Depending on the size of the drive, you may need to divide further. The one I tested on is 2GB. ===================================== If at first you don't succeed, you're about average. M2

Hey M2, thanks for all the help, but I think I'm in over my head now. Most of the drives I'll be checking for space are 100+ gigs, and one is a RAID 5 array at about 1TB. We're adding a 3 TB NAS too, so I'll need to check that... I'm at a loss as to what the FOR loop in your example actually does, and why I'd need to divide further (right now, it's getting MB's, correct?). I haven't really worked with batch files since the early 90's, or done any programming in about 9 years. So all the new commands are a bit confusing. I understand that you're piping a Find command into the DIR of the entire drive. Apparently every time the Find finds an instance, it sets the var to %A/1 000 000. But what to the Tokens and Delims do? thanks for any help!

You can look at: for /? but the 'help' is rather tortured, as usual. "tokens=*" means 'use every chunk' and "delims=" sets the 'separator'; by default, it's SPACE/TAB. "tokens=3" means 'use the 3rd chunk'. I think you'll need to divide by 1G in stead of 1M to avoid going out of range. ===================================== If at first you don't succeed, you're about average. M2

So, should I have the FOR loop continue to divide by 1M, but add them up, then divide by 1000 to get gigs after the FOR loop?

Alright this is my current batch file: @echo off setLocal EnableDelayedExpansion echo Filetot for loop: for /f "tokens=3 delims= " %%A in ('dir /s/-c \ ^|find "File(s)"') do ( set /a fileTOT+=%%A/1000000 echo FileTot: !fileTOT! MB ) echo freespace for loop: for /f "tokens=3 delims= " %%A in ('dir /-c \ ^|find "Dir(s)"') do ( set /a freespace=%%A/1000000000 echo Free: !freespace! GB ) echo used: !fileTOT!MB echo free: !freespace!GB set /a TOTAL=!fileTOT!+!FREE! echo total disk space: !TOTAL!MB set /a pcUSED=(!fileTOT!*100)/!TOTAL! echo percent used: !pcUSED! This is the output: Filetot for loop: [...tons of lines of FileTOT adding up...] FileTot: 4290 MB FileTot: 4291 MB FileTot: 4291 MB FileTot: 4291 MB FileTot: 4292 MB FileTot: 4293 MB FileTot: 4293 MB FileTot: 4293 MB FileTot: 4293 MB Invalid number. Numbers are limited to 32-bits of precision. FileTot: 4293 MB freespace for loop: Invalid number. Numbars are limited to 32-bits of precision. Free: GB used: 4293MB free: GB Missing operand. total disk space: MB Missing operand. percent used: Okay, so apparently I hit a wall somewhere when getting the MB for Filetot, and then I hit the same wall when even just trying to divide by 1 000 000 000 to get freespace in GB. Is there any way to get DOS to use larger numbers? thanks for all the help!

Alright, I think I nailed it. Here's the output from the final batch file (pasted below). command line: tester \ Total space: 155 GB Free space: 146 GB (95%) Used space: 9 GB (5%) Check the batch file below, feel free to copy it for your own usage! Doug :: tester.bat :: 2007 Douglas Craig with massive assistance by Mechanix2Go @echo off setLocal EnableDelayedExpansion :: check for path if ()==(%1%) goto syntax :: check existence of path if not exist %1 goto badpath :: find total used space for /f "tokens=3 delims= " %%A in ('dir /s/-c %1 ^|find "File(s)"') do ( set totalused=%%A ) :: find total free space for /f "tokens=3 delims= " %%A in ('dir /-c %1 ^|find "Dir(s)"') do ( set freespace=%%A ) :: output truncated totals in temp file for use later echo.Used !totalused:~0,-9! >"testtemp.txt" echo.Free !freespace:~0,-9! >>"testtemp.txt" :: input truncated total used space from temp file for /f "tokens=2 delims= " %%A in ('type testtemp.txt ^|find "Used"') do ( set totalused=%%A ) :: input truncated free space for /f "tokens=2 delims= " %%A in ('type testtemp.txt ^|find "Free"') do ( set freespace=%%A ) :: calculate total drive space, percentage used, and percentage free set /a totalspace=!totalused!+!freespace! set /a percentused=(!totalused!*100)/!totalspace! set /a percentfree=100-!percentused! :: output results echo. echo Total space: %totalspace% GB echo Free space: %freespace% GB (%percentfree%%%) echo Used space: %totalused% GB (%percentused%%%) :: clean up temp file del testtemp.txt goto end :: syntax info :syntax echo. echo.Usage: TESTER [path] echo. echo. where [path] is a directory on drive or network path echo. echo. example: TESTER \ echo.

Hi Doug, Yep, you nailed it. Seems like youcould skip some steps and writing to file. set raw=%%A set free=!raw:~0,-9! ===================================== If at first you don't succeed, you're about average. M2

Thanks, that works. Didn't realize you had to reassign variables to get them from the FOR loop. Thanks for all the help!

I'm not a big fan of batch scripting. If you have the knowledge, I would've suggested using VBScript. You can easily get drive information (including used and free space) with the Win32_LogicalDisk WMI class. The only tiny snag is that the drives MUST be mapped in order for them to show up. But you can easily map the drives, run your calculations, and then disconnect those network drives. And from there, it's easy output to your file! IMHO, that just seems like a lot less hassle. But it all comes down to personal preference.

EDIT: That WMI class I mentioned in the previous post should actually be "Win32_MappedLogicalDisk". The Win32_LogicalDisk class shows both the physical and networked drives.

Here is another suggestion - only I'd like to get a more accurate number that "80GB" on my 80 GB drive which is in fact 74.5 gb formatted....anyway... @ECHO OFF @COLOR 7 @SETLOCAL ENABLEEXTENSIONS @SETLOCAL ENABLEDELAYEDEXPANSION @CLS @FOR /F "tokens=1-3" %%n IN ('"WMIC LOGICALDISK GET Name,Size,FreeSpace | find /i "%1""') DO @SET FreeBytes=%%n & @SET TotalBytes=%%p @SET /A TotalSpace=!TotalBytes:~0,-9! @SET /A FreeSpace=!FreeBytes:~0,-10! @SET /A TotalUsed=%TotalSpace% - %FreeSpace% @SET /A PercentUsed=(!TotalUsed!*100)/!TotalSpace! @SET /A PercentFree=100-!PercentUsed! @ECHO Total space: %TotalSpace%GB @ECHO Free space: %FreeSpace%GB @ECHO Used space: %TotalUsed%GB @ECHO Percent Used: %PercentUsed%%% @ECHO Percent Free: %PercentFree%%% @SET TotalSpace= @SET FreeSpace= @SET TotalUsed= @SET PercentUsed= @SET PercentFree= /Tipsmark
