Johan, Currently Photoshop refuses to overwrite files (unless they have the word "copy" in the title.)
Here's my process.
I open up "Poster Design.psd" which has layers.
I save the file as "Poster For Print.jpg" as a jpeg file without layers.
This works as expected.
I realize I have the date in the poster wrong and I misspelled a word.
I open up "Poster Design.psd" which has layers.
I change the date and fix my spelling error.
I choose "Save As..." and tell Photoshop to save as a jpeg file without layers.
I tell it to name the file "Poster For Print.jpg"
Photoshop tells me a file already exists with this name and asks if I want to overwrite it.
I tell Photoshop "Yes, overwrite the file."
Photoshop then saves the file as "Poster For Print copy.jpg"
The file was not overwritten.
And if I'm not careful, I send my client the wrong image.
I have tested this with jpg, png, tif, and psd documents. The same behavior happens each time.
The use case is I'm trying to save a flattened version of my psd in a different format, replacing an older save in that format, while keeping my psd as a separate file with layers for future revisions if necessary.
Right now, if I flatten my image in Photoshop, the program will correctly overwrite the file without adding the word " copy" to the filename. This means I either need to rename my file to remove the word copy (after deleting the old version) or I have to flatten my image, save the file in the required format, and then flatten the image so I can save the PSD.
And here's why I know it's a bug. If I repeat my process described above, but call my file "Poster For Print copy.jpg" Photoshop will overwrite the image, just like it says it will.
I'm more than willing to provide a video of this issue, if you'd like to see my process.
