I got called in a couple of weeks ago when the computer started to have trouble handling emails. Soon found that its 32 GB C: partition, containing Windows, only had a few MB spare space. In turn that was because the Windows\Temp folder contained 18 GB of unwanted rubbish dating back a long time. Most of this was from nearly 300 pairs of files named (HHHHHH.tmp (~62.5 MB) and hhhhhh.dmp (225 kb)), where HHHHHH and hhhhhh are strings of hex characters, nearly always six characters but occasionally five. The two files in each pair always have the same time stamp but their names are different. Deleting them fixed the immediate problem, however it is set to recur. When I went back a week later another dozen or so file pairs had appeared, already nearly a GB.
Initial testing suggested that these files were left whenever IE or Firefox browsers were closed; however last night I established that they are left behind whenever the OS (XP3, fully updated afaik) is shut down. The .tmp files are mostly about 62.500 MB, plus or minus only around 50 or 60 kB, although a few get as large as 63 and as small as 61 MB. Iím guessing that the difference could something to do with the length of the session.
Looking at the files with a text editor didn't provide any useful info, and a registry cleaner didnít report anything untoward. Has anyone seen this sort of thing and, importantly, can you suggest what I should try?
The two obvious cures are to re-install Windows Ė which Iím reluctant to attempt because of the complexity of the stuff on the machine Ė and to ask the owner not to turn the machine off between sessions. However thereís no way sheíll do that.
Any suggestions will be gratefully received
