How to compact files and folders at the Comman Line

COMPACT [/C | /U] [/S[:dir]] [/A] [/I] [/F] [/Q] [filename [...]]

/C Compresses the specified files. Directories will be marked
so that files added afterward will be compressed.
/U Uncompresses the specified files. Directories will be marked
so that files added afterward will not be compressed.
/S Performs the specified operation on files in the given
directory and all subdirectories. Default "dir" is the
current directory.
/A Displays files with the hidden or system attributes. These
files are omitted by default.
/I Continues performing the specified operation even after errors
have occurred. By default, COMPACT stops when an error is
encountered.
/F Forces the compress operation on all specified files, even
those which are already compressed. Already-compressed files
are skipped by default.
/Q Reports only the most essential information.
filename Specifies a pattern, file, or directory.

Used without parameters, COMPACT displays the compression state of
the current directory and any files it contains. You may use multiple
filenames and wildcards. You must put spaces between multiple
parameters.

Changing System Restore Options in the Windows Registry

In most situations, the default System Restore operation is satisfactory. However
there might be situations in which you need to change how System Restore functions. There are four settings that you can change in the Windows Registry tha affect the intervals System Restore uses when creating automatic restore point and the disk space it uses.
Each of these settings is located in the HKEY_LOCAL_MACHINE\SOFT
WARE\Microsoft\Windows NT\CurrentVersion\SystemRestore subkey.
These settings include the following:
1.RPSessionInterval This setting specifies the intervals, in seconds between scheduled restore-point creations during an active user session. The default value is 0 seconds (disabled).
2.RPGlobalInterval This setting specifies the time interval, in seconds, a which scheduled restore points are created (regardless of whether or no there is an active user session). The default value is 86,400 seconds (24 hours).
3.RPLifeInterval This setting specifies the time interval, in seconds, for which restore points are kept. System Restore deletes restore points older than the specified value. The default value is 7,776,000 seconds (90 days).
4.DiskPercent This setting specifies the maximum amount of disk space on each drive that System Restore can use. This value is specified as a percentage of the total drive space. The default value is 12 percent.
