FileActions - AddGap
Set the position of the beginning of the next zone. This command is commonly
used to create a gap at the end of the zone, making the zone bigger than necessary
for the files in the zone, but the command can also be used to position a zone
anywhere on disk.
- The command will be skipped (not executed) if the zone is empty (no files are
selected by the FileBoolean).
- The NUMBER specifies the beginning of the next zone, an absolute position on
the disk. Usually it will be the ZoneEnd plus a number of bytes, but you can
specify a different formula.
- The command will do nothing if the NUMBER is negative. It is an absolute
position on disk, and a negative number would be before the beginning of the
disk.
- The program will automatically vacate the gap between the current end of the
zone and the NUMBER. It will not vacate if the DoNotVacate option is specified,
or if the NUMBER is lower than current end of the zone (negative gap).
- If all the next zones are sorted zones (using one of the SortBy fileactions)
then DoNotVacate can be used, it will save some unnecessary data movements.
- The
FastFill and MoveDownFill
fileactions will only move files down, never up, so files that are in a
DoNotVacate gap will be left in the gap.
Syntax
AddGap(NUMBER [, DoNotVacate]) |
Example
# Add a gap of 1% of the free size of the volume.
AddGap(ZoneEnd + VolumeFree * 0.01)
# Same, but do not vacate.
AddGap(ZoneEnd + VolumeFree * 0.01 , DoNotVacate)
# Add a gap 1% of the volume size:
AddGap(ZoneEnd + VolumeSize * 0.01)
# Add a gap of 1000 clusters.
AddGap(ZoneEnd + 1000 * BytesPerCluster)
# Add a gap 10% of the size of the MFT.
AddGap(ZoneEnd + MftSize * 0.1) |
