The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Batch file to rename all files to name of parent directory keeping extension

Zones: MS DOS, Windows Batch Scripting

Tags: microsoft, MSDOS

Hi Experts

I am trying to create a batch file to do the following:

With a given drive letter, go through all subdirectories and look in each directory.
If a file with extension .rpt exists, rename it to the same as the parent directory but maintain the .rpt extension.
The caveat is, in some directories there may be 2 files with that extension. If there are 2 I would want them renaming: <dirname_1).rpt and <dirname_2>.rpt.
e.g. 2 subdirectories in E:\ are "20080228" and "20082702". The 1st has a file within that directory called 12345.rpt. The 2nd has 2 files 23456.rpt and 34567.rpt.
The end result would be have the file in the 1st end up as 20080228.rpt, and the 2 files in the 2nd end up as 20082702_1.rpt and 20082702_2.rpt.

As there are only 7 or so main directories (with up to 100 sub dirs) this can also be done by main dir as opposed to by drive letter if any easier.

Any suggestions gratefully received as I am struggling with this.
(Running on Winxp Pro if relevant).

Thanks

Nick

I think this can only be done with some VB Script. Batch command syntax is way too primitive to do something like that without being a wizard.

A doddle for batch scripting. Can you create a quick zip of the sort of thing you have for testing.

RQuadling - this is fantastic and works 100% with the info I gave.
However, I failed to mention (sorry) that some of the directory names have a time extension (if created twice in a day for example) and could be of the format 20080229.1200
In this case, the batch drops everything after the "."

Is it possible to alter this to take this into account?

Many thanks for your "wizardry".

Fantastic. Points are yours with a much deserved A grade.

This solution will also be very useful in something else.
Rather than "bleed" from this question, I have opened another here:

Hopefully you can get to it .......
