Folder can contain predefined variables: {DATE} – current date, {DATETIME} – the current date and time (format variable {DATETIME} you can change with this key /DTF), {YEAR} – year number, {MONTHNAME} – name of the month, {DAYNAME} – weekday name, {MONTHOFYEAR} – month number of the year, {WEEKOFYEAR} – week number of the year, {WEEK OF MONTH} – week number of the month, {DAYOFYEAR} – day number of the year, {DAYOFMONTH} – day number of the month, {DAYOFWEEK} – day number of the week, {HOUR} – hour, {MIN} – minutes, {SEC} – seconds, {MSEC} – millisecond In all date and time variables, you can add or subtract values. For example {WEEKOFYEAR-1} will take one week from the current week number in the year and {DAYNAME+1} will return the name of the next day of the week. Calculations are always made from the current date and time. It is allowed to use (perl compatible) regular expressions in masks: a. Regular expression validation includes the full path to the file or folder, case-insensitive comparison {R=Regular expression} or case-sensitive comparison {r=Regular expression}. b. the regular expression check does not include the full path to the file or folder, case-insensitive comparison {E=Regular expression} or case-sensitive comparison {e=Regular expression}.
Keys
/? or /H – this help /RUS russian help /S use PowerShell (removes paths longer than 255 characters) /M or /R move to recycle bin /MF[ FileMask[ FileMask] …] Move only files to trash. Default mask * (all). /NMF[ FileMask[ FileMask] …] Do not move files to the trash. Default mask * (all). /MD[ FoldersMask[ FoldersMask] …] Move only folders to the trash. Default mask * (all). /NMD[ FoldersMask[ FoldersMask] …] Do not move to the trash folder. Default mask * (all). /OF[ FileMask[ FileMask] …] delete only files matching masks, leaving folders.

Default mask * (all). Allows you to use other keys for subfolders. /NPT[ FoldersMask[ FoldersMask] …] prevent pass-through folders and subfolders. Default mask * (all). It makes sense only in combination with the key /PT /OSD only files and subfolders delete, leaving main folder (not compatible mit key /OF) /MIN FreeSize The minimum free space in the target volume in bytes below which deletion occurs. /RW[ FileMask[ FileMask] …] before deleting seven times overwrite the contents of files according to the standard 5220.22-M. Default mask * (all). Not compatible mit keys /M or /R ! Greatly slows down deletion! /NRW[ FileMask[ FileMask] …] Do NOT overwrite the contents of files as specified in 5220.22-M before deleting seven times. It makes sense only in combination with the /RW key. Default mask * (all). IMPORTANT! If you create shadow copies, do not forget to delete them. /T Test mode. A list of objects to delete is displayed on the screen. The deletion itself does not occur. /L Display a log (slows removal!) /P Pause at the end of the program /TM[ Nsec] Delete only files with date and time changes within the last Nsec seconds (countdown from the current time). Default Nsec = 3600 (one hour) /NTM[ Nsec] Delete only files with the date and time of the change older than Nsec seconds (countdown from the current time). Default Nsec = 3600 (one hour) /DT[ Ndays] Delete only files with the date of change within the last Ndays days (countdown from the current date, time is discarded and is not taken into account). Default Ndays=0 (today) /SZF NSizeBytes Delete only files larger than or equal to NSizeBytes bytes. /SZT NSizeBytes Delete only files smaller than or equal to NSizeBytes bytes /DTS DD.MM.YYYY Delete only files with a change date greater than or equal to DD.MM.YYYY date (eg 01.09.2015) day of the month, MM is the month, YYYY is the year. Important – leading zeros are required! /DTE DD.MM.YYYY Delete only files with a change date less than than or equal to DD.MM.YYYY date (eg 01.09.2015) (where DD is the day of the month, MM is the month, YYYY is the year. Important – leading zeros are required! /AF [FileMask1=]Attributes1[ [FileMask2=]Attributes[ ….]] Delete files with the specified mask depending on the attributes. Attributes that start with a plus sign – add the file to the list for deletion and with a minus sign – are excluded from the delete list. Possible attributes R – read only, A – archive, S – system, H – hidden, C – compressed, N – not indexed, O – not connected, E – encrypted, T – temporary. The shortened form is allowed – without the file mask and the equal sign, in this case the mask will be the default * For example: /AF -H-S *.doc=+A *.tmp=-A /DTF [Mask date] mask the date and time to output (used in variables {DATETIME}). (default mask yyyymmddhhnnss) Date mask can contain the following control characters: y = Year of the last 2 digits, yy = year from the last 2 digits, yyyy = year 4-digit, m = number of the month without 0, mm = month number as 2 digits, mmm = Month using ShortDayNames (Jan), mmmm = month using LongDayNames (January), d = number without 0, dd = 2 as the number of digits, ddd = number using ShortDayNames (Sun), dddd = number using LongDayNames (Sunday), ddddd = number in ShortDateFormat, dddddd = number in LongDateFormat, c = Using ShortDateFormat + LongTimeFormat, h = hour without 0, hh = hour as a 2 digit, n = minutes without 0, nn = minutes as 2 digits, s = seconds without 0, ss = Seconds as 2 numbers, z = Milliseconds without 0, zzz = Milliseconds as 2 digits, t = Using ShortTimeFormat, tt = Using LongTimeFormat and any other permissible in file names and folder symbols. /CP CodePage – Code page number for the console output (default 65001 – UTF8). Possible values: 0 – ANSI, 1 – OEM, 2 – MAC, 3 – threads ANSI, 866 – OEM RUS, 65000 – UTF7, 65001 – UTF8 etc -1 (Minus) turns off the coding changes. Console font should allow display of this encoding! (Consolas for UTF8)
Examples
Example 1: delt c:\Temp Recursively delete folder c:\Temp without transferring it to recycle bin Example 2: delt c:\Temp /M Move folder c:\Temp to recycle bin Example 3: delt c:\Backup\{WEEKOFYEAR-1} /S /MIN 130000000000 Quickly recursively delete folder c:\Backup\(previous week number of the year) if there is less than 130 GB of free space left on the disk without transferring it to recycle bin. Note for example 3: if the command delt c:\Backup\{WEEKOFYEAR-1} /S /MIN 130000000000 is run before the backup command: copymikc:\Dociments c:\Backup\Documents\{WEEKOFYEAR} /b then the disk is always guaranteed to be 130 gigabytes of free space for backup.
