For example: If there are the following files under a folder (the folder name is known as asd, and there are many files in the folder, which cannot be listed manually):

Volume in drive D is WINDOWS
Volume Serial Number is E42C-4D75

Directory of D:\asd\asd

2006-10-24 17:47 <DIR> ..
2006-10-24 17:47 <DIR> .
2006-10-20 11:47 1,226 tftp.txt
2006-10-16 15:51 2,306 ftp1 server.txt
2006-10-16 15:51 2,306 ftp1.txt
2006-10-16 15:51 2,306 ftp2.txt
2006-10-16 15:51 2,306 ftp3.txt
2006-10-16 15:51 2,306 ftp1.rar
2006-10-16 15:51 2,306 ftp1.log
2006-10-16 15:51 2,306 ftp2 server.txt
2006-10-20 14:30 10,752 ftp1.doc
9 File(s) 28,120 bytes
2 Dir(s) 12,679,954,432 bytes free

How to delete files with the same size and the same file type???
(That is to say, the three files ftp2.txt, ftp3.txt, and ftp2 server.txt need to be deleted,)

I remember there was a small thing that could be directly deleted, est posted about it

```
for /f "delims=" %a in ('dir /a ^| find "2,306"') do @del %a
```

The owner wants to delete all files with the same size and type, or keep one and delete the others?

Keep one. Delete other files that have the same size "and" also the same type as this one.

What the 4th floor provided does not meet the requirements

After confirming it is correct, change echo %a to del %a

What I mean is: First, we don't know how many files are in the folder (because there are too many to list manually), and we don't know the size of the files. We only know the name and path of the folder. The above is a simple example. Actually, there are many files (mainly.doc,.xls files, too many to list here), and there are many files with similar names and the same size that are actually the same. So we need to delete them to save space.
Hope electronixtar can help improve it again. By the way, can batch processing achieve fuzzy matching, for example: delete (temp1.doc, temp2.doc, temp3.doc, temp4.doc~~) and keep temp1.doc by keeping temp2~~.doc.
Note: temp is just a placeholder for the files to be processed.

It's very simple, copy out temp1.doc and delete the folder.

So depressed!
But I guess that's how scholarship is!

What I mean is I know the name of this folder, but I don't know the names of the files in the folder (so the above temp is just a placeholder,...... a placeholder. Not actual). Because there are too many files, I can't list them one by one.
For example for example for example for example:
There are temp1.doc, temp2.doc, temp3.doc~~
tmp1.xls, tmp2.xls, tmp3.xls~~
study1.txt, study2.txt~~
***1.gif, ***2.gif~~~~

So the function of dir also needs to be implemented in del.bat, and also find (***) then perform the function of deleting duplicate files. I don't know if electronixtar understands. Oh my expression ability, so...... hahaha. electronixtar needs to carefully figure out my meaning. Thanks.

If this operation is only done once, you can complete it through Windows' search function, heh heh~

Hahaha, I spent the whole morning looking at everything related to deletion. It doesn't seem to fit my conditions.

That was he200377 who misread it. I also thought it was a really stubborn duplicate file when I saw the title of the original poster, but it turned out to be a duplicate file. Hehe

This question is a bit difficult

If you want to delete duplicate file contents, it's not easy.

No, I need to repeat it many times. There are too many, so I want to write a batch script to do it. I'm not very capable myself, so I'm here to ask for help from all the experts. Hahaha

Remember a software called: Duplicate File Finder
