Is My SSD Subjected To DOUBLE READS & WRITES when I Play A Game?

Is My SSD Subjected To DOUBLE READS & WRITES when I Play A Game if I compress a game folder? Does it decompress every time I play or is it played in compressed state?

I want to save space but I do not want my SSD working overtime. Thank you,

No, decompression happens entirely in-memory — it's not written back to disk unless the file is being decompressed permanently.

Thank you sir, for your prompt and concise explanation.

Okay, compressed a folder.

1. Should the folder turn blue if I have "Show Compressed Folder In Color" option selected? Or, since not all folders may be compressed, will the ones that were compressible change color?

2. How can I determine which folder I compressed using Windows Explorer or your software or must I keep a written log of folders that I compressed?

3. If I compress folder "A", on drive "D" and subsequently compress the entire drive "D" will your software skip folder "A" during the whole drive "D" compression phase?

1. No, that setting only works with the older NTFS compression scheme.
2. Right click on the folder, Properties, see if Size on disk is much smaller than Size. Or see if Compactor reports any compressed files after analysis. If you want a detailed per-file breakdown, open a command prompt and use the compact command — without arguments it'll print the compression status of all files in the current directory.
3. It'll skip any files in A that were already compressed, or that were recorded as incompressible.
