How to rename the file with file size

[itkesavan]

Pleas help me with the command for renameing the file using file size (note: i want to skip the 0KB file).

[foxidrive]

Supply some more information.

Is this in a single folder, or a tree of folders?
Do you want "abc & def.jpg" to become "1,456,213.jpg" ?

Pleas help me with the command for renameing the file using file size (note: i want to skip the 0KB file).

If I understood you correctly, this is what you're looking for. This will rename all the files that are larger than 0 bytes.

for /R %t in (*.*) do if %~zt neq 0 ren "%t" new.*
pause

Or using a batch file:

@echo off
for /R %%t in (*.*) do if %%~zt neq 0 ren "%%t" new.*
echo.
echo.
echo   Done!
pause

/R switch is only necessary if you need to do this recursively. Of course, you can change the renaming to something other than "new", and the extension type instead of all extensions.

got the logic. files are there in same folder. help in the below with proper code please using the file name and folder name where i have to give what

file available at d:\test folder,  filename abc*.txt (total 2 file) in this one will be 0KB.

[itkesavan]

not home work needs to do it where i have similar problem where need to do daily...

[itkesavan]

any help on this need it urgently... pls

[foxidrive]

I asked a question on how you want the files named (and Night has provided you with an almost complete solution - it needs the filename format implemented).

Your description is not clear.

[itkesavan]

I got what night has said but i dont know where to give the folder location and file name

just tell you what i want

I have file in D:\test folder, inside this folder there are soo meny files, from that i have to rename abc*.txt (total 2 file) in this one file will be 0KB. so the script needs to skip the 0kb file and rename only the file which has data. hope now you got my request. please help me with clear batch script because the script which night has given in that i dont know where to give floder location and file name.

Thanks in advance

A big part of solving a problem is being able to describe how a solution would be found. That is way in the old school you would make a sketch of a logical sires of steps that would define the solution. After having made a concise logical outline. the coding becomes easy.

I don't think you are reading the replies.  If you look at different command's help menus you should be able to figure this out.  To see the help menus you need to type the command (Most listed in the 'help' command) with a "/?" following.  You will want to look up 'for','if','ren','dir'.  I have full faith in your ability to read and comprehend these commands.  I wish you luck, but know that the members of this forum do not read minds and cannot understand what you want without you asking.

[foxidrive]

This command line based on Night's code should work.

for %t in (d:\temp\abc*.txt) do if %~zt neq 0 ren "%t" "new name%~xt"

Please provide a good explanation in future and people might be more inclined to help.
If you look at your subject line and first post it looks like you want to rename filenames with the filesize.

Stop repeating yourself...
It appears you aren't learning...and just want someone else to do it for you.

[itkesavan]

I am learning only.... when i tried with the solution i m not getting it, so only i m asking help....

FOR /R [[drive:]path] %variable IN (set) DO command [command-parameters]

learning now only basics....

Did you see my comment above? 
English may not be your first language but if you don't understand something then ask for clarification and mention which part you don't understand.

When a batch file doesn't perform as you expect, then describe what happened and what error messages occurred.  Help us to help you, and be interactive.

@echo off
D:
cd temp
for /R %%t in (D:\temp\abc*.txt) do if %%~zt neq 0 ren "%%t" "new name%~xt"
echo.
echo   Done!
pause

i need a clarification on the am i missed anything in it. because when I execute noting is happening no error message also.
can you correct me on the above where i am wrong

[Salmon Trout]

"new name%~xt"

Something wrong here

Also after you have fixed that, if there is more than one file in d:\temp that satisfies abc*.txt, only the first will get renamed (to new name.txt), all the others will not be be renamed, and the script will halt at the first such and give an an error message:

A duplicate file name exists, or the file
cannot be found.

[itkesavan]

yes there are 2 files in it, on that on is 0 KB. the script wat have not renames only the 0 KB file first so that only i m asking help to rename the file with file size so i can skip the 0KB file. but the above script not working pls provide any script or if any correction pls tell me....

[Night]

Yeah, I wasn't sure what he was trying to say so I gave him a possible solution.

[patio]

Yeah, I wasn't sure what he was trying to say so I gave him a possible solution.

 HuHH ? ?
And how exactly did you do that ? ?

[itkesavan]

Any correction needs to be do on the below. because it is not working.

@echo off
D:
cd temp
for /R %%t in (D:\temp\abc*.txt) do if %%~zt neq 0 ren "%%t" "new name%~xt"
echo.
echo   Done!
pause

One of your % signs is not doubled.

A good way to debug is to remove '@echo off', and see what actually is being run.

[itkesavan]

after i remove @echo off
alos it is not showing any error. Please help me with it.

[foxidrive]

I posted some time back

One of your % signs is not doubled.

Did you fix that?
