A few years back I was involved with writing a DAM system. Basically the users would save a file to a remote share, this share was actually a thin FUSE implementation that would rip out the metadata from the .psd files, and then save those to a SQL DB, so users could quickly find documents based on partial string matches, link them to physical products in the inventory tracker, etc. After a fairly short development cycle we were ready for a beta deploy. We installed the software, re-routed the shares, and saved a file from Adobe:
"Data error on save"
Hrm...that's odd, so I copied the file by hand to the share. It worked fine. I save the file with a different program, no problems. After some time I decided it had to be a issue with Photoshop. So I called Adobe tech support to see if they could offer some tips. The conversation went something like this:
"So we're trying to save the file to a remote share, and I'm getting a data error on save message...any ideas?"
"By remote share, are you saying you're saving to a network drive?"
"Yes"
"Um sir, that's a unsupported operation...."
"Wait...what? This is the 21st century....you're saying your software can't save to a network drive? How am I supposed to transfer files to a different machine?"
"I suggest you have your users save to their desktop and then copy the file by hand..."
"But what on earth could be causing this sort of issue, every other program I use writes to a network file just fine!"
"Well sir, this is fairly complicated software...."
"Are there any plans to support this in future releases?"
"Not that I know of..."
That was with Photoshop CS3....last I checked the same policy applied....saving to a network share is "unsupported".
