Location Of Windows Log Files
Hi Sleepy Dude,Thanks for the useful info.1. Referring back to your original reply of 26 Dec 2015, are old cbspersist CAB files just as safe to delete as old LOG files? In other words, can just the most recent dated CAB file be left, along with the most recent dated LOG file?
Or can all the CAB files be safely deleted?2. As for the sfc scan run after the previous old LOG files were deleted (& again today after another cleaning), the result was the same: 'did not find any integrity violations'. However, this machine does run low on HDD space from time-to-time, which seems to be the cause of the accumulation of old LOG & CAB files.I'd be interested in your answer to # 1, and your take on # 2, whenever you have a couple of minutes.
Your insight is truly appreciated.
Junk files are files that remain on your computer after a task has been performed. Sometimes, Windows or some program needs to create temporary files while doing some task and then forgets to delete the temporary files it created.

Because I've seen this question asked in many places and not answered, I thought I'd post my issue and resolution here. I regard this as a Bug, but I'm not invested enough to deal with the support incident process.I've had repeated instances where a Windows 7 x64 client runs out of hard drive space, and found that C:WindowsTEMP is being consumed with hundreds of files with names following the pattern 'cabXXXXX', generally 100 MB each, and these files are constantlygenerated until the system runs out of space. Upon removing the files & rebooting, the files start being generated again.I've found that this is caused by large Component-Based Servicing logs.
These are stored at C:WindowsLogsCBS. The current log file is named 'cbs.log'. When 'cbs.log' reaches a certain size, a cleanup process renames the log to 'CbsPersistYYYYMMDDHHMMSS.log'and then attempts to compress it into a.cab file.However, when the cbs.log reaches a size of 2 GB before that cleanup process compresses it, the file is to large to be handled by the makecab.exe utility. The log file is renamed to CbsPersistdatetime.log, but when the makecab process attempts to compressit the process fails (but only after consuming some 100 MB under WindowsTemp).
After this, the cleanup process runs repeatedly (approx every 20 minutes in my experience). The process fails every time, and also consumes a new 100 MB in WindowsTemp beforedying. This is repeated until the system runs out of drive space.This can be reproduced by trying to manually create the cab file -Directory of C:CBS-BAK 02:28 PM. OH MY GOD this is what's been going on.The thing that gets me is that Windows hides the contents of c:windowstemp by default.
