Do you have experience with working with spaces in file names that provides insight into whether they are problematic? Should we continue to recommend that digital object creators avoid spaces in file names, or is it an obsolete concern? File names should only contain letters, numbers, underscores, or dashes. Special characters are often reserved for functions in scripting and programming languages, and using these characters in file names can cause problems.
I haven't run into specific problems with spaces personally, but this is a case of good digital object hygiene. For the most part, we've built systems to handle these kinds of problems and exceptions, but sometimes you bump into a hard limit or a piece of bad code. For example,.
In our diverse environment of computing systems, we have a lot of little quirks of what is and is not allowed between systems. Here's a good list of reserved characters that might be restricted in different systems. A file may perform perfectly in one environment, but as it passes from use to preservation or one colleague to another, you can bump into quirky problems that require major workarounds. Advances in computing have made moving files between different platforms much easier than just a few years ago.
The adoption of the UNICODE standard for character encoding and cross compatibility between operating systems has made problems opening a file received as an attachment to an email, downloaded from a web site, or accessed on a cloud storage platform extremely rare, but problems can still occur. While the vast majority of desktop computers still use Microsoft Windows or the Macintosh OS, there remain many other operating systems and file systems that can interact with files at different points.
Cell phones, tape drives, networking equipment, televisions, and even digital cameras support file systems today. Most file systems today, and the operating systems that incorporate them, support much longer file names than the personal computers that ran Microsoft DOS and early versions of Windows. These computers used the 8. However, it is still possible to run into problems related to filename length. File naming is also an important consideration when transferring files via the Internet, where it may not be evident what computer platform was used when the files were originally created.
File names can be either descriptive or non-descriptive. Most cameras include a facility to define how files are named, and accented with characters such as dashes. There are way too many models to reference here, but a quick review of your user manual should reveal the options for your particular camera make and model.
You can also configure how you prefer files to be named in in Lightroom. Those keywords provide a signal of what the page is about and help with your rankings.
Every little thing helps with making your site or images searchable. The potential problems from changing these URLs might be worse than the potential gains from having dashes rather than underscores in them. Should you choose to convert to dashes for all new images and blog posts moving forward, you should feel confident you can do so without any negative repercussions.
