Mass Renamer v.1.0.1b

I often face the problem when I have a directory with pictures that they are with so different and strange names, so I always wanted to have a tool with which to be able to rename them with the same starting name, and ending with a sequence number.
The other problem which I often has is that when the files with similar contents are separeted in one folder and each of them has their sequence number, they have not start with the name of directory... For example: I have pictures of Boris Vallejo in directory "Boris Vallejo", but the names of files are not in the following format "Boris Valejjo xxxx.jpg", where "xxxx" is a sequence number.

So I made this simple program to solve these problems.If You have any suggestions, mail me at :

Instructions how to use the program:

Files filter:
here You can enter any valid mask to filter the content of the current selected folder.

Select All button:
by pressing it, all the files in the file view will be selected.

Base name:
here You should input the string with which You want Your files to start after manipulation.
for example: Boris Vallejo_
This field is automaticaly filled with the name of the last selected directory.

Append string:
here is a character/string which You want to add after Base name.
By default it is a space character.

Change extensions check box:
by checking this check box You will have the possibility to enter a new file extension(enter it without the dot, ex.: "jpg", not ".jpg". This option is useful if You have files with the same extension, but written in different case, ex: file1.Jpeg; file2.jpeg; file3.JPEG, etc. So if You want to make them all xxx.jpeg, You should use this option.

Start number:
this is the number from which will start the counting of new named files

Number of digits:
here You can set the number of digits to align the sequence number. For example if You enter 3 here and You have 4 files their names will be:
 file 001.jpg
 file 002.jpg
 file 003.jpg
 file 004.jpg
This is for good sort order than in Windows Explorer because it sorts files like that:
 file1.jpg
 file10.jpg
 file2.jpg .... etc.

Step:
if You enter a number different from 1, for example 3 the file names will be:
 file 000.jpg
 file 003.jpg
 file 006.jpg ... etc.

Preview button:
It simulates how will be the names of the files and show result in the Preview text box. IT NOT REALLY renames the files.

Apply button:
It renames the files with the entered new properties.
note: this action cannot be undone !!!
