Disk Usage Monitor - detecting abandoned temp files
I don't have a tool to suggest, but for USB work it would be nice to have a tool which watched for CHANGE in the file count & size in various directories, such that one could be prewarned of problems.
For example, I just ran Open Office & edited a Calc file (loaded as the Portableapps.com bundle). Before, the OO directory held 2460 file in 357 directories with 171MB of data (but chewing up 228MB of space). After there were 2461 files ... hmm, where was the extra file created? Is it an abandoned temp file? Am I going to gain 1 file every time I run OO?
Second example, I just ran across a bug or incompatibility between FireFox and a USB-based virus scanner. This caused FireFox to create and abandon up to 2MB of temp files per hour. I noticed only because I had seen previously that FF consumed about 38MB of disk space ... and later I saw it was 61MB so investigated.
