Correcting Date Tags, Renaming, Reorganizing to Subfolders

[borapoyraz]

First of all I have been reading this forum almost for six hours and it was very useful. But i couldn't find the information which can solve my issue.

I'm very new of using ExifTool, I tried using some softwares instead of it first because i'm not good at writing command lines but they didn't seem good and effective as much as ExifTool so i decided to learn it but I couldn't succeed it.

Accidently i mixed my photos and videos in different folders.(More than 10 different extensions) So i only have date informations to reorganize them. First i categorized them using their extensions.



My aim is:
1) giving correct date info to every date tags (as much as i can, because i might have some missing or wrong date tag infos)
2) reorganize them to subfolders that have name as "year/year-month/year-month-date"

As an example(it's my example because i couldn't succeed to change date tag), i have a one *.mov file with three different dates.



As i see, "date taken" info is wrong. "File Modification Date" seems to be correct so i tried to check all other date tags if they were same with "File Modification Date" or not.

I found this.



Most of them are same with "File Modification Date" but still I have some false date tags (like "File Creation Date" or "Date Taken")
I want to correct all of them so,

When i compared first and third images, I never find wrong "Date Taken" tag with ExifTool (which is 16.07.2015 )
because of not finding it, i can't correct it with ExifTool as well.

My questions are these.

1) Is "Date Taken" important? if it is, what can i do to find and change it with appropriate tag? (what is the proper tag to change and what is the command line?)
2) If it is not important, which date tag is most appropriate to use for giving all other tags? (and what is the command line?)
3) If I succeeded giving them correct date tags, how can i rename them by using date tag and how can i reorganize them to subfolders by using date again as well? (what command or commands should I use?)

And if I need to use different command lines for different extensions (*.MOV *.JPG *.JPEG *.3GP etc.) What different commands should I use ? or Is there any common command for them?

Also I need commands to use multiple files.

I may have given missing or wrong information please if you don't understand ask me again 

Thanks in advance.

See this post by StarGeek for details about what tags are displayed by Windows.

I can't answer the question about importance, but I would think it would be nice to get this right because it is displayed by Windows.

2) If it is not important, which date tag is most appropriate to use for giving all other tags? (and what is the command line?)

This depends on the file type.  For JPEG images, DateTimeOriginal is probably the most often used.  For MOV/MP4 videos, CreateDate.

3) If I succeeded giving them correct date tags, how can i rename them by using date tag and how can i reorganize them to subfolders by using date again as well? (what command or commands should I use?)

See this page for help and examples with this.

And if I need to use different command lines for different extensions (*.MOV *.JPG *.JPEG *.3GP etc.) What different commands should I use ? or Is there any common command for them?

You can use one command for all, but you may have to add additional arguments to use CreateDate if DateTimeOriginal isn't available for example.  Plus you may have to add -ext options to specify the extensions you want to write.

Also I need commands to use multiple files.

Just specify the directory name and exiftool will process all files in the directory.  Add -r to recurse through subdirectories.

Unfortunately, a lot of the filetypes in borapoyraz's listing aren't listed in that link.  It would take some more research to deal with them.

I still can't figure it out how to access and change wrong "Date Taken" which is shown by Windows as 16.07.2015 00:48 for *.MOV file with ExifTool.

or is it possible to access and change "Date Taken" which is shown by Windows with ExifTool.

StarGeek's infos are only about JPEG and other image files as i see.
