this<\/I> Scripting Guy, though (or at least not on this one occasion). Instead, he used a script very similar to this one to rename his picture files:<\/P>strComputer = “.”<\/p>\nSet objWMIService = GetObject(“winmgmts:\\\\” & strComputer & “\\root\\cimv2”)<\/p>\n
Set colFiles = objWMIService.ExecQuery _\n (“ASSOCIATORS OF {Win32_Directory.Name=’C:\\Photos’} Where ” _\n & “ResultClass = CIM_DataFile”)<\/p>\n
For Each objFile In colFiles\n strEnd = Right(objFile.Name, 8)\n strNewName = objFile.Drive & objFile.Path & “272_DSC_” & strEnd\n errResult = objFile.Rename(strNewName)\nNext\n<\/PRE>\n
A couple things to note here. First, we\u2019re assuming that you want to rename all<\/I> the files in a particular folder. If that\u2019s not the case, then you\u2019ll have to include additional code to filter out files that shouldn\u2019t be renamed. Second, we\u2019re assuming that each photo ends with four digits and a .jpg<\/B> file extension. If that\u2019s not true, (for example, if you have files with names like _JKG1.jpg), well, then this particular script won\u2019t help you. You can still rename files that have names like that, but the code is a bit more complicated. But seeing as how all the digital cameras we\u2019re familiar with tack a four-digit number at the end of the file name, we\u2019ll assume that\u2019s true in your case as well.<\/P>\n
The script begins by connecting to the WMI service on the local computer, then uses an Associators Of<\/B> query to return a collection of all the files in the folder C:\\Photos:<\/P>Set colFiles = objWMIService.ExecQuery _\n (“ASSOCIATORS OF {Win32_Directory.Name=’C:\\Photos’} Where ” _\n & “ResultClass = CIM_DataFile”)\n<\/PRE>\nAdmittedly, an Associators Of query is weird-looking. But don\u2019t worry about that; instead, just replace C:\\Photos with the path to your picture files and leave everything else alone.<\/P>\n
We then use this block of code to walk through the collection of picture files:<\/P>
For Each objFile In colFiles\n strEnd = Right(objFile.Name, 8)\n strNewName = objFile.Drive & objFile.Path & “272_DSC_” & strEnd\n errResult = objFile.Rename(strNewName)\nNext\n<\/PRE>\nInside the loop we take a look at the Name<\/B> of the first file; that\u2019s going to be something like C:\\Photos\\_JKG1234.jpg. (In WMI, the Name property of a file is what we would call the file path.) We then use the VBScript Right<\/B> function to grab the rightmost eight characters in the Name; in this case, that will be 1234.jpg (C:\\Photos\\_JKG1234.jpg<\/B>). Those are eight characters we want to preserve (we don\u2019t want to change the numbering or the file extension), so we stash them in a variable named strEnd.<\/P>\n
Next we construct a new name for our file; that\u2019s what we do here:<\/P>
strNewName = objFile.Drive & objFile.Path & “272_DSC_” & strEnd\n<\/PRE>\nWhen you rename a file using WMI you need to specify the complete file path; you can\u2019t just rename a file something like NewName.jpg. Because of that we need to concatenate the drive letter for the file (C:), the path (in WMI terms, the folder path without the drive letter, or \\Photos\\), the new file name prefix (272_DSC_), and the eight characters we preserved from the existing file name. In other words:<\/P>
C: + \\Photos\\ + 272_DSC_ + 1234.jpg\n<\/PRE>\nPut them all together and they spell C:\\Photos\\272_DSC_1234.jpg<\/B>. And that\u2019s good, because that\u2019s exactly what we want the new file path to be.<\/P>\n
From there we simply call the Rename<\/B> method, passing the new file path as the sole method parameter. We then loop around and repeat the process for the remaining files in the collection.<\/P>\n
And you know what, NA? We agree with you: knowledge like this is far<\/I> more valuable than a winning lottery ticket. Just keep telling yourself that: far more valuable. <\/P><\/p>\n","protected":false},"excerpt":{"rendered":"
