Portable grepWin

Portable grepWin is a small and easy-to-carry version of an app that was designed to help the user find any particular file or files on a machine. It doesn't matter what format or name it has, if it exists on your device's HDD or SSD, then it can be found.
When compared to the already available tools in Windows, the difference comes in the customizable search features, which make this particular action very accurate and effective.

Filled with features

While the app doesn't have submenus or any such additional option panes, its single and only window displays many features and options that can customize your query. One can enable a case-sensitive search, treat files as UTF 8 or adjust the size limit in order to exclude certain directories or files.
The idea behind this app is to sort of automate the process of finding certain phrases or texts and have them replaced with something indicated by the user. The high level of query customization is the most relevant aspect. Another aspect is the option of conducting Regex searches beside normal Text querries.

Limiting the search

The idea behind imposing certain limits to your search is to actually narrow down your circle of files. This can be done by employing one of the many options. For starters, one can include all file sizes, which doesn't actually limit anything. It would be far more advisable to choose a certain value as a reference and set the app to look for less or more than that certain value.
The search can also be customized in reference to the creation date. Decide if what you're looking for is older or newer than a certain date. A between option is also available if you have a specific time frame in mind. Finally, decide if you want to include subfolders and system items, hidden or binary files, all depending on where you think you might find what you're looking for.
Portable grepWin is a helpful application for finding files and text within these, offering a highly customizable environment for conducting the actual search wrapped in a simple and intuitive interface that can be carried on any simple USB stick for use with any available system.
