I am experiencing the following issue: When I try to get file properties in mql4 using FileGetInteger() it is working for all extensinons (at least those I tried) but is not working for .dll files. What I mean - when I try to check any property (FILE_EXISTS, FILE_CREATE_DATE, FILE_MODIFY_DATE etc.) I get -1 if the file is with .dll extension. When I change it to .dl or txt or anything else the function returns the requested property. What I want to accomplish - check if .dll file is present and if true Alert("File present") if false Alert("File Missing). Workaraounds accepted :) Thanks in advance to everyone who responds.
