HSweep

Everything related to the web or accessed this way is recognizable by the associated extension which represents the domain. However, the info of interest might be hiding somewhere in your text files. To find email addresses and links in the blink of an eye, HSweep can take care of looking through all files.

Scan a single file or entire directory

The application is good to from the moment download is done and you can store it on a thumb drive in case you want to carry it around to use on other computers as well. This means that no system registry entries need to be modified to enable functionality, so you can use it without having to worry that the health status of the target PC is affected.
You choose to scan either an entire directory, or only a file if you really know where the address is. Drag and drop is not supported, but using the browse dialog is not a difficult task. Note that the scan starts as soon as you load the file or directory of interest, but there’s also the chance to set up several parameters before scanning starts.

Apply filters and export results

Filters come in the form of keywords, which can be any detail of interest which can narrow down results to your advantage. You can add more keywords, or look for specific extensions by writing them down in a dedicated field. Additionally, you can choose to perform a local sweep to exclude subfolders.
It can take a bit of time to have results shown, but this depends on the depth of folders and files you select for the operation. Identified links can’t be copied, but there is the possibility to export the entire list under a custom text document format.

In conclusion

All things considered, we can safely state that HSweep is sure to help you locate web links of interest or a list of email addresses lost somewhere inside a large text collection. No installation is required, while input can come in the form of an entire directory, or only a specific file. Scanning doesn’t take a lot of time, and you can easily save results for later processing.
