How do you change the date modified on a file?

I recorded many photos and videos with an Akoso action camera, but I never thought to change the camera's stored time. Only after creation of the files did I see that date and time stamps were saved on top of the files. While I cannot change the images without editing them, I am hoping I can at least change the file properties.

Any way to change these date/time file properties? If so, even if just a simple script, I could then batch something for a larger folder of such pictures. Preferably I can input some offset.

I occasionally use BulkFileChanger by NirSoft.

The latest version also supports batch edits.

"BulkFileChanger is a small utility that allows you to create files list from multiple folders, and then make some action on them - Modify their created/modified/accessed time, change their file attribute (Read Only, Hidden, System), run an executable with these files as parameter, and copy/cut paste into Explorer."

If I may promote my own tool: SKTimeStamp

After installing it, you can select the files in the Windows Explorer, right click and chose Properties from the context menu. Then in the properties dialog you'll find a new tab where you can modify the file times and dates easily.

It's open source, source code can be found on GitHub

If you have the touch program installed, or if you can get it installed, open the command prompt and type:

touch -d "2020-11-01" file
