCalc()) ;throws the difference of the time in Days into the variable
    if $iDateCalc > 4 Then filedelete($dir & $file) ;If the value, returned in days, is greater than 4 (5 or higher) delete the file
WEnd

FileClose($search)

Have a read of the comments. I suspect it is something simple
