If you move files to an external harddisk which is too small the files get moved until it is totally filled up. You than get an error "an unknown error has occured". When you then free up some space and move certain folders manually it says in some cases "There is already a folder called ###"

What product are you using? Elements? Lightroom? Photoshop?

No problem. What OS/version are you using?

When you get the warning "There is already a folder called ###" are you sure there isn't a folder with that name still present (either on the driver or in the trash)?

This error is probably because a folder was created by the OS, but due to the previous error, it's not in the Lr catalog, no?

Bear in mind that resource allocation failures (like memory and disk) are very hard to handle at an application level. By the time the error in an API call bubbles to the top, it can be interpreted in a variety of ways.

Because you aren't always getting a clear "oh, the disk is full" back from the OS. Rather, you can get a variety of returns, and depending on what you are doing, and what depends on thay, this has to be reinterpreted to provide information back to the user.

Something like this can only be tightened up, but it cannot be made 100% accurate.

That's true. Especially with low RAM situations.

I suggest a better way to handle is to check for sufficient storage on destination before moving - like all those installers do...

Then instead of:

"An unknown error occurred"

after x% complete, one gets:

"There isn't enough room"

before copy/move begins.

Doncha think?
