The strangest thing… I had several PSD files in a subdirectory. Any of the files over 5 megs would not upload to my FTP or website server. As soon as an upload began, the FTP program would disconnect. Used both CuteFTP and Filezilla. (passive mode was active.) Files smaller than 5 meg would upload. Files anywhere else on the computer would also upload no matter what size.

I even moved the PSD files to a different directory – they would not upload. I moved then to a different computer… They would not upload.

Finally I ZIP’d them and they did upload…

Any idea what was going on????

Keep in mind, all other files, PSD and otherwise, no matter what the size would upload fine… I’m baffled….????

Hey Fellow SE Pennsylvanian…long time no see.

Give this a try, Mr. eyewoo:

Make a copy of one of the PSD files that’s under 5MB, and that will presently make the trip to your server(s) without a problem. Move THE COPY to a safe place so it won’t be touched.

Now, in the original PSD file, copy enough layers or layer sets to bring it up over 5 MB. Save it with the EXACT same name you had been using (be mindful of letter-case) and to the same directory where it lived before and, as the under-5MB file, allowed you to upload.

Now, try uploading this over-5MB file using the same methods that worked for the original file.

What happens?

I tried a bunch of stuff… I went through a process of deleting layers from the file a few at a time and then seeing if I could upload. When I finally got it down to about 5 layers and around 750Kb in size (from 25 megs), it started to upload. I then tried to isolate layers to see if there was one that was causing the problem… If so, I could not find it…

I’m out of time… can’t contiue this experiment… I have deadlines…

Damn, I hate being baffled like this….

OK…OK… I am now able to recreate the situation with PSD files not uploading… Here’s how it works… forget what I’ve written earlier…

I created a file with a number of layers and removed a couple at a time until the PSD file would upload. It started to upload sporadically when it had only 6 layers. At less than 6 layers it uploaded fine. At 8 layers, it would not upload at all.

The 8 layer file was 22 megs. So I reduced it to see if size made a differnce. I reduced it to 600 x 800 pixels at 1.8 megs. It would still not upload.

I reduced it to 100 x 133 pixels at 83 Kb. It would still not upload. I combined three layers in the 100 x 133 pixel file so there were only 5 layers…. and it uploaded fine….

What is going on here?????? It sure seems like the number of layers is causing the problem… But why?

FTP and HTTP uploads do not succeed or fail based on the contents of the file; they succeed or fail because the total bytes making up the file either go through or not.

It sounds like a size problem. Are you by any chance on a PPPoE broadband connection? If so, is your MTU set to 1492 (or lower), as it needs to be, instead of the default of 1500? With MTU set too high on a PPPoE connection, large uploads will often fail while smaller ones will succeed.
