Introduction
There are two ways to rename your image files in PMIO:
- Rename - Allows you to rename image files manually.
- Sequential Rename - Allows you to rename image files automatically.
Rename
To rename one or more image files manually, perform the following steps:
- Select the thumbnails of the images that you want to rename.
- Choose Rename (Ctrl/R) from the Image menu.
The following window will be displayed for each of the selected images:
Type in a new name and click Rename. It is not possible to change the file extension. If the file name you have typed already exists, the Rename button will be greyed out and a warning message will be displayed.
Sequential Rename
To rename several image files automatically, perform the following steps:
- Select the thumbnails of the images that you want to rename.
- Choose Sequential Rename (Ctrl/Q) from the Image menu.
The following window will be displayed:
Numeric
Notice that the Numeric tab is selected. This will perform a numeric rename, numbering your image files in a sequence.
- If you want to add a common prefix to the file names, type it into the Prefix box. You can use the location name as the prefix by clicking the
button. - Check the Lowercase extension box to force the file names to have a lowercase extension.
- Set the Field width to your desired value. This controls the number of digits in the file name, padded with leading zeroes.
- Set the Start at value. This controls the starting number.
- Set the Step by value. This is the 'increment' value which is added to the number. It is usually 1. You can use a negative value to number the files in descending order.
De-web
Sometimes, files downloaded from the Internet have unpleasant names such as my%2Epic[1].jpg. You can make more sensible names by using the de-web function. To do this, click the De-web tab. The window will change to this:
- Check Convert % codes to convert things like %20 to their respective ASCII characters. For example, %20 represents a space, %2E is a period. If the character is not allowed in Windows file names, it will be replaced with an underscore (_).
- Check Remove brackets to get rid of the bracketed numbers that some web browsers like to add to file names when you drag images from a web page to the desktop.
Preview
The list on the right of the window shows the old and new file names. You can use this to check the names before committing to the rename operation. If you see a 
symbol in this window, it means that there is a conflict; one or more of the new file names already exist. You need to correct this before you can continue. Once you are satisfied that the program is going to do what you want, click Rename All. Warning: The rename operation cannot be cancelled or undone.
Two-pass operation
The renaming process proceeds in two phases. First, the files are renamed to temporary names, and then they are renamed to the real target names. This prevents problems that can arise when two target file names 'overlap' (see below).
Name swapping like this requires two-pass renaming
