Hi all,

Can anyone suggest me whether its possible to write a batch to check whether a file is completely written or in the process of writing. filecheck.bat path\filename should tell whether that file is completely written or in progress.

Thanks in advanceI am unsure if this is possible in batch, but I know I could definitely do it in VB. If you want me to build it for you, feel free to PM me.Yes it is possible. You cannot rename a file which is in USE by another process, so all you have to do is test if the file exists and then ATTEMPT to rename the file to a dummy name (which does not exist). If the errorlevel is greater than 0 then the file is in use by another process and you cannot rename it. If the errorlevel is zero then the rename succeeded so you rename it back again to its real name. Of course we assume that other sources of error are taken care of e.g. read-only medium, dummy file already exists, etc.




Thanks both.

Bob can u help me in PROVIDING the vb script.

To clarify, I spoke of Visual Basic, not the Scripting variant of such. I could certainly help you if you wish. I just need about three days, because I don't have constant computer access.batch

Code: [Select]echo off
echo Testing file %~nx1
if not exist "%~dpnx1" echo File does not exist! & goto END
if exist "%~dp1\dummy.file" del "%~dp1\dummy.file"
ren "%~dpnx1" dummy.file
If %Errorlevel% gtr 0 (
echo file in use
) else (
echo file not in use
ren "%~dp1\dummy.file" "%~nx1"
)
:end
VBscript

Code: [Select]filespec=wscript.arguments(0)
set fso=createobject("scripting.filesystemobject")
on error resume next
if not fso.fileexists(filespec) then
    wscript.echo "File does not exist!"
    set fso=nothing : wscript.quit(1)
end if

wscript.echo "Testing file " & Filespec
set ots=fso.opentextfile(filespec,8,false)    'forappending
if err.number<>0 then
     wscript.echo "file in use" : err.clear
else
    wscript.echo "file not in use"
    ots.close
end if
on error goto 0
set ots=nothing : set fso=nothing
Never mind VB. Thank you, Salmon Trout.Thanks salman trout.I am thinking you could probably do this also with the OPENFILES command or the HANDLE Utility.
