DOS Expressions

Top  Previous  Next


DOS Expressions use the familiar wildcards * and ? to specify groups of files, e.g. *.pdf to specify a group of files with the PDF extension. However, FileLocator Pro extends the normal DOS expression functionality with some additional special characters:






Matches zero or more characters

Tower*London - file/folder with Tower followed by London in their name.


Matches any single character

*.as?x - files with a four letter extensions that begin with AS and end X, e.g. Page.aspx or Home.ascx.


Start of file indicator

<New - file/folder must begin with New, eg. New York Trip.txt but not My New Recipes.


End of file indicator

LA> - file/folder must end in LA, eg. Parks in LA OR Details.SLA but not LAMP.


Expands search by adding another allowable name/group

*.pdf;*.txt;*.doc - files with PDF, TXT and DOC extension.


Restricts search to only those with a specified name/group

*.pdf;*.doc:London - PDF or DOC files that have London in their name.


Excludes a name/group from the search

NOT:*.dll;*.exe;*.sys - all files except DLL, EXE, and SYS files


Concatenate multiple search expressions

*.pdf:London|*.txt:Tower - PDF files with London in their name OR TXT files with Tower in their name.


Used to either quote semi-colon ';' character or specify word boundary

"LA" - file/folder with the word LA in their name, eg. LA Flight details.txt but not LAMP.txt.
