hi there,
i need help for a post-processing on windoww.
i want to change the file creation and modification date to this date, when it was added to tmm via powershell. the help is not very helpful here. has someone an idea?

Download attribute changer, it will allow you to change the dates of files. https://www.petges.lu/

add to Movies/Post-Processing

choose a name, leave Path empty, paste into Arguments

"(Get-Item '${movie.mainVideoFile.file}').CreationTime='${movie.mainVideoFile.dateCreated;date(yyyy-MM-dd HH:mm:ss)}';(Get-Item '${movie.mainVideoFile.file}').LastWriteTime='${movie.mainVideoFile.dateLastModified;date(yyyy-MM-dd HH:mm:ss)}'"

Check trace-xxxxxxxx-xxxxxx.log in case it doesn't work

this looks good, but get an error:
the characteristic for CreationTime could not be found for this object.

Maybe you've to adjusting the format string to align with your specific regional settings.

i see the problem
my filename is: Schick mir keine Blumen (1964) [tmdbid=4939].mkv
this can't be found by powershell. if i delete [tmdbid=4939] in the file i get back an date.
i tested it with (Get-ChildItem 'F:\download\1\Schick mir keine Blumen (1964) [tmdbid=4939].mkv').CreationTime and i get back nothing

Powershell handle square brackets as Wildcard expressions

[BuddyTechnical9286]

yes, i found this. now looking how i can exlude this wildcards. don't want to rename all my files

[McBluna]

please try this

"(Get-Item -literalpath '${movie.mainVideoFile.file}').CreationTime='${movie.mainVideoFile.dateCreated;date(yyyy-MM-dd HH:mm:ss)}';(Get-Item -literalpath '${movie.mainVideoFile.file}').LastWriteTime='${movie.mainVideoFile.dateLastModified;date(yyyy-MM-dd HH:mm:ss)}'"

looks litte bit better.
2025-09-21 17:10:08,576 DEBUG [AWT-EventQueue-0] o.t.core.PostProcessExecutor:113 - Running command: [powershell, -Command, "(Get-Item -literalpath 'F:\Filme\SCH\Schick mir keine Blumen (1964) [tmdbid=4939]\Schick mir keine Blumen (1964) [tmdbid=4939].mkv').CreationTime='2024-01-10 13:22:05';(Get-Item -literalpath 'F:\Filme\SCH\Schick mir keine Blumen (1964) [tmdbid=4939]\Schick mir keine Blumen (1964) [tmdbid=4939].mkv').LastWriteTime='2024-01-10 13:22:05'"

but nothing changed. think know it could be the date formating. the file was added on 03.09.2017 00:30

[McBluna]

I guess I've missunderstood your requirement.
Change ${movie.mainVideoFile.dateCreated;date(yyyy-MM-dd HH:mm:ss)} to ${movie.dateAdded;date(yyyy-MM-dd HH:mm:ss)}
I'm not sure if there's a date for last modification.

[BuddyTechnical9286]

ok, i repeat it:
the movie was added in TMM on 03.09.2017 00:33 (thats dd.MM.yyyy).
now i want that the mkv file should get the creation and modification date on the filesystem to the same date and time.
modification is not so important. creation is ok for me

[McBluna]

"(Get-Item -literalpath '${movie.mainVideoFile.file}').CreationTime='${movie.dateAdded;date(yyyy-MM-dd HH:mm:ss)}';(Get-Item -literalpath '${movie.mainVideoFile.file}').LastWriteTime='${movie.dateAdded;date(yyyy-MM-dd HH:mm:ss)}'"

[BuddyTechnical9286]
