Java File Bulk Rename batch fetch specific type file _java

Reason:

Because in the online download video tutorials, some names are particularly long, is generally the organization or website propaganda, not convenient to see the video of the introduction, so did the following first function.

Because the teacher sends the courseware, the folder is too many, wants to put the docx all to put in the same folder below, one one finds to be too troublesome, therefore has done the second function.

Recently learned the Java file and flow of knowledge, so just practicing practicing, this is their first EXE program, share AH.

(Export jar file, and use tool exe4j to generate EXE file, this part omitted ha)

The knowledge used:

Use Java files, streaming knowledge, and simple GUI knowledge.

Function:

Function One: Remove the name of some of the keywords, can also be set to replace the word.

Function Two: Extract a path under all the specific types of files, and then put it under a new folder, if there are duplicate files, then automatically sorted by adding numbers to differentiate.

First look at the start of the interface and the resulting EXE file:

First Feature Demo:

Not before the operation:

After the operation: the previous part of the same keyword all removed

Also has the recall function:

A second feature demo:

No action before:

After Operation:

Of course, there is also a recall function
