When I do a "Save MetaData to File" operation, Photoshop Elements Organizer places a copy of the file in C://Users/[user]/AppData/Local/Temp/ and does not delete it. Over time this begins to consume a lot of disk space, expecially when I'm working with .tif and raw files. Fortunatele Windows does warn me when the C: drive is running low on space. This has been happening now for many months and the first time I ran low on C: drive space it took quite a bit of time to figure out where the free space had gone. Please fix this ASAP.
There were copies of .jpg files, .tif files, .nef and .xmp files. At times there were several hundred of them and it used up most of the remaining space on my SSD C-drive causing Windows to give me a critical storage warning. Once I figured out where all my free space had gone, I made it a routine step of my process to go check for these files and delete them.
